Three Years, Not Five

This is the first article in a rebuilt Niche Industry Operational Finance silo. It concerns roughly a million and a half Canadian households, every accountant who audits a condominium corporation, and a document most directors receive, skim and file.

The Verdict, Stated First

Five claims, in descending order of confidence.

One. The update cycle is three years. Both the Condominium Authority of Ontario and the Condominium Management Regulatory Authority of Ontario state it plainly, in materials published for boards.

Two. Published guidance disagrees with itself. We found three different cycles asserted across three sources, and one page contradicts its own summary two paragraphs later.

Three. Ontario sets no minimum reserve balance and no minimum percentage funded. Adequacy is measured against your own study and your own funding plan, not against a benchmark.

Four. On our own arithmetic, a contribution shortfall compounds fast, because the same expenditures must be funded over fewer remaining years from a smaller balance.

Five. And on our own arithmetic, the deferral is a transfer between owners, since the assessment lands on whoever holds the unit on the day it is levied.

The first two are why we published this before the funding models, ours. A funding model applied to the wrong deadline is worse than no article.

A Warning About Dates

A standing feature of every article in this silo, and it matters more here than most. Ours.

Four observations.

Every statutory reference in this article was verified on 29 August 2026, and the regulation carries amendments through at least O. Reg. 397/17[4].

Condominium legislation is provincial and amended regularly. British Columbia changed its depreciation report regime on 1 July 2024[8], which is recent enough that older guidance is now wrong.

So the shelf life of the compliance content here is shorter than the shelf life of the arithmetic, and a reader should treat the two differently.

And the practical instruction is one line. Check the current regulation before acting, and treat any undated web page about condominium deadlines as unreliable, which is a lesson this article demonstrates rather than asserts.

Our Grades For These Claims

Applying the scheme this publication uses throughout.

Grade A for the three-year cycle, stated by two separate Ontario regulators in materials written for boards[1][2][3].

Grade A for the citation conflict, since we obtained all three sources and quote them.

Grade B for the regulation's operative text. We obtained the definitions section verbatim from the government's own site[4] and could not retrieve the full text of sections 27 through 31, so the cycle rests on regulator summaries rather than on the section we would prefer to quote.

Grade C for the fifteen-year adequacy provision, which reaches us from an engineering firm rather than from the statute[7].

Grade A for our own arithmetic, with every business figure invented and marked.

A Note On Method

Everything here is verified to 29 August 2026.

We obtained the Condominium Authority of Ontario's public guidance and its published guide for directors[1][2], and the Condominium Management Regulatory Authority of Ontario's explanation[3]. Both are statutory regulators.

We obtained verbatim definitional text from the regulation on the Government of Ontario site[4].

We did not obtain the full text of O. Reg. 48/01 sections 27 to 31, which is the passage that sets the cycle. One legal database refused automated access and the government page returned only fragments. This is the weakest link in the article and we flag it here rather than in a footnote.

We did not obtain the Condominium Act itself in full, and cite its sections as the regulators identify them.

All arithmetic is ours. The corporation, its balance, its expenditures and every rate are invented to demonstrate a structure.

This article discusses condominium legislation and capital planning. It is not legal, engineering or accounting advice, and a board should retain qualified professionals.

Three Sources, Three Cycles

The finding, laid out as we encountered it. Ours.

We were researching funding models. Checking the update cycle should have taken two minutes. It took an afternoon, because the published sources do not agree.

Source one, a regulator: after the first class 1 study, class 3 and class 2 studies are done on an alternating basis at least every three years[1].

Source two, a firm's guidance page: reserve fund studies must be updated at least every 5 years for established corporations[6].

Source three, a CPA-reviewed page: a comprehensive class 1 study is required every six years[5].

Four observations.

These are not different framings of one rule. They are three different compliance deadlines, and a board can only satisfy one of them.

All three pages are written for the same audience, are indexed, and read as authoritative. None of them is obviously the odd one out from its presentation.

