The Ontario Property Tax Arrears Timeline

If you’re behind on property taxes in Ontario, the most useful thing you can understand is the timeline — the sequence from a missed payment to a possible tax sale, and roughly how long each stage lasts. Knowing where you are tells you how much time you have and which options are still open.

This guide lays out the Ontario framework under the Municipal Act, 2001. It’s general information, not legal advice, and the specifics — especially penalty rates and exact timing — vary by municipality, so always confirm with yours. Other provinces have similar but different processes. For the financing side, see our property tax arrears mortgage page.

It starts the moment a tax installment goes unpaid. In Ontario, unpaid municipal taxes are a priority lien on the property — they rank ahead of your mortgage, and nothing has to be registered for that priority to exist. From there, the municipality adds penalty and interest to the balance each month; many Ontario municipalities charge up to about 1.25% per month (roughly 15% a year), though the rate is set locally and varies.

This is the cheapest stage to fix, because no certificate is registered yet and the fastest, lowest-cost financing options are still open. It’s also the stage most people ignore — which is exactly why the balance compounds.

The municipality sends statements and reminders showing the growing balance and warning of enforcement. These aren’t the tax sale itself, but they’re the signal that the process is moving. Treat the first notice as the cue to act, not as something to file away — every month that passes adds penalty and interest and brings the certificate stage closer.

Under the Municipal Act, where taxes remain in arrears for a set period — for most residential land in Ontario, generally about two years — the municipality may register a tax-arrears certificate against the property’s title. This is the formal turning point: the certificate signals the municipality’s intent to sell the property if the arrears aren’t paid, and it opens the redemption period.

Once a certificate is registered, an A-lender is essentially off the table until it’s cleared — but a private lender will still fund on equity with a certificate on title, which is what makes redemption possible at this stage.

Registration of the certificate opens a redemption period — about one year in Ontario — during which paying the full amount owing (the cancellation price: arrears plus penalty, interest and costs) cancels the certificate and stops the process. Partial payments generally don’t redeem the account, so the goal is a zero balance.

This is the window that matters most. Early in it, you may have room for a lower-cost alt-A refinance or an orderly sale; late in it, fast private capital may be the only realistic option. The redemption amount rises over time, so confirm it with the municipality close to when you plan to pay.

If the account isn’t redeemed within the period, the municipality may advertise and conduct a tax sale — typically by public tender or auction — to recover what it’s owed. A tax sale can wipe out the equity you’ve built, because the process is designed to recover the taxes, not to maximize your return. This is the outcome every earlier stage exists to avoid.

Even here, options can remain until the sale actually completes, but they narrow sharply. The lesson of the whole timeline is the same: the earlier you act, the more (and cheaper) your options.

At every stage before a completed sale, if you have equity, a mortgage against your home can fund the payout. Before a certificate, an alt-A refinance where you qualify; after a certificate or near a deadline, a B-lender or private lender that clears the arrears at closing and discharges the certificate.
