Cooling-Off Period in Ontario Pre-Construction: 10-Day Rights Every Buyer Should Know

When you sign a pre-construction Agreement of Purchase and Sale (APS) in Ontario, you have 10 days to walk away without penalty. This is called the statutory cooling-off period, and it exists because pre-construction contracts are long, complex, and often signed under sales-office pressure.

But the 10 days aren't as simple as "10 days from signing." The clock can pause, reset, or fail to start entirely depending on what the builder gave you — and what they didn't. If you're still inside the window, this guide will help you use it.

Who gets the 10-day cooling-off period?

Under the Protecting Condominium Owners Act, 2015 and section 73 of the Ontario Condominium Act, 1998, every purchaser of a new pre-construction condominium unit in Ontario gets a 10-day rescission period. This is a one-way right — the buyer can walk away, but the builder cannot.

Two important limits:

• Freehold pre-construction homes (detached, semi, town) do not have a statutory cooling-off period. Some builders offer one voluntarily — check Schedule A.
• Resale condos do not have one. The cooling-off period only applies to the very first purchase from the builder.

When does the clock actually start?

The 10 days start on the later of:

• The date you received a fully-signed copy of the APS, or
• The date you received the builder's disclosure statement — which includes the proposed declaration, by-laws, budget, and any amendments.

If the builder later issues a material amendment to the disclosure statement (e.g. the condo fees change, the amenities are reduced, the building design is changed significantly), a fresh 10-day period restarts from the date you receive the amendment. Material amendments are a common way the window re-opens long after closing day was supposed to be "final."

How to exercise the right

To cancel, you must deliver a written notice of rescission to the vendor within the 10 days. Best practice:

• Send it in writing (email + registered mail or courier).
• Address it to the vendor's legal representative as listed in the APS, not just the sales office.
• Keep proof of delivery (tracking number, read receipt).
• Do not rely on a verbal cancellation — it will not hold up.

Once you've rescinded, the builder must return all deposits in full within 10 days, including interest if the builder has held them for more than 60 days. No cancellation fees, no "processing charges."

What does not waive your right?

Builders often imply that selecting finishes, paying an upgrade deposit, or signing a mortgage pre-approval "locks you in." None of that waives your statutory cooling-off period. The right is non-waivable during the 10 days — any clause in the APS that claims otherwise is unenforceable.

Common mistakes that cost buyers

• Waiting too long for "the lawyer to get back." The 10 days include weekends and holidays. If your lawyer takes 12 days to review, you've lost the right.
• Assuming the clock started at deposit. It starts when you have the signed APS and the disclosure statement — which builders sometimes deliver days later.
• Accepting a "deposit refund minus fees" offer. If you rescind within 10 days, the full deposit must come back. Fees are not legal.

What to do in your 10 days

1. Day 1–2: Confirm the start date in writing with the builder's legal rep.
2. Day 1–7: Read Schedule A, Schedule B, and the disclosure statement. These contain the most important clauses (adjustments, delays, assignment, finishes).
3. Day 3–8: Send the APS to a real estate lawyer experienced in pre-construction. A paid review costs $300–$800 and can uncover six-figure risks.
4. Day 7–10: Decide. If rescinding, deliver written notice with proof of delivery before the 10th day ends.

The cooling-off period is often the most valuable right you have as a pre-construction buyer in Ontario — but only if you actually use it. Treat the 10 days as a real deadline, not a formality.