Two of the three are dated 2026, so this is not stale guidance describing a superseded regime.

And a reader with no reason to check would take whichever page they landed on. That is the ordinary case, and it is why we led with this rather than with the arithmetic.

The Five-Year Claim

The more serious of the two, examined. Ours.

The page states that "Ontario Regulation 48/01 requires an update at least every 5 years for established corporations, with newer corporations facing a faster initial cycle (roughly year 1, then year 3) before settling into the standard 5-year schedule."[6]

Its source list gives: "Government of Ontario, O. Reg. 48/01 under the Condominium Act, 1998: Ontario reserve fund studies must be updated at least every 5 years, with a faster initial cycle for new corporations."[6]

Four observations.

The regulation is cited as the authority for the five-year figure. That is a direct attribution to a primary source, which is what makes this worse than an ordinary error.

The page also gets the initial cycle approximately right, at year one then year three, and then asserts the corporation settles into five years, which no regulator source describes.

The gap between three and five years is two years of compliance exposure. A board following it would believe itself current while the statutory deadline had passed.

And we would note what we cannot say, ours. We could not retrieve the operative sections of the regulation directly, so our position rests on two regulators contradicting the page rather than on our own reading of the text.

The Six-Year Claim

The stranger of the two, because the page argues with itself. Ours.

Its summary states: "Studies are required under Section 94 and Ontario Regulation 48/01 — comprehensive Class 1 study every six years, updated Class 2 or Class 3 study at least every three years, plus annual budget updates."[5]

Its body then states: "In practice, most boards follow a three-year alternating rhythm (Class 1 in year 0, Class 3 in year 3, Class 2 in year 6, etc.)."[5]

Four observations.

The body describes a Class 1 that happens once, in year zero, and never recurs. The summary describes one that recurs every six years. They cannot both be right.

The body's version matches the regulators: Class 1, then Class 3 at year three, then Class 2 at year six[1].

The page carries a named CPA reviewer and a review date, which is more disclosure than most pages offer and did not prevent the error.

And the mechanism is one we would guess rather than know, ours. A summary written after the body, to be scannable, is where precision goes, and this is what that looks like.

What The Regulators Say

The position we take, and its basis.

The Condominium Authority of Ontario states: "A condo corporation must complete a class 1 study within the first year following the registration of the declaration and description. After the first class 1 study is done, the class 3 and class 2 studies are done on an alternating basis at least every three years."[1]

The Condominium Management Regulatory Authority of Ontario states: "A condo corporation must complete a class 1 study within the first year following registration of the declaration and description. After that, a Class 3 study must be completed within three years, followed by a Class 2 within 3 years after that date. Class 2 and Class 3 studies then must be completed every 3 years on an alternating basis."[3]

Four observations, ours.

These are two different regulators saying the same thing, in their own words, in materials aimed at boards and managers respectively.

The CMRAO version is the more precise and is worth quoting to a provider. It names the order: Class 3 first, then Class 2, which matters because a Class 3 requires no site inspection and a Class 2 does.

Both describe Class 1 as a single event tied to registration, not a recurring obligation.

And the regulator's guide adds the projection horizon. "The 30-year timeline is a legislated minimum"[2], which is a floor rather than a target.

The Three Classes

What each actually involves, from the regulators' descriptions.

Class 1, comprehensive. Providers physically examine the property, review records and interview directors, employees and agents, and make at least a 30-year projection[1]. Content requirements are in section 29 of the regulation.

Class 2, updated with a site inspection. Includes a site inspection and many of the requirements of the comprehensive study, per section 30(2)[1].

Class 3, updated without a site inspection. Requires only a review of records and interviews with the directors, employees and agents[1].

Four observations, ours.

The regulation's own definition of the third class is worth reading closely: "a comprehensive study that has been revised so that it is current as of the date of the revision, where the revision is not based on a site inspection of the property"[4].

