How the Ontario tax-sale process works
Under the Municipal Act, 2001, an Ontario municipality can register a tax-arrears certificate where taxes have been in arrears for a set period (generally about two years for most residential land). Registration opens a redemption period — about one year — during which paying the full amount owing (the cancellation price) cancels the certificate.Municipal Act s.373 If the account isn’t redeemed, the municipality may advertise and conduct a tax sale, typically by public tender.
The key point for a homeowner is that the redemption window is your opportunity, and it’s finite. Paying the cancellation price within the redemption period cancels the certificate; once the period ends, the municipality can move to a sale and your options narrow sharply, so ask your municipality in writing what it will still accept. The amount also grows over time. This is general information, not legal advice; confirm your dates and the exact cancellation price with your municipality and a lawyer.
