Tax Sale Property Glossary
Plain-language definitions of key Canadian tax sale terms — from upset price to vente pour défaut de paiement.
Assessed Value
The value placed on a property by the municipal or provincial assessment authority for the purpose of calculating property taxes. Assessed value is typically a percentage of market value and is NOT the minimum bid at a tax sale.
Caveat (Alberta)
A formal notice registered on a property's title in Alberta warning of an interest or claim. Caveats may affect the clear title you receive after a tax sale. Always conduct a title search.
Certificate of Acquisition (Quebec)
The document issued to the winning bidder at a Quebec tax sale ('vente pour défaut de paiement'). The certificate does not constitute clear title until the one-year post-sale redemption period expires without challenge.
Construction Lien
A legal claim registered against a property by a contractor or supplier who performed work or supplied materials and was not paid. Whether construction liens survive a tax sale depends on the province and when the lien was registered relative to the tax sale process.
Crown Mortgage / Crown Charge
A debt owed to the provincial or federal Crown (government) registered against a property. Some Crown charges may survive a tax sale and transfer to the buyer. Examples include unpaid utility fees administered by Crown corporations or environmental remediation orders.
Due Diligence
The process of investigating a property before submitting a bid. Includes: title search, zoning verification, environmental review, road access confirmation, and comparable sales research. Since tax sale buyers often cannot inspect the interior, thorough due diligence is critical.
Encumbrance
Any claim, lien, charge, or liability attached to a property that limits or affects its ownership. Common encumbrances include mortgages, liens, easements, and restrictive covenants. Some encumbrances are extinguished by a tax sale; others survive.
Hardship Application
A request made by a property owner to the municipality to defer or reduce property taxes based on financial hardship. Properties under an active hardship agreement are typically exempt from tax sale proceedings during the approved period.
Legal Description
The formal description of a property's location and boundaries as recorded on the title and in land registry records. A legal description typically includes lot number, concession, plan number, and/or metes and bounds. Required on all tender and deed documents.
Minimum Tender Amount
The Ontario-specific term for upset price. The minimum amount that must be bid to be a qualifying tender. Set by the municipality and published in The Ontario Gazette notice. Bids below this amount are automatically rejected and returned.
Ontario Gazette
The official publication of the Government of Ontario, published weekly. Under the Municipal Act, 2001, all Ontario municipal tax sale tenders must be advertised in The Ontario Gazette. It is the authoritative source for discovering Ontario tax sale listings.
Phase I Environmental Site Assessment (ESA)
A non-invasive study of a property's environmental history to identify potential contamination. A Phase I ESA reviews historical land use, aerial photographs, regulatory databases, and a site visit. Highly recommended before bidding on any commercial or industrial property, or on residential land with previous non-residential use.
Property Identifier (PID / PIN / Roll Number)
A unique identifier assigned to each property within a jurisdiction. Format varies by province: Ontario uses a 9-digit Property Identifier Number (PIN) on land titles; Nova Scotia uses a 8-digit Property Identification Number (PID); other provinces use municipal roll numbers.
Public Auction
A live-bidding tax sale format used in British Columbia, Alberta, Quebec, and Saskatchewan. Interested bidders attend on the auction date and bid openly, with the highest bid above the upset price winning the property on the day.
Public Tender
A sealed-bid tax sale format used in Ontario, Nova Scotia, New Brunswick, and PEI. Interested buyers submit written bids in sealed envelopes by a deadline. All tenders are opened publicly on a set date. The highest qualifying bid wins.
Redemption Period
The period during which the original property owner (or a creditor with a registered interest) can 'redeem' the property by paying all outstanding tax arrears, interest, penalties, and costs. Redemption periods vary by province: Ontario and Nova Scotia allow redemption only until the tender deadline; Quebec grants 1 year after the sale; Alberta and BC grant 1 year before the sale.
Sale of Land for Tax Arrears
The formal legal term for a Canadian municipal tax sale. Used in legislation such as Ontario's Municipal Act, 2001. Triggered when a property owner falls 2+ years behind on property taxes and the municipality decides to exercise its right to sell the property to recover the unpaid taxes.
Tax Arrears
Overdue and unpaid property taxes, including accumulated interest and penalties. When tax arrears reach a threshold (typically 2+ years), a municipality may initiate the legal process leading to a tax sale.
Tax Arrears Certificate
A legal notice registered on a property's title by a municipality in Ontario and some other provinces when taxes are in arrears. Its registration formally begins the tax sale process and triggers the redemption period. If unpaid, it leads to the publication of a public tender notice.
Tax Collector's Deed / Tax Deed
The title document issued by the municipality to the winning bidder of a tax sale, transferring ownership of the property. The Tax Deed extinguishes most prior registered encumbrances (subject to provincial exceptions). In Quebec, the equivalent document is called a Certificate of Acquisition.
Tax Sale
The sale of real property by a Canadian municipality to recover unpaid property taxes. The municipality sells the property via public tender or auction at the 'upset price' (minimum bid). Tax sales offer investors an opportunity to acquire property at below-market prices.
Tender
In the context of Canadian tax sales, a 'tender' is a written bid submitted in a sealed envelope by a prospective buyer. The tender includes the bid amount and a certified deposit cheque. All tenders are opened on the specified date; the highest qualifying bid wins.
Title Search
The process of examining the public land registry records for a property to identify its current ownership, registered encumbrances, liens, rights-of-way, and other interests. A title search is essential before submitting a tax sale bid. Typically costs $100–$300 and is performed by a lawyer or professional title searcher.
Upset Price
The minimum acceptable bid at a Canadian tax sale. Calculated as: all outstanding property tax arrears + accrued interest + penalties + the municipality's legal and administrative costs. The upset price is NOT market value — it is the amount needed to recover the municipality's financial loss. Bids below the upset price are automatically rejected.
Vente pour défaut de paiement (Quebec)
The French-language term for a Quebec municipal tax sale. Translation: 'Sale for failure to pay.' Conducted by the municipal secretary or clerk via public auction. The previous owner has one year after the sale to redeem the property by paying the winning bid price plus 10% annual interest.
Writ of Possession
A court order authorizing the sheriff to remove an occupant from a property and deliver possession to the new owner. May be required after a tax sale if the previous owner or tenant refuses to vacate the property following title transfer.