So a Class 3 is the previous study, revised, and its quality is bounded by the quality of the records the corporation can supply.

Which has an operational consequence most boards miss. Poor records make the cheapest study the least reliable, and the corporation pays for that at the next site inspection when the component list is wrong.

And Class 1 and Class 2 require both a physical and a financial analysis, where a Class 3 requires the financial analysis[2]. The engineering half is what alternates; the money half never stops.

The Fifteen-Year Provision

A rule we had not seen discussed and which changes how a shortfall is read.

An engineering firm's summary states: "A reserve fund that is found to be inadequate must be brought up to an acceptable level within 15 years of the date the first reserve fund study is done, on or after May 5, 2001."[7]

An engineering firm rather than a statute or regulator, flagged, and we did not verify it against the regulation.

Four observations, ours.

If accurate, it converts an open-ended obligation into a dated one, which is a materially different thing for a board to plan against.

It also explains a pattern practitioners describe. A corporation can be underfunded and compliant simultaneously, provided it is on a plan that closes the gap inside the window.

A separate fragment of the regulation we retrieved refers to a 10-year period for the purposes of subsection 94(8) in certain transitional cases involving corporations created before section 94 came into force[4], which is a different provision and should not be confused with the fifteen.

And we would not act on either figure without checking the current regulation, ours. Two different horizons, from two different sources, neither verified against the operative text, is exactly the situation this article opened by describing.

There Is No Minimum

The most commonly misunderstood point, and it is well sourced.

Ontario sets no minimum reserve fund balance and no minimum percentage. Adequacy is judged against the corporation's own study and the funding plan the board proposes under section 94(8), not against a fixed number. A percent funded figure is an industry comparison, not an Ontario legal requirement[9].

Four observations, ours.

This surprises directors, who frequently arrive believing there is a threshold. There is no seventy percent rule and no hundred percent rule in Ontario law.

The consequence is that a corporation cannot be compliant by hitting a benchmark, and cannot be non-compliant by missing one. The test is the plan.

It also means comparing your percent funded to another building's tells you very little, since the two studies rest on different component lists, different useful lives and different cost assumptions.

And it puts the weight on the assumptions, ours, which is where the rest of this article goes.

A Restricted Fund

The accounting frame, which decides how everything else is presented.

The reserve fund is legally restricted under section 93 of the Condominium Act, and may only pay for major repair and replacement of common elements and assets. Interest earned on reserve investments belongs to the reserve fund and cannot be transferred to the operating fund under section 93(3)[5]. Section 115 restricts investments to eligible securities[5].

These points come from the CPA-reviewed page whose cycle summary we contradicted above, flagged. We report them because they are consistent with the regulators' framing and because a source being wrong about one thing does not make it wrong about everything.

Four observations, ours.

Restricted fund accounting means the reserve is presented separately, and a corporation cannot solve an operating deficit by reaching into it.

The interest rule has a quiet effect on the arithmetic below. Investment income accrues inside the fund, so it reduces the required contribution rather than relieving the operating budget.

The investment restriction caps what that income can be. Eligible securities are conservative by design, which is appropriate for the purpose and constrains the return assumption.

And that constraint is the hinge of the whole funding question, ours. A fund restricted to safe instruments in an inflationary period earns a real return close to zero, which we now compute.

What A Shortfall Actually Costs

Our own arithmetic on an invented corporation. Every figure below is ours and illustrative.

A 120-unit corporation. Reserve balance $900,000. Thirty-year projected expenditures $14.4 million. Current annual contribution $310,000. Inflation assumed at 3 percent and investment return at 3.5 percent.

The real rate of return, being the investment return net of inflation, is 0.49 percent.

Discounting the expenditure stream at that real rate gives a present value of $13,370,433. Less the opening balance of $900,000, the required level annual contribution is $447,690.

Against a current contribution of $310,000, that is a shortfall of $137,690 a year, or a 44.4 percent increase.

Four observations.

