Canadian Tax Sale Rules
A tax sale in Canada occurs when a municipality publicly sells a private property to recover unpaid property taxes. The process, format (sealed tender vs. live auction), and redemption periods are strictly regulated by provincial legislation, such as the Ontario Municipal Act. Buyers acquire the property "as is," assuming specific surviving liens.

Provinces Compared
The rules governing a tax sale property are entirely dependent on the province where the real estate is located. Below is the definitive comparison of tax sale formats and redemption periods across key Canadian provinces.
| Province | Sale Format | Redemption Period | Governing Legislation |
|---|---|---|---|
| Ontario | Public Tender (Sealed Bids) | 1 Year | Municipal Act, 2001 |
| Alberta | Live Public Auction | No Redemption Period | Municipal Government Act |
| British Columbia | Live Public Auction | 1 Year | Local Government Act |
| Nova Scotia | Live Public Auction | 6 Months (if taxes owed > 6 years) | Municipal Government Act |
| Saskatchewan | Live Public Auction | 6 Months | Tax Enforcement Act |
Core Definitions
To accurately understand Canadian municipal tax sales, you must understand the following core terminology:
- Minimum Tender Amount: The lowest acceptable offer for a tax sale property. It is mathematically calculated by combining all historical unpaid property taxes, accumulated interest, municipal penalties, and the exact legal costs incurred by the municipality to execute the tax sale proceedings.
- Redemption Period: A legally mandated window of time following a tax sale during which the original delinquent property owner retains the right to reclaim their title. To execute a redemption, the owner must pay the entire tax arrears, all penalties, and the municipality's costs. During this period, the winning bidder cannot develop or alter the property.
- Public Tender: A specific tax sale format, mandated in Ontario, where prospective buyers submit their best and final offer in a sealed envelope, accompanied by a certified deposit (usually 20%). Bids are opened simultaneously, and the highest eligible bid wins.
- Live Public Auction: An open bidding event where attendees verbally submit increasing offers until no higher bids are made. This format is the standard for Alberta and British Columbia.
- Surviving Liens: When a property undergoes a tax sale, most mortgages and private debts are wiped clean from title. However, specific "Crown Interests" (debts owed to the provincial or federal government) automatically survive the sale and become the responsibility of the new buyer.
