Most people buying a condo know that a special assessment is a thing that can happen to them. Far fewer know how little stands between them and one, or that the law was supposed to change on this point and quietly did not.

This is not a scary story. The real numbers, which I will give you below, are more reassuring than the horror stories going around. But it is a story about knowing what actually protects you, because a protection you assume you have and do not is worse than knowing you never had it.

What a special assessment actually is

There is no such thing, legally, as a “special assessment” in Ontario. The term is industry shorthand. What the Condominium Act, 1998 describes is assessments levied against a unit to increase the contribution to the reserve fund, and it treats them as part of your ordinary common expenses.

That matters for a practical reason. Your share is not negotiated and it is not per-person. It is your unit’s proportion of the common expenses, set out in the corporation’s declaration. If the building needs a new roof and the reserve fund is short, your bill is the shortfall multiplied by your percentage, whether you moved in twenty years ago or last month.

The protections that expired in December

Ontario passed a large package of condo reforms in 2015, the Protecting Condominium Owners Act. Many of its provisions were brought into force. Some never were, and unproclaimed provisions carry a ten-year deadline.

That deadline arrived at the end of 2025. Bill 72, which received Royal Assent on December 11, 2025, extended the deadline for some of the remaining provisions. It did not extend the ones concerning reserve funds and chargebacks, and those expired on December 31, 2025. The Condominium Authority of Ontario confirmed the split the day after Royal Assent.

Two of the lapsed items would have mattered to owners. One would have given the Condominium Authority Tribunal jurisdiction over chargeback disputes, which is the difference between a cheap accessible tribunal and going to court. The other would have brought clarity to what counts as an adequate reserve fund, a term the Act uses without defining. Reviving either would now require new legislation. As of this writing I have found no indication that is planned.

I want to be careful about what this does and does not mean. Nothing got worse in December. The law simply stayed as it was in 1998 and 2001. But the improvement that condo owners had been told was coming is not coming, and the industry noticed even if buyers did not: the Canadian Condominium Institute’s Toronto chapter was still pressing the Auditor General about this lapse in May of this year.

What that gap looks like in practice

This spring the Toronto Star followed an Ontario condo owner through exactly the kind of dispute those lapsed provisions were meant to cover. In 2018 he refused to pay roughly $10,000 as his share of a building-wide plumbing replacement, believing his own unit did not need it. The dispute went to arbitration, he lost, and he was ordered to pay the corporation’s legal costs.

What happened after that is the part worth understanding. The corporation kept adding its legal fees to his common expense account, year after year. By late 2023 those added fees alone had passed $166,000. His total debt is now reported at more than $262,000, a figure he disputes, and this spring he was served notice that his unit could be sold.

I am not going to tell you who is right in that dispute. I do not know, the amounts themselves are contested, and it is not my story to retell in detail. What matters for a buyer is the mechanism, and an Ottawa condo lawyer with no involvement in the case, speaking about lien law generally rather than about that dispute, put it to the paper plainly: “Liens were never meant to be a sword to enforce compliance. They exist to ensure payment of common expenses.”

Four prospective purchasers walked away from that unit after discovering the lien.

Which is the whole reason this article exists. Not because such cases are common, but because the way a buyer finds out is a document you are entitled to before you commit.

How likely is a special assessment, really

One thing to be clear about before the numbers. What made that case extraordinary was not the original charge, which was an ordinary share of a building-wide repair. It was what came after: legal costs from a dispute compounding onto one owner’s account, year after year. I have not found any data on how often a disagreement escalates that way. What can be measured is the ordinary case, the assessment for a repair, and that comes from the regulator rather than from anecdote.

The Condominium Authority of Ontario surveyed condo corporations across the province and published the results in its 2024 reserve fund survey. Among the corporations that responded, 16 per cent had issued a special assessment at any point in the six years from 2018 to 2023. In 2022 specifically, 5.9 per cent did. And among those that issued one, the average amount per voting unit dropped from $10,050 in 2018 to $3,525 in 2023.

Read that against the figures circulating online, where five-figure-per-unit assessments are described as though they were routine. They happen, and when they happen to you they are genuinely painful. They are not the normal condition of condo ownership.

One caveat: only about six per cent of Ontario’s corporations responded, and they chose to, so the sample is small and self-selected and may not represent every corporation in the province. It is still the only primary dataset I could find on this question, and it is published by the regulator rather than by anyone selling you something.

What actually protects you, and how to use it

The status certificate. It is not glamorous and it does most of the work.

Section 76 of the Act requires the corporation to disclose, for your specific unit, any assessments levied since the budget date to increase the reserve fund contribution and the reason for them, any increase in common expenses the board has declared and why, the most recent reserve fund study and its updates, how much is actually in the reserve fund, and any current plans to increase it.

Three features of it are worth knowing:

  • The corporation must give it to you within 10 days of your request and payment.
  • The fee is capped at $100 including tax.
  • It binds the corporation as against a buyer who relies on it. What that is worth in a specific dispute is a question for your lawyer, but it is the reason the document carries real weight rather than being a courtesy summary.

That last point is the one most buyers do not realise. The status certificate is not a courtesy summary. It is a legally binding disclosure, and it is the cheapest protection in the entire transaction.

Knowing what it must disclose is one thing; knowing how to read it is another. For that, and for the rest of the vetting, see my guide to what to investigate in a condo before you offer.

Who reads it, and what that is worth

Your lawyer reviews the status certificate. That is their work, not mine: what the disclosures mean legally, whether anything required is missing, and what recourse you have if it is. It is one of the reasons the offer condition exists in the first place, and it is why the review time needs to be real rather than a rushed afternoon. If you want to know what a lawyer is actually doing for you in a purchase, I wrote a plain-English guide to what your real estate lawyer does.

I read them too, as an experienced agent rather than as a reviewer, and I will happily say what stands out to me. Sometimes something does. I will not pretend that is a substitute for the legal review, or promise you that I will spot the thing that matters, because a status certificate is a package of documents and what jumps out of one is not predictable. My useful contribution is usually earlier and simpler: making sure you ask for it in time, and knowing which questions are worth putting to your lawyer once you have it.

The reserve fund study itself follows a rhythm you can rely on: under the regulations a corporation must complete one and then repeat it within every three years, and the study has to project a funding plan out at least thirty years. So the information you need exists, on a schedule, in every building you might buy into. The question is only whether anyone reads it before you sign.

Most owners never see one of these: 84 per cent of the corporations that answered the regulator reported no special assessment across those six years. But the difference between a building that is well run and one that is not is written down, it is cheap to obtain, and it is available to you before you commit. That is worth more than a protection the legislature never got around to bringing into force.