The real rate is the number doing the work, and at 0.49 percent the fund is barely outrunning inflation, which is what a portfolio of eligible securities looks like in an inflationary period.

A 44 percent increase in the reserve contribution is not a 44 percent increase in common expenses, since the reserve is one component of the budget. On these figures it would be a materially smaller headline increase.

The figures are invented and the structure is not. Any board can run this with its own study's numbers in a spreadsheet, and should, because the study's own funding plan is one of several defensible plans rather than the only one.

And the sensitivity to the return assumption is the point we return to below. Move the return by half a percent and the required contribution moves substantially, which is why that input deserves more attention than it gets.

What Each Year Of Delay Adds

Our own arithmetic, and this is the section we would put in front of a reluctant board.

Suppose the board receives the study, accepts the analysis and defers the increase. The same expenditures must then be funded over fewer remaining years, from a balance that has grown more slowly than planned.

Adopting the increase today requires $447,690, a rise of 44.4 percent. After one year: $466,186, a rise of 50.4 percent. After two: $486,119, or 56.8 percent. After three: $507,650, or 63.8 percent. After five: $556,294, or 79.4 percent.

Four observations.

Five years of delay takes the required increase from 44 percent to 79. The board has not avoided the increase; it has enlarged it.

The mechanism is two-sided and that is why it compounds. The remaining funding period shrinks while the costs inflate, so the numerator rises as the denominator falls.

Three years is the interval that matters institutionally, ours, because it is one study cycle. A board that defers to the next study is choosing the 63.8 percent column.

And the political arithmetic runs against the financial arithmetic every time. The 44 percent increase is unpopular now and the 79 percent increase is somebody else's problem, which is the whole difficulty.

The Special Assessment Alternative

Our own arithmetic, expressing the same shortfall the way owners will eventually experience it.

If the shortfall is met by special assessment rather than by contributions, the accumulated gap on our invented corporation comes to $137,690 after one year, which is $1,147 per unit. After three years, $413,070, or $3,442 per unit. After five, $688,450, or $5,737. After ten, $1,376,899, or $11,474 per unit.

Four observations.

The monthly increase avoided becomes a lump sum owed, and the lump sum is the form owners find hardest to fund.

A special assessment also arrives without warning to a purchaser who bought on the strength of a status certificate showing modest fees, which is where the disputes come from.

These are invented figures and the per-unit numbers are the ones we would sanity-check hardest, ours. They assume the shortfall is spread evenly across units, where a real corporation allocates by unit factor.

And we note one thing about the three-year figure without leaning on it. It lands near a widely quoted average special assessment we could not verify, which we discuss below rather than treat as confirmation.

Who Pays And Who Benefited

The distributional point, which is the real objection to underfunding. Ours.

Four observations.

A reserve fund exists so that each year's owners pay for the wear they cause, rather than the owners present when the roof fails paying for thirty years of everyone's use.

Underfunding reverses that. Low fees are enjoyed by the owners of the underfunded years and the assessment lands on whoever holds the unit on the levy date, who may have bought last month.

The transfer is not small on our figures. Ten years of underfunding is $11,474 per unit, moved from people who have sold to people who have just arrived.

And it is invisible in the ordinary case, ours, because nobody itemises it. The seller's gain appears as a lower carrying cost and the buyer's loss appears as an unexpected bill, and the two are never connected.

The Least Examined Input

Where we would spend a board's attention if it had one hour. Ours.

Four observations.

Most board discussion of a study concerns the component list and the timing: is the roof really due in year eight, is that elevator estimate current.

Almost none concerns the inflation and return assumptions, which on our arithmetic move the answer more than any single component does.

The reason is that the assumptions are printed once, in a table, and the components are printed over many pages, so attention follows page count rather than materiality.

And the check is simple enough to do in the meeting, ours. Ask what real return the plan assumes, being the investment return less inflation, and ask what the required contribution becomes if that real return is zero.

