What actually happens when property taxes go unpaid?
Property taxes don’t behave like a normal debt. Under provincial law, unpaid municipal taxes are a priority lien on your home that generally ranks ahead of every mortgage on title — including your bank’s first charge — and nothing has to be registered for that priority to exist. Each month the balance grows as penalty and interest are added; in many Ontario municipalities that runs up to about 1.25% a month, though the rate varies by municipality.
The process is deliberate, not instant. In Ontario, after taxes have been in arrears for a set period (generally about two years for most residential land), the municipality may register a tax-arrears certificate against your title, which opens a redemption period (about one year) to pay everything owing and stop the process.Municipal Act s.373 Timelines and terminology vary by province and municipality, but the principle is the same: left long enough, a municipality can sell the home to recover what it’s owed. This is general information, not legal advice — confirm your situation with your municipality and a lawyer.
