Two Ontario closing-cost deadlines catch buyers who assume they have forever: the Ontario land transfer tax refund for first-time buyers must be filed within 18 months of registration, and a purchaser of a new Toronto condo unit has a statutory right to rescind the agreement within 10 days under the Condominium Act โ a right that expires long before closing, not at closing.
The first-time buyer refund has an 18-month filing deadline
Ontario's land transfer tax refund for first-time homebuyers isn't automatic at closing in every transaction, and it isn't open-ended: the province's own page states the application deadline is 18 months after the date the transfer is registered (or the disposition occurs). A buyer who registers in Toronto and later realizes their lawyer didn't apply the refund at closing still has a real, but time-limited, window to claim it โ 18 months, not indefinitely.
The deadline applies to the provincial refund only. Toronto runs a separate first-time buyer rebate against its own Municipal Land Transfer Tax, which mirrors Ontario's brackets up to C$2,000,000 and follows its own rebate program with its own cap, so a missed refund at closing can mean two separate applications, each governed by the level of government that levied that portion of the tax โ a point the bracket math itself, laid out on Ontario's own calculation page, does not address.
Buying a new Toronto condo unit: a 10-day right to walk away, separate from closing
For a new condominium unit bought from a declarant (developer), Ontario's Condominium Act gives the purchaser a statutory right to rescind the agreement of purchase and sale before accepting a deed. Written notice of rescission must reach the declarant or its solicitor within 10 days of the latest of: receiving the disclosure statement, receiving the condominium guide, or receiving the agreement executed by both parties. This window closes early in the process โ often years before the closing-cost figures on this page ever come into play โ and it is separate from any land transfer tax or MLTT deadline.
If rescission is exercised in time, the Act requires the declarant to promptly refund all money received, without penalty or charge, plus interest at the prescribed rate. That protection applies to new units from a declarant only โ it does not apply to a resale condo purchase, which has no equivalent statutory cooling-off period under this Act.
Methodology
Deadlines are stated exactly as published by the Government of Ontario and, for the rescission right, as set out in the Condominium Act, 1998 itself; the worked example applies the same Ontario/Toronto MLTT bracket math used elsewhere on this page to a single deadline scenario.