Two Ways To Fund The Same Building

A distinction that produces very different contribution schedules from identical engineering. Ours.

The regulation contemplates contributions "determined on a cash flow basis" that offset adequately the expected cost in the year of each item's expected major repair or replacement[4].

Four observations.

A cash flow approach asks only that the fund never go negative across the projection. It permits a lower balance and a lower contribution, and it accepts that the fund is nearly drained after a large expenditure.

A component approach funds each item toward its own replacement, so the balance at any date approximates the accumulated wear on the building. It produces a higher balance and a higher contribution.

Both can be described as adequate, ours, and they are not equally safe. A fund run at a cash flow minimum has no capacity to absorb an estimate that was wrong, and estimates thirty years out are frequently wrong.

And the choice is rarely presented to boards as a choice. The study arrives with a plan already selected, and a board can ask what the other one would have required.

What The Study Cannot Tell You

The limits of the instrument, which its own regulator states plainly. Ours.

The Condominium Authority of Ontario's guidance is direct: reserve fund studies can only provide an estimate of future costs, and are similar to a homeowner's plan for saving to keep a home in good repair[1].

Four observations.

That framing is more modest than the document's appearance suggests. A bound report full of tables reads as a measurement and is a projection, and the two invite different amounts of confidence.

Three things the study does not attempt: it does not price the risk that a component fails early, it does not model an interest rate environment different from the one assumed, and it does not know what the corporation will actually decide to spend.

The regulator also advises planning for high-risk components like balconies or parking structures[2], which is the closest the guidance comes to acknowledging variance around the estimate.

And the practical response is not to distrust the study, ours. It is to hold a margin above whatever plan it recommends, on the reasoning that a projection with no stated uncertainty is not a ceiling.

What The Auditor Receives

The part that concerns our own profession, and it is more specific than most accountants expect.

The board must send the corporation's auditor copies of the reserve fund study, the proposed plan for future funding, and the notice sent to owners[9]. Owners must receive the notice within 15 days of the plan being proposed, and the board implements the plan 30 days from the date it was sent to owners and the auditor[1].

Four observations, ours.

So the auditor is a named recipient by regulation, not merely someone who asks for the study during fieldwork.

That timing is worth noting. The auditor receives the plan before it is implemented, which is a window that exists in the rules and is rarely used for anything.

What the auditor does with it is a separate question we are not answering here. An audit of a condominium corporation is an audit of financial statements, not an opinion on whether a funding plan is wise.

And there is a practical opportunity in the sequence, ours. An accountant who reads the plan on arrival rather than at year end can raise an arithmetic question while the board can still act on it, which costs an hour.

British Columbia And Alberta

Because the silo serves a national readership and the regimes differ.

In British Columbia the equivalent document is the depreciation report under the Strata Property Act, funding the contingency reserve fund. As of 1 July 2024, a depreciation report is mandatory for strata corporations with five or more lots, on a five-year cycle, and strata corporations can no longer hold an annual three-quarter vote to defer it[8].

Alberta requires a reserve fund study under its own condominium legislation[8].

Four observations, ours.

The British Columbia change is recent and consequential, since the removal of the deferral vote ends a mechanism many strata corporations used repeatedly.

Note that British Columbia's cycle is five years and Ontario's is three, which is very likely where some of the confusion documented above originates.

We did not obtain the British Columbia or Alberta statutes and report both through a single secondary source, which is thinner sourcing than the Ontario material.

And the general instruction follows, ours. Guidance written for one province is not guidance for another, and a page that does not name its province should not be relied on at all.

Three Statistics We Declined To Use

Reported because the omissions are informative. Ours.

We encountered three striking figures that would have improved this article and could not verify any of them.

That the Ontario Auditor General found 69 percent of reserve funds underfunded, and that the average special assessment is $3,525 per unit, both attributed to the Auditor General by a commercial reserve-study vendor with no report year or page given.

And that 16 percent of condominiums issued a special assessment between 2018 and 2023, from a lending firm's guidance page.

