Can I Sell My House in Ontario If I Owe Money on a Lien or Unpaid Property Taxes?

TSL Written by the Treadstone Law Team· Updated November 1, 2026

Whether you can sell depends on what is registered against your home and how much is owing. Unpaid property taxes are a special lien on the land that ranks ahead of every other claim except the Crown's. If arrears are still owing on January 1 in the second year after they became owing, the treasurer may register a tax arrears certificate on title.

The CRA can certify an unpaid tax debt, and a registered memorial of it creates a charge ranking behind interests perfected before it was recorded. A writ of execution binds the debtor's lands from its effective date noted in the sheriff's index. A contractor's lien is preserved by registering a claim on title, then expires unless perfected within 90 days. Anyone can search property records on OnLand for a fee.

Before the one-year period under the Municipal Act, 2001 ends, a tax arrears certificate can be cancelled by paying the cancellation price, which covers arrears, current taxes, interest, penalties and reasonable municipal costs. For a construction lien, a court must make an order vacating it when money or security is paid into court. Because each claim works differently, a lawyer can confirm what must be paid and how at closing.

Key takeaways

  • Unpaid property taxes are a special lien on the land that ranks ahead of every other claim except the Crown's.
  • A tax arrears certificate can be cancelled before the one-year period ends by paying the cancellation price.
  • CRA debts, writs of execution and construction liens can each end up registered against your property, and anyone can search property records on OnLand for a fee.
  • A court must make an order vacating a construction lien when money or security is paid into court.
