If you purchase a resale home in Ontario and sign a firm agreement, you are legally bound. If you experience buyer's remorse 24 hours later, tough luck—you can be sued for your deposit and damages.
However, under Section 73 of the Ontario Condominium Act, the government provides a massive safety net for buyers of newly constructed condominiums: The 10-Day Cooling-Off Period.
What is the 10-Day Cooling-Off Period?
From the moment you receive the fully signed Agreement of Purchase and Sale (APS) and the developer's Disclosure Statement, a literal clock starts ticking. For the next 10 calendar days, you possess the absolute, unquestionable right to cancel the agreement. You don't need an excuse. You don't lose your deposit. You simply notify the builder in writing, get your deposit cheque back, and walk away clean.
Calendar Days vs. Business Days
In Ontario, the 10 days are strictly Calendar Days, not business days. If you sign the contract on a Friday evening, Saturday and Sunday count as days 1 and 2. Time is of the essence.
How to Weaponize the 10 Days
This period is not for relaxing; it is for mobilizing your team to conduct aggressive due diligence. You must accomplish two things before day 10:
1. The Mortgage Pre-Approval
You must send the APS and the builder's deposit structure to your mortgage broker immediately. They need to verify that your income and credit dictate you will qualify for a mortgage upon closing, assuming current stress test parameters. If your broker says you won't qualify, you cancel the deal.
2. The Legal Document Review
You must send the APS to your specialized real estate lawyer. Builder contracts are notoriously one-sided, often hundreds of pages long, filled with hidden clauses allowing them to change floor plans or pass on absurd fees. Your lawyer will draft an amendment to:
- Cap municipal development charges.
- Cap water and hydro meter installation fees.
- Grant you the right to lease the unit during the interim occupancy phase.
If the builder refuses to accept your lawyer's reasonable caps and amendments, you exercise your right to cancel the contract before the 10th day expires.