Four observations.

All three are the kind of figure that gets quoted onward, ours, and we would have quoted them had we not made a rule against it.

The first two carry a specific attribution to a government auditor, which is what makes their unsourced presentation a problem rather than merely a gap.

We note that our own three-year per-unit figure of $3,442 sits close to the unverified $3,525. That is a coincidence between an invented model and an unverified claim, and it is worth exactly nothing as corroboration of either.

And we say so explicitly because the temptation ran the other way. Two numbers agreeing feels like evidence and is not, when neither has been established.

If You Sit On A Board

Practical, and not legal or engineering advice. Ours.

Four points.

Confirm your cycle against the regulator, not against a web page. This article exists because three published sources gave three different answers.

Ask the provider for the real return assumption, being investment return less inflation, and what the plan looks like if it is zero.

Price the delay before you vote on it. On our own invented figures, three years of deferral moves a 44 percent increase to 64 percent, and the arithmetic takes ten minutes with your own numbers.

And keep the records the Class 3 will depend on. The cheapest study in the cycle is a revision of the last one, and its accuracy is bounded by what you can hand over.

If You Audit One

For our own profession. Ours, and not a statement of assurance standards.

Four points.

You are a named recipient of the study, the plan and the owner notice. That is a regulatory delivery, not a document request.

Read the plan when it arrives rather than at year end, since it reaches you before implementation and the board can still act.

Check the interest rule. Investment income earned on reserve assets belongs to the reserve and cannot be moved to operating, which is a presentation error worth looking for.

And expect no benchmark. There is no minimum balance or percentage in Ontario, so a client asking whether they are adequately funded is asking about their own plan and nothing else.

What To Do

Treat three years as the Ontario update cycle, on both regulators' published guidance, and verify against the current regulation before acting.

Distrust undated guidance on condominium deadlines. We found a five-year claim citing the regulation as its authority and a six-year claim contradicted by its own page.

Remember that Class 1 is a single event tied to registration on the regulators' account, followed by Class 3 then Class 2 alternating.

Stop comparing your percent funded to other buildings. Ontario sets no minimum and the comparison is between two different sets of assumptions.

Interrogate the real return assumption, which on our own arithmetic moves the required contribution more than any single component estimate.

Price a deferral in dollars per unit before voting on it. On our figures, ten years of underfunding is $11,474 per unit, transferred from sellers to buyers.

Check which province a source is describing. British Columbia's depreciation report runs on a five-year cycle and its deferral vote was removed on 1 July 2024.

And do not quote the 69 percent figure. We could not verify it, and neither, apparently, did the pages repeating it.

The Limits Of This Analysis

Several caveats matter. This article discusses condominium legislation and capital planning and is not legal, engineering, accounting or investment advice; a board should retain qualified professionals and confirm every deadline against the current regulation. All legislative references were verified on 29 August 2026 and condominium legislation is provincial and amended regularly, so this content has a shorter shelf life than most on this site. We did not obtain the full text of O. Reg. 48/01 sections 27 to 31, which is the passage setting the study cycle: one legal database refused automated access and the government site returned only fragments, so our position on the three-year cycle rests on two regulators' published summaries rather than on our own reading of the operative text. That is the weakest link in this article and we would revise it if the section reads differently. We did not obtain the Condominium Act, 1998 in full, and cite its sections as the regulators identify them. The fifteen-year adequacy provision comes from an engineering firm's summary, flagged, and was not verified against the regulation; a separate ten-year period we found in a regulation fragment concerns transitional cases and should not be confused with it. The restricted fund, interest and investment points come from a source whose study-cycle summary we contradict elsewhere in this article, flagged; we report them because they are consistent with the regulators' framing, and a reader may reasonably discount them. We did not obtain the British Columbia Strata Property Act or Alberta's condominium legislation, and report both provinces through a single secondary source. All arithmetic is ours. The 120 units, the $900,000 balance, the $14.4 million expenditure projection, the $310,000 contribution, the 3 percent inflation and 3.5 percent return are invented by us to demonstrate a structure; the per-unit assessment figures assume an even spread where a real corporation allocates by unit factor. And three statistics we encountered were excluded as unverified, including a 69 percent underfunding figure attributed to Ontario's Auditor General, which we mention only to say we did not use it.

