What is it?
The 10-day cooling-off period is the time the law gives a buyer of a new condo unit from the builder to change their mind. Section 73 of the Condominium Act calls it "rescission" of the agreement. You do not need a reason, there is no penalty, and your money comes back with interest.
The CAO guide describes it as "10 calendar days" and says you cancel for any reason whatsoever simply by notifying the developer in writing. The statute itself says "10 days" and does not say business days. One Tarion web page refers to "10 business day", but it is safest to count calendar days as the Act and the CAO guide do, and to confirm the exact last day with your lawyer.
The right exists only when you buy from the builder (the "declarant") or someone acting for it. When you buy a resale condo from an owner, a resale house, or a new freehold home, there is no such statutory period.
When does it start and end?
The 10 days run from the latest of these three dates:
- The day you receive the disclosure statement
- The day you receive the CAO condo buyers’ guide (Ontario’s Residential Condominium Buyers’ Guide)
- The day you receive a copy of the agreement signed by both the builder and you
The clock starts not when you sign at the sales office, but when the copy signed by the builder is in your hands too. If the documents arrive separately, count from the last one. Record the date and the method (email, paper) for each.
How do you cancel?
- Once you decide, tell your lawyer. The law allows either you or your lawyer to send the notice.
- Write a written notice of rescission. A phone call or telling the sales staff in person does not count.
- The builder (declarant) or its lawyer must receive the notice within the 10 days. It is the date received, not the date sent, so use a method that leaves proof of receipt before the deadline (email plus registered mail, or whatever method the agreement specifies).
- The builder must "promptly" refund all money paid toward the price, without any penalty or charge, together with interest (s. 73 (3)).
- If the money does not come, have your lawyer press for it, and if that fails, claim under Tarion deposit protection (up to $20,000 for a condo). Using a statutory right to rescind is one of the situations Tarion covers.
How much interest?
Section 19 (3) of the regulation (O. Reg. 48/01) sets it. Money refunded on rescission earns interest at 2% a year below the Bank of Canada "bank rate": for April to September, the bank rate as of March 31, and for October to March, the bank rate as of September 30. For projects where no units were sold before January 1, 2023 and the builder terminates the agreement, a different rate applies (based on the policy interest rate, s. 19.1), but the CAO says the "bank rate minus 2%" rate still applies to a 10-day cooling-off cancellation.
The bank rate changes over time, so check the actual rate on the Bank of Canada website and with your lawyer. Because the money comes back within days, the interest itself is small.
What to do during the 10 days
- Have a real estate lawyer experienced in pre-construction review the agreement, the Addendum and the whole disclosure statement. The lawyer can ask for changes to the cap on adjustments, the deposit schedule, assignment terms and early termination conditions, and if the builder refuses you can cancel.
- Talk to a mortgage professional about whether you can fund the balance at a closing years away, and what happens if rates rise in the meantime.
- Check the builder’s licence, cancellation history and discipline in the HCRA Ontario Builder Directory.
- Read the first-year budget in the disclosure statement (projected fees, reserve fund), the rules (pets, short-term rentals) and the share of units the builder plans to lease.
- Talk it over with your family and add up the full cost: deposits, occupancy fees, closing adjustments, HST and land transfer tax.
- If you are going to cancel, do not wait until the last day. Send the notice with a few days to spare.
Can you cancel after the period ends?
As a rule, no. After the 10 days the agreement is firm, and if you change your mind and do not close, you can lose your deposit and be sued for the seller’s losses.
There are a few exceptions. If there is a "material change" to the disclosure statement, section 74 of the Act gives you a new 10-day right to rescind. If the builder misses the outside occupancy date in the Addendum, you have 30 days to terminate. And if the builder ends the agreement because an early termination condition was not met, you get your money back with interest.
One more thing: section 80 (3) of the Act lets you elect, before the cooling-off period ends, to pay the full balance when you take interim occupancy. You then avoid the interest portion of the interim occupancy fee. If you have the cash, it is worth discussing with your lawyer within the 10 days.
What about houses and resale homes?
There is no cooling-off period when you buy a resale home. The moment your offer is accepted it is a contract, and the only ways out are the conditions you put in the offer (financing, home inspection, status certificate review). That is why conditional offers matter in resale.
The 10-day rule in the Condominium Act also does not apply when you buy a new freehold home from a builder. Instead, under the Tarion Addendum, if the builder puts "early termination conditions" in the agreement you get a short 3-business-day cooling-off period to review them, and if project viability conditions (for example, a minimum number of sales) are included you get a 10-day review period. These rights exist only when such conditions are present, so check with your lawyer what conditions your Addendum contains.
Example
On Friday, May 7, 2027 you sign for a pre-construction condo in Markham and pay a $10,000 deposit. You receive the disclosure statement and the CAO guide that day, but the copy of the agreement signed by the builder arrives by email on Tuesday, May 11. You have all three documents as of May 11, so the last day of the cooling-off period is Friday, May 21.
Your lawyer finds no cap on adjustments, a ban on assignment, and a clause letting the builder change the unit size slightly, and asks for amendments. When the builder has not replied by May 18, your lawyer sends a written notice of rescission by email and registered mail on Wednesday, May 19, and the builder’s lawyer confirms receipt the same day. Ten days later your $10,000 deposit comes back with interest. The dates and amounts in this example are for illustration only.

Common questions
Are the 10 days business days or calendar days?
Section 73 says "10 days" and does not say business days, and the CAO guide calls it "10 calendar days". Count weekends and holidays to be safe. If the last day falls on a weekend, make sure the notice arrives by the business day before, and confirm the exact date with your lawyer.
Do I get the whole deposit back if I cancel?
Yes. The law requires all money paid toward the price to be refunded with interest and without any penalty or deduction. Note that money paid before signing to "reserve" a unit is credited to the price once you sign (Condominium Act, s. 81 (3)), but Tarion deposit protection does not cover pre-agreement reservation money.
Can I send the rescission notice by email?
The law only requires a "written notice" that the builder or its lawyer receives within the 10 days. If the agreement specifies a notice method (an email address, fax, mail), follow it and get confirmation of receipt. Sending it through your lawyer is the safest route.
What if the sales office says there is no cooling-off period or "once you sign, it is final"?
A contract to buy a new condo from the builder carries a statutory 10-day right to rescind that the contract cannot remove. The disclosure statement must even include the text of sections 73 and 74 (regulation s. 17). If you hear such claims, treat it as a warning sign and check the builder in the HCRA directory.
I bought a resale home and changed my mind. Can I cancel?
Resale homes have no cooling-off period. If a condition in your offer (financing, inspection and so on) is not met within its deadline you can end the deal and get the deposit back, but a firm contract cannot be cancelled just because you changed your mind: you can lose the deposit and be sued for losses. Talk to a lawyer right away.
