When a Buyer Wants the Whole Condo Building: The 80% Vote and What Dissenters Can Do
A sale of the whole property needs two separate 80% approvals. Once it is authorized, voting yes and voting no leave you with very different exposure, and the no side runs on a 10-day clock.
What vote does it take to sell an entire Ontario condo building, and what is an owner who voted no entitled to?
Two 80% approvals, both counted at the date of the vote: the owners of at least 80 per cent of the units must vote in favour, and at least 80 per cent of those holding registered claims against the property created after the declaration was registered (in practice, mostly mortgage lenders) must consent in writing (Condominium Act, 1998, s.124(2)). An owner who dissented cannot block a sale that clears both thresholds, but can dispute the property’s fair market value, on two deadlines: a notice of intention to the corporation within 10 days after the vote, and a submission to mediation within 30 days of the vote (s.125(3) and (1)). If arbitration sets a value above the sale price, that owner is paid as if the property had sold at that value; any shortfall the proceeds cannot cover is paid by the corporation, and the owners other than those who dissented are liable for it in proportion to their common interests (s.125(5) and (6)).

The meeting ran late. This morning the minutes are not out yet, but you already know the result: the motion to sell the whole property to the buyer cleared the threshold, and you were one of the owners who voted against it. What is easy to miss is that the statute did not stop at the vote. If you want to dispute the price, you have 10 days from that vote to give the corporation written notice of intention, and the clock has already started.
I’m Arthur Zhao with AZ Real Estate Partners. This is an unusual kind of sale: nobody listed your unit, yet it can be sold along with everyone else’s. Below I set out how the Condominium Act, 1998 handles it, organised by where you stand: voting yes, voting no, carrying a mortgage, or owning more than one unit. It is a summary of the statute, not legal advice on your building; for that, bring your meeting package to a lawyer.

Three ways a building leaves the Condominium Act
Part VIII of the Condominium Act, 1998 is headed Termination, and it covers more than one route. Before you decide anything, check which one your notice is actually about.
1. Termination with consent (s.122). The owners of at least 80 per cent of the units vote in favour of termination, and at least 80 per cent of those holding registered claims created after the declaration was registered consent in writing. The corporation then registers a notice of termination. Nobody is bought out. Under s.127(1)(b), the owners become tenants in common of the land in the same proportions as their common interests, and under s.127(1)(d) each unit’s encumbrances become claims against that owner’s interest in the land. The building stops being a condominium, but the owners still own it together.
2. Sale of the property (s.124). The approval thresholds are the same two 80% tests, but the result is different: the corporation conveys the property to a buyer, the Act stops governing it, and the owners share the net proceeds (s.124(1) and (4)). This is the route the rest of this article covers, and it is the only one of the three that comes with the dissent rights in s.125.
3. Termination by court order (s.128). The corporation, an owner, or someone with an encumbrance against a unit can apply to the Superior Court of Justice. The court may terminate if it is just and equitable, having regard to the scheme and intent of the Act, the probability of unfairness to owners, the probability of confusion and uncertainty, and the best interests of the owners.
For completeness, s.123 is a fourth, narrower route: after substantial damage (estimated repair cost of at least 25 per cent of the replacement cost of all buildings and structures), owners of at least 80 per cent of the units can vote to terminate instead of repairing.
If your notice speaks of a purchaser, a purchase price and a vote to authorise a sale, you are looking at s.124.
ℹ️Clause 124(2)(d), which would add “all other conditions, if any, that are prescribed” to the approval requirements, is not yet in force. It takes effect on a day to be named by proclamation. Today, the conditions are the ones in clauses (a) to (c).
Where you stand going into the vote
The same vote produces different results for different owners. Find your position below; more than one may apply to you.
If you intend to vote yes
A yes vote counts toward the first threshold in s.124(2)(a): the owners of at least 80 per cent of the units, at the date of the vote, voting in favour. According to the Condominium Act, 1998 (s.124(4)), if the sale goes ahead you share in the net proceeds with every other owner at the time the deed is registered, in the same proportions as your common interests.