Frequently Asked Questions

How often does an Ontario condo need a reserve fund study?

Both Ontario regulators state that a Class 1 comprehensive study is completed within the first year following registration of the declaration and description, and that Class 3 and Class 2 studies then alternate at least every three years. We found published sources claiming five and six year cycles, which conflict with that guidance. Verify against the current regulation before acting.

Is there a minimum reserve fund balance in Ontario?

No. Ontario sets no minimum balance and no minimum percentage funded. Adequacy is judged against your own study and the funding plan the board proposes under section 94(8). A percent funded figure is an industry comparison, not a legal requirement, and comparing it across buildings compares two different sets of assumptions.

What does deferring a contribution increase cost?

On our own arithmetic for an invented 120-unit corporation, a needed increase of 44.4 percent becomes 63.8 percent if deferred three years and 79.4 percent if deferred five. The same expenditures must be funded over fewer remaining years from a smaller balance, so the shortfall compounds from both directions.

What is the difference between the three classes of study?

Class 1 is comprehensive, involving physical examination, records review and interviews, with at least a 30-year projection. Class 2 is an update that includes a site inspection. Class 3 is an update based only on records review and interviews, with no site inspection, and the regulation defines it as the comprehensive study revised to be current as of the revision date.

Does the auditor see the reserve fund study?

Yes, as a named recipient. The board must send the auditor copies of the study, the proposed funding plan and the notice sent to owners. Owners receive the notice within 15 days of the plan being proposed, and the plan is implemented 30 days after being sent to owners and the auditor.

How does British Columbia differ?

British Columbia uses a depreciation report under the Strata Property Act, funding the contingency reserve fund. As of 1 July 2024 it is mandatory for strata corporations with five or more lots on a five-year cycle, and the annual three-quarter vote to defer has been removed. We report this through a single secondary source and did not obtain the statute.

Why does this article not cite the 69 percent underfunding statistic?

Because we could not verify it. It is attributed to Ontario's Auditor General by a commercial reserve-study vendor with no report year or page number given, alongside an average special assessment figure of $3,525 per unit. Both would have strengthened this article and neither was established, so we excluded them and said so.

