Key takeaways
  • You have a 10-day cooling-off period to rescind a pre-construction condo agreement, and the agreement does not bind you until you receive the disclosure statement and the Residential Condominium Buyers' Guide.
  • A material change in the disclosure statement can also give you a right to rescind.
  • If the unit is not ready by the Outside Occupancy Date, you have 30 days to terminate.

You signed for a unit that will not exist for years, and now your finances, plans or the market look different. Before you assume your deposit is gone, it helps to know which exits Ontario law gives you.

There is no general right to walk away at any time. There are specific windows and grounds, and missing them can be costly, so the timing matters.

The 10-day cooling-off period

A buyer of a pre-construction condo has a 10-day cooling-off period to rescind the agreement of purchase and sale. The agreement also does not bind you until you receive both the disclosure statement and Ontario's Residential Condominium Buyers' Guide.

That second point is easy to miss. If you were never given one of those documents, ask a lawyer how it affects the start of your rights. Do not rely on a date that you assumed.

Rescinding after a material change

A buyer may also rescind after a material change in the information in the disclosure statement. Builders sometimes revise plans, unit sizes or other details between signing and closing. Whether a given change is material is a question of fact, and a lawyer can compare the original statement to the amended one.

Terminating over delays

If the unit is not ready by the Outside Occupancy Date, you have 30 days to terminate the agreement. The Tarion Addendum overrides any conflicting terms, and early-termination conditions that the Addendum does not allow cannot be enforced.

Not every delay lets you leave. While the occupancy date is tentative, the builder may extend it several times without paying compensation, but must give 90 days' notice of each extension. For unavoidable delays, the builder may extend all deadlines by up to the length of the delay.

Delay situationWhat the rules say
Tentative date extendedAllowed several times, with 90 days' notice each time
No 10 days' notice of an occupancy delayBuilder pays the buyer $1,500
Closing date changeGenerally needs at least 90 days' written notice
Delay compensationUp to $7,500 in total, with living expenses at a fixed $150 a day, no receipts needed
Not ready by Outside Occupancy Date30 days to terminate

Time limits for making a delayed-occupancy claim are described in more than one way, so confirm the deadline that applies to you with Tarion or a lawyer as soon as a delay notice arrives. Keep every notice the builder sends you, because the dates on them often decide what you can do.

What happens to your deposit

Builders must generally hold deposits and other money received for a condo project in trust. Tarion protects deposits and other payments, including upgrades and extras, up to $20,000 plus a limited amount of interest. That protection applies where the builder goes bankrupt, fundamentally breaches the agreement, or the buyer rescinds before closing and the deal does not close.

For deposits above $20,000 per unit, Tarion's builder security requirements say condo vendors must use a separate trust account, the trust account run by the escrow agent, or excess deposit insurance. If a condo builder ends the agreement, it must return your whole deposit within 10 days.

Payments made to reserve or hold a unit before you sign the purchase agreement have no Tarion deposit protection.

If you simply decide not to close and have no valid ground, what happens to your deposit depends on the wording of your agreement and the facts. Do not assume you can recover it, and do not stop paying instalments without advice.

Costs to weigh before you decide

If you are thinking about staying in the deal, it helps to see the costs that come before and at closing. Some of them surprise buyers.

Condo builders must list extra charges and expected adjustments to the final price, with dollar values, in Schedule B of the Tarion Addendum. Compare those numbers with your budget before you decide whether to close or look for a way out.

What to do next

Frequently asked questions

How long is the cooling-off period?

It is 10 days to rescind a pre-construction condo agreement, and the agreement does not bind you until you receive both the disclosure statement and the Residential Condominium Buyers' Guide. Confirm the exact start date with a lawyer.

Can I cancel because the project is late?

Only in certain situations. If the unit is not ready by the Outside Occupancy Date, you have 30 days to terminate. Tentative dates can be extended several times with 90 days' notice and no compensation.

Can I back out if the plans change?

You may be able to rescind after a material change in the disclosure statement information. Whether the change is material depends on the facts.

Will I get my deposit back if I walk away late?

It depends on your agreement and whether you have a valid ground. Tarion deposit protection applies where the buyer rescinds before closing and the deal does not close, among other cases, but a lawyer should check how it fits your situation.