What a yes vote does not settle is the price. Any owner who dissented can, within 30 days of the vote, take a dispute over the property’s fair market value, measured as of the time of the sale, to mediation (s.125(1)). If it goes on to arbitration and the arbitrated value is higher than the sale price, the following provisions apply, in this order:
- s.125(4): each owner who served a notice of intention is entitled to receive from the proceeds what they would have received had the sale price been the arbitrated value.
- s.125(5): if the proceeds are not enough to pay that, the corporation pays those owners the deficiency.
- s.125(6): the owners other than those who dissented on the vote are liable for the deficiency payments, in proportion to their common interests.
- s.125(7): the corporation adds the liability of each owner who voted in favour of the sale to the common expenses for that owner’s unit, and may set a time for payment.
Read (6) and (7) separately. Subsection (6) describes the owners who are liable, and subsection (7) describes the owners whose common expenses the corporation charges. They are worded differently in the statute, and I am not going to blur them into one rule here.
💡 My own view: a yes vote is not the risk-free side. If dissenting owners persuade an arbitrator that the property was worth more than the agreed price, the shortfall does not come out of the buyer. Under s.125(5) to (7) it is carried by the owners who did not dissent, in proportion to their common interests, and it lands on common expenses. So before you vote yes, ask the board one direct question: what valuation supports this price? If the answer is thin, your own exposure grows with the gap between the agreed price and what a dissenter could prove.
If you intend to vote no
Your no vote matters while the count is open, because the sale needs the owners of at least 80 per cent of the units voting in favour. Once that threshold and the written-consent threshold in s.124(2)(b) are both met, a no vote does not stop the sale, and nothing in s.125 lets a dissenting owner keep their unit or require anyone to buy it separately.
According to the Condominium Act, 1998 (s.125(1)), what an owner “who has dissented on the vote authorizing the sale” gets is a right to dispute the fair market value of the property that was sold, determined as of the time of the sale. It runs on two deadlines, both counted from the vote, not from closing:
- Within 10 days after the vote: give the corporation notice of intention (s.125(3)). This is the shorter deadline, and it expires first.
- Within 30 days of the vote: submit the dispute to mediation (s.125(1)).
Section 125(2) then applies s.132 with necessary modifications. Under s.132(1), the disagreement goes first to mediation by a person the parties select and, unless the mediator obtains a settlement, then to arbitration under the Arbitration Act, 1991. If the arbitrated value is higher than the sale price, you receive from the proceeds what you would have received had the property sold at that value (s.125(4)). The entitlement in s.125(4) belongs to an owner who served a notice of intention, so missing the 10-day notice is the costly mistake. If the arbitrated value is not higher, the statute provides no top-up.
The steps are short and the deadlines are tight, so if you are seriously considering this route, have a lawyer look at your notice the day after the vote, not the week before the 30th day.
Voting yes vs voting no: what each position leaves you with
If your unit is mortgaged
Your lender is part of the approval, not a bystander. Section 124(2)(b) requires written consent from at least 80 per cent of those who, at the date of the vote, hold registered claims against the property being sold that were created after the declaration and description were registered. In practice, these are mainly the lenders holding mortgages on individual units.
The reason is what closing does to those claims. When the deed and certificate are registered, claims against the property sold that were created after the declaration was registered are extinguished (s.127(2)(c)). The statute does not set out how each mortgage is paid from the proceeds; that is handled by the lawyers at closing, and you should not assume anything about the numbers until your lender and your lawyer have looked at your file.
⚠️Talk to your lender and your lawyer before the vote, not after. On registration of the deed and certificate, claims against the property sold that were created after the declaration was registered are extinguished (Condominium Act, 1998, s.127(2)(c)). That category includes mortgages registered against units after the condominium was created, and how yours is dealt with at closing is something to understand in advance.
If you own more than one unit, or a parking or locker unit
The threshold in s.124(2)(a) is written as “the owners of at least 80 per cent of the units”. If you own several units, read that wording with your lawyer before assuming how your votes are counted. Whether a parking space or locker is a separate unit at all depends on how your building’s declaration and description set it up. Some buildings make them units; others make them exclusive-use common elements. Check your declaration rather than relying on what neighbours have been told.
