How a Property Tax Sale Works in Canada — and How to Stop One
Many homeowners are surprised to learn that unpaid municipal property taxes can cost them their home — even when the mortgage is completely current. A property tax sale is a legal process a municipality can use to recover taxes it is owed. The good news: it moves slowly, it gives you clear windows to act, and home equity can usually fund the payment that stops it. Here is how it works.
This article is general information, not legal advice. Tax sale rules and timelines vary by province and municipality — confirm the details for your property with your municipality or a licensed professional.
Why unpaid property taxes are so serious
Property taxes are not like an ordinary bill. In most of Canada, municipal tax arrears take priority over your mortgage — they sit ahead of your lender’s claim on the property. That is why mortgage lenders watch tax arrears closely, and why unpaid taxes can jeopardize your financing as well as your ownership. Resolving them protects both your home and your mortgage.
The property tax sale process, step by step
While the exact rules differ by province (Ontario’s process under the Municipal Act, 2001 is a common reference point), the general path looks like this:
- Arrears accumulate. Unpaid taxes attract monthly penalties and interest that add up quickly, on top of the original amount owed.
- A tax arrears certificate is registered. After taxes have been unpaid for a set statutory period — roughly two years in Ontario — the municipality registers a certificate on the property’s title. This is the formal warning that the property will be sold if the arrears are not cleared.
- The redemption period begins. Once the certificate is registered, you generally have about one year to pay the “cancellation price” — all the taxes, penalties, interest and costs owed — and cancel the sale.
- The tax sale. If the arrears are not paid within the redemption period, the municipality can sell the property to recover what it is owed, typically by public tender or auction. In Ontario, once a tax deed is registered after the redemption period, there is generally no further right to redeem.
The key takeaway: there is a built-in window — often a year or more — but it closes on a hard deadline. Acting inside that window is everything.
What a tax sale actually costs you
Beyond the original taxes, you accumulate monthly penalties and interest plus legal and administrative costs. Clearing the arrears with lower-cost mortgage financing usually saves money compared with letting penalties keep compounding — and it removes the risk to your home entirely.
How to stop a property tax sale
There are two ways to stop the process before the deadline:
Pay the cancellation amount in full. This cancels the certificate and the pending sale.
Finance the payment with your home equity. A refinance or second mortgage can pay the municipality directly and roll the arrears into a single, manageable payment. Because approval is based on your equity rather than your credit score, bruised credit or past arrears do not automatically disqualify you. Private and alternative financing can fund in as little as 24 to 72 hours — often well inside the redemption window.
Many homeowners also choose to include property taxes in their new mortgage payment going forward, so they never fall behind again.
Don’t confuse a tax sale with a CRA debt
A municipal property tax sale is different from a debt owed to the Canada Revenue Agency. If you owe income tax or have a CRA lien on your home, the process and your options differ — see our guide on clearing CRA debt with home equity.
What to do today
- Read any notice from your municipality and find the redemption deadline.
- Total the cancellation amount (taxes + penalties + interest + costs).
- Compare that to your available equity — a quick review tells you whether financing can clear it in time.
