Key takeaways
  • A builder can cancel only under early termination conditions listed in Schedule A of the Tarion Addendum.
  • If a builder terminates, it must return your deposit in full within 10 days.
  • If the builder does not refund, Tarion's deposit protection covers up to $20,000 plus a limited amount of accrued interest.

Getting a letter saying your pre-construction condo is cancelled is upsetting, especially after years of waiting. The first questions are usually whether the builder is allowed to do this and how quickly you get your money back.

This article explains the general rules in Ontario for builder cancellations, deposit refunds, interest and Tarion's deposit protection. Your own agreement and its Tarion Addendum matter a great deal, so a lawyer should review them.

When a builder can cancel

A builder can cancel a pre-construction deal only under the early termination conditions listed in Schedule A of the Tarion Addendum. Each condition must be clearly described in the purchase agreement, with a date by which it must be met. Conditions of a type the Addendum does not permit are unenforceable.

These are typical examples. Whether the builder properly relied on a condition in your agreement is the key question if you want to challenge a cancellation, and a lawyer can review the wording and dates.

Getting your deposit back

Money a condo builder receives, including deposits, must generally be held in trust under the Condominium Act. If a builder terminates, it must return your deposit in full within 10 days.

If a project is cancelled, buyers are generally entitled to their deposit back plus accrued interest at two per cent below the Bank of Canada bank rate. Clear records of every payment you made will make any refund or claim much easier to sort out.

Which interest rate applies

There is an exception for newer situations. Since January 1, 2023, interest is paid at the Bank of Canada policy interest rate where no units were sold before that date and the developer terminates the agreement. The two-per-cent-below rate still applies when the buyer rescinds during the cooling-off period or after a material change.

Project cancelled (general rule)Two per cent below the Bank of Canada bank rate
Developer terminates, no units sold before 2023Bank of Canada policy interest rate
Buyer rescinds in cooling-off period or after material changeTwo per cent below the rate

If the builder does not pay: Tarion

If a builder does not refund a condo deposit, Tarion's deposit protection covers up to $20,000 plus a limited amount of accrued interest. To claim, call Tarion at 1-877-982-7466 for a Deposit Refund Claim Form and submit it with the purchase agreement and cancelled deposit cheques. Assessment can take up to six months.

Tarion cannot force a builder to complete a condominium project it has decided not to proceed with, though you may be eligible for deposit protection. Deposit protection may not cover everything if your deposits were large, so a lawyer can help you understand any gap.

Other buyer rights to know about

A cancellation by the builder is different from your own rights to leave a deal or to be compensated for delay. Knowing the difference helps you see which rules apply to your situation.

Delayed occupancy compensation is capped at $7,500 in total, including a flat $150 a day for living expenses that needs no receipts. Delayed occupancy claims go to the builder within 180 days of the occupancy date or termination date, and if the builder does not pay, you can claim to Tarion during the first year of possession, or up to 365 days after terminating. The dates and amounts in your own Addendum can differ, so confirm them with a lawyer.