One related point from s.124(2.1) and (2.2): an owner whose common expense contributions are 30 days or more in arrears loses the right to consent under clause (2)(c), which only applies when part of the common elements reserved for designated units is sold. It is not a rule about the owners’ vote in clause (2)(a). The right comes back once the arrears are paid.
What closing does
When the sale takes place, the board delivers to the buyer a deed and a certificate in the form prescribed by the Minister, signed by the corporation’s authorized officers, stating that everyone required to vote in favour or consent in writing under s.124(2) has done so (s.124(3)).
Once the deed and certificate are registered, s.127(2) provides that:
- the Condominium Act stops governing the property sold (clause (a));
- claims against the land created before the declaration and description were registered remain as effective as if the condominium had never been registered (clause (b));
- claims against the property sold created after the declaration was registered are extinguished (clause (c)).
The money then moves in two separate streams. The net sale proceeds go to the owners at the time the deed is registered, in proportion to their common interests (s.124(4)), except that proceeds attributable to common elements reserved for certain designated units are divided among those owners according to how their interests are affected (s.124(5)). The corporation’s own assets are dealt with under s.129: they first pay all money claims against the corporation, and the remainder is distributed among the owners in proportion to their common interests.
Two things this article does not cover. Tenants living in units have their own rules under the Residential Tenancies Act, 2006, which is a separate question. Tax treatment of your share is also out of scope; ask your accountant.
Documents to read before the vote
Pull these together while there is still time to ask questions. Each item points to a document, not to a deadline.
- ☐Confirm the notice is for a sale under s.124, not a termination under s.122 or s.123.
- ☐Look for the purchase price and any valuation or appraisal offered to support it.
- ☐Write down the exact date of the vote; both s.125 deadlines run from it.
- ☐Ask the board how the written consents from registered claim holders under s.124(2)(b) are being collected.
- ☐Note which common elements, if any, are reserved for designated units, since s.124(5) divides those proceeds differently.
- ☐Check whether your parking space or locker is a separate unit or an exclusive-use common element.
- ☐Find your unit’s proportion of common interests; it is the basis for both your share of net proceeds (s.124(4)) and any deficiency liability (s.125(6)).
- ☐Ask your lender whether it has been asked to consent in writing, and what it intends to do.
- ☐Ask your lawyer how your mortgage would be dealt with at closing, given s.127(2)(c).
- ☐If you may dissent, have your lawyer prepare the notice of intention so it reaches the corporation within 10 days after the vote.

Frequently Asked Questions
Is the 80% condo sale vote counted by number of units or by how big each owner’s share is?
By units. Section 124(2)(a) of the Condominium Act, 1998 requires the owners of at least 80 per cent of the units, at the date of the vote, to vote in favour. The net proceeds, separately, are shared in proportion to each owner’s common interests under s.124(4).
What if I don’t vote at all on the sale of my condo building?
The Act gives the right to dispute fair market value to “an owner who has dissented on the vote authorizing the sale” (s.125(1)). The deficiency liability falls on “the owners other than those who dissented” (s.125(6)), while the corporation adds that liability to the common expenses of “the owners who voted in favour” (s.125(7)). How those words apply to an owner who did not vote is a question for your lawyer.
Who pays if an arbitrator decides the condo building was worth more than the sale price?
Owners who served a notice of intention are entitled to what they would have received at the arbitrated value (Condominium Act, 1998, s.125(4)). If the proceeds fall short, the corporation pays the deficiency (s.125(5)), the owners other than those who dissented are liable for it in proportion to their common interests (s.125(6)), and the corporation adds it to the common expenses of the owners who voted in favour (s.125(7)).
Is selling the condo building the same as terminating the condominium?
No. Under s.122, termination with consent leaves the owners as tenants in common of the land in proportion to their common interests (s.127(1)(b)). Under s.124, the property is sold to a buyer and the owners share the net proceeds. Both require the same two 80% approvals, but only a s.124 sale carries the dissent rights in s.125.
What happens to the money the condo corporation holds when the building is sold?
Section 129 of the Condominium Act, 1998 says that when the property stops being governed by the Act, the corporation’s assets are first used to pay all money claims against the corporation. Whatever remains is distributed among the owners in proportion to their common interests. This is separate from the sale proceeds shared under s.124(4).
