The ten-day rescission right, the disclosure statement, deposits, interim occupancy, and what changes when you buy by assignment instead of from the builder.

⚖️ This is general information, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.

Pre-construction means signing today for a home that will be built over the next several years. You are buying a contract, and everything about the purchase, from the price to the closing date, depends on that contract's terms and on the statutory protections around it. An assignment purchase adds a second contract: you buy the original purchaser's rights under the builder agreement, and you inherit its obligations. This guide explains both, points to the sections of the Condominium Act, 1998 and the Excise Tax Act that matter most, and lists the questions we ask before you commit.


Ten days to change your mind (condominiums only)

Section 73 of the Condominium Act lets a purchaser rescind an agreement with the declarant by written notice that the declarant receives within ten days of the latest of three events: receipt of the disclosure statement, receipt of the condominium guide, and receipt of the agreement signed by both sides. The declarant must then promptly refund every payment with interest at the prescribed rate. Under section 74, a later material change to the disclosure statement opens a fresh rescission window. This is the period in which we read the agreement; the disclosure statement alone can run to hundreds of pages. Freehold pre-construction homes have no statutory cooling-off period.

What the disclosure statement tells you

Deposits and the builder's licence

Deposit schedules in pre-construction are long and large. Confirm that the builder is licensed by the HCRA and the project enrolled with Tarion, because Tarion's deposit protection and the Act's trust requirements only help you if they are. The Tarion addendum attached to the agreement sets the critical dates and the compensation for delay, and it cannot be waived.

Interim occupancy

You may be required to move in before the condominium is registered. During that period you pay a monthly occupancy fee, capped by section 80(4) at interest on the unpaid balance, an estimate of taxes and the projected common expenses. You do not own the unit yet, cannot register a mortgage on it and may be restricted from renting it. Final closing comes after registration, which can be months later.