4. Government of Ontario e-Laws page for O. Reg. 48/01 under the Condominium Act, 1998, from which we obtained the verbatim definition that an "updated study not based on a site inspection" means a comprehensive study that has been revised so that it is current as of the date of the revision, where the revision is not based on a site inspection of the property and where the revision has been conducted in accordance with the requirements of the Regulation; together with the amendment history for section 1 (O. Reg. 48/01, s. 1; O. Reg. 383/12, s. 1; O. Reg. 180/17, s. 1 (1-3); O. Reg. 397/17, s. 1). A separate archived copy of the regulation records a prescribed period of 10 years from the date of the first reserve fund study for the purposes of subsection 94(8) in certain transitional cases involving corporations created before section 94 came into force. Note: the primary source. We obtained the definitions section and amendment history verbatim and COULD NOT RETRIEVE the full text of sections 27 to 31, which set the cycle. This is the weakest link in the article. ontario.ca
5. Accounting firm guidance page on reserve fund study accounting in Ontario, carrying a named CPA reviewer and a review date of 30 July 2026. Its summary states that studies are required under Section 94 and Ontario Regulation 48/01 with a comprehensive Class 1 study every six years and an updated Class 2 or Class 3 study at least every three years. Its body states that in practice most boards follow a three-year alternating rhythm with Class 1 in year 0, Class 3 in year 3 and Class 2 in year 6. It also states that the reserve fund is legally restricted under Section 93 and may only pay for major repair and replacement of common elements and assets; that interest earned on reserve investments belongs to the reserve fund and cannot be transferred to the operating fund under Section 93(3); that Section 115 restricts investments to eligible securities; and that only a Licensed Public Accountant may sign the audit report owners receive under Section 84. Note: a competitor accounting firm's guidance page, NOT a regulator. Cited for the six-year claim documented in this article, which its own body text contradicts, and separately for the restricted fund and interest points, which are consistent with the regulators' framing. A reader may reasonably discount the second set given the first. insightscpa.ca
6. Guidance page on condominium reserve fund studies, stating that Ontario Regulation 48/01 requires an update at least every 5 years for established corporations, with newer corporations facing a faster initial cycle of roughly year 1 then year 3 before settling into the standard 5-year schedule; and listing among its sources "Government of Ontario, O. Reg. 48/01 under the Condominium Act, 1998: Ontario reserve fund studies must be updated at least every 5 years, with a faster initial cycle for new corporations." Note: NOT a regulator. Cited solely to document the five-year claim examined in this article, and the attribution of that claim to the regulation itself. We do not rely on this source for anything. boarddeadline.com
7. Engineering firm overview of reserve fund studies, stating that corporations created before May 5, 2001 must obtain a comprehensive study by May 5, 2004 or conduct an updated study based on a site inspection if a compliant comprehensive study is already in hand; describing the three classifications and the rule that an update not based on a site visit can only be done if the study just prior was a comprehensive study or an update based on a site visit; stating that a reserve fund found to be inadequate must be brought up to an acceptable level within 15 years of the date the first reserve fund study is done on or after May 5, 2001; and that within 120 days of receiving a study the corporation must present owners a financial plan for funding the reserve. Note: an engineering firm, NOT a regulator or statute, flagged. Our only source for the fifteen-year adequacy provision, which we did not verify against the regulation. cdwengineering.com
8. Condominium lending firm's guide to reserve fund studies, stating that every province requires a study in some form, being the reserve fund study in Ontario and Alberta and the depreciation report for strata corporations in British Columbia; that under the Condominium Act, 1998 and Ontario Regulation 48/01 a corporation completes a comprehensive study within the first year after registration then updates it on an alternating basis with or without a site visit at least every three years; and that as of July 1, 2024 a depreciation report is mandatory for British Columbia strata corporations with five or more lots on a five-year cycle, with strata corporations no longer able to hold an annual three-quarter vote to defer it. It also states that 16 percent of condos issued a special assessment between 2018 and 2023. Note: a lending firm, NOT a regulator, flagged. Our only source for the British Columbia and Alberta position, which we did not verify against either provincial statute. Its 16 percent special assessment figure is one of the three statistics this article declines to use. condolending.com
9. Owner advocacy guide to Ontario reserve fund studies, stating that section 94(1) requires periodic studies to determine whether the money in the fund and the contributions being collected are adequate; that Ontario does not set a minimum reserve fund balance or a minimum percentage; that adequacy is judged against the corporation's own study and the funding plan proposed under section 94(8) rather than a fixed number; that a percent funded figure is an industry comparison and not an Ontario legal requirement; that sections 27 to 33 of the regulation set the three classes, the three year cycle, the required contents and the 30 year funding plan; and that the board must send the corporation's auditor copies of the study, the proposed plan and the owner notice. Note: an advocacy publication, NOT a regulator, flagged. Used for the no-minimum point, which is consistent with the regulators' framing, and for the auditor delivery requirement. condoowneradvocate.ca

This article discusses condominium legislation and capital planning and is not legal, engineering, accounting or investment advice. All legislative references were verified on 29 August 2026; condominium legislation is provincial and amended regularly, and every deadline should be confirmed against the current regulation before acting. The full text of O. Reg. 48/01 sections 27 to 31 was not obtained. All arithmetic is the authors' own and every business figure in it is invented to demonstrate a structure.
