Property tax arrears on an Ontario home do not prevent a sale, but they do affect how the sale proceeds are distributed at closing, and they create a specific and time-sensitive risk if left unresolved. Homeowners who have fallen behind on property taxes in Ontario face the possibility of a municipal tax sale if arrears remain unpaid long enough. Acting before that process reaches its final stages protects significantly more equity than waiting.

How Property Tax Arrears Work in Ontario
Under Ontario’s Municipal Act, 2001, municipalities can register a tax arrears certificate on a property when taxes have been overdue for a specified period. Once registered, the homeowner has a prescribed redemption period to pay off the arrears in full. If the arrears are not paid within that period, the municipality can proceed with a tax sale, selling the property to recover the tax debt. The homeowner receives any proceeds above the tax arrears, penalties, and sale costs. The process can take 12 to 24 months from initial registration to completed tax sale, but once the final stages are reached, the homeowner’s ability to control the outcome disappears.
Ontario municipalities charge interest and penalties on overdue property taxes, typically at 1.25% per month (15% annually). The longer arrears go unpaid, the larger the lien grows. Early action is almost always financially better than waiting.
Can You Sell a House with Property Tax Arrears in Ontario?
Yes. A property with outstanding property tax arrears can be listed and sold through any method at any point before the municipality completes a tax sale. The arrears are registered as a lien on the property title and will be paid from the sale proceeds at closing, along with any accumulated penalties and interest. The seller does not arrange this payment separately. The lawyer handles it as part of the standard closing process.
How Tax Arrears Are Handled at Closing
When the sale closes, your real estate lawyer prepares a closing statement that accounts for all amounts owing on the property title. This includes the mortgage balance (if any), property tax arrears and accumulated penalties, any other registered liens, and legal fees. All of these are paid from the purchase price before you receive the net proceeds. If the total of all payouts is less than the purchase price, the remainder goes to you. If the total exceeds the purchase price, you receive nothing and may owe the difference. In most cases where the homeowner has owned the property for a significant period, property appreciation provides equity above the total debt.
What If the Tax Arrears Are Substantial?
If you have significant tax arrears accumulated over multiple years, the first step is to get an accurate statement from your municipality showing the total amount owing including penalties and interest. Compare this against a realistic assessment of your property’s current market value. If equity remains above the total debt, a sale is financially viable and you will receive net proceeds. If the numbers are close, a cash buyer who can close quickly cuts off the accumulation of additional daily and monthly penalties.
Why Acting Quickly Reduces the Total Cost
Every month that property tax arrears remain unpaid, additional penalties and interest are added to the lien. A property with $15,000 in arrears today will have a materially larger lien 12 months from now. Beyond the growing lien, once a municipality registers a tax arrears certificate, the redemption period clock starts. Selling before the final stages of a tax sale is almost always possible, but acting early leaves more of the equity in your hands.

The Risk of Waiting: Ontario Tax Sales
If property tax arrears are not resolved and the municipality proceeds with a tax sale to completion, the homeowner receives only the surplus above the tax debt and sale costs. In some cases there is no surplus. Selling privately before this stage, even to a cash buyer at a price below full market value, is almost always a better outcome. If you have received any notice from your municipality about tax arrears, contact a real estate lawyer and consider your options immediately.
