Quick Answer Summary
A Canadian tax sale is a legal process where a municipality auctions a property to recover unpaid property taxes. When taxes remain unpaid for 2 to 3 years, the local government seizes the property and sells it via public auction or sealed tender. The winning bid must meet a minimum tender amount, which covers only the outstanding taxes and fees, allowing investors to purchase real estate significantly below market value, subject to provincial redemption periods.
What is a Tax Sale?
Key insight: The minimum bid is typically only the amount of unpaid taxes plus fees — not the property's market value. This is why discounts of 50-80% are common.
How Tax Sales Work in Canada
Each province administers tax sales differently, but the general process follows six steps:
Tax Arrears Accumulate
Property owner fails to pay taxes for 2-3+ years.
Notice to Owner
Municipality sends warnings and a final notice of intent to sell.
Public Advertisement
Sale is advertised in local newspapers and/or online.
Sale Event
Property sold via tender (sealed bid) or public auction.
Redemption Period varies by province
Original owner may reclaim the property by paying all arrears + interest.
Title Transfer
After redemption period expires, buyer receives clear title.
Tender vs Auction
Canadian tax sales use two formats. Understanding the difference is crucial for your bidding strategy.
Tender
Sealed bid submitted by deadline. Highest bid wins. Common in Ontario.
Auction
Live bidding, price goes up. Common in Alberta and BC.
For a detailed comparison, see our Tender vs Auction guide.
Redemption Periods by Province
After a tax sale, most provinces give the original owner a window to reclaim the property by paying all outstanding taxes, interest, and fees. This is the redemption period.
| Province | Redemption Period | Sale Format |
|---|---|---|
| Ontario | 1 year | Tender |
| British Columbia | 1 year | Auction |
| Alberta | None | Auction |
| Manitoba | 1 year | Auction |
| Saskatchewan | 6 months | Tender |
| Quebec | 1 year | Auction |
| Nova Scotia | 6 months | Both |
| New Brunswick | 6 months | Auction |
| Prince Edward Island | None | Tender |
| Newfoundland & Labrador | Varies | Auction |
| Northwest Territories | 1 year | Auction |
| Yukon | 1 year | Auction |
| Nunavut | None | Auction |
Alberta note: Alberta has no redemption period — title transfers immediately after the sale. This makes Alberta especially attractive for investors who want certainty.
Due Diligence Checklist
Before bidding on any tax sale property, thorough research is essential:
Title Search
Verify ownership, liens, and encumbrances
Property Inspection
Drive by — assess exterior and neighbourhood
Zoning Verification
Confirm classification and planned changes
Environmental Check
Contamination risks for commercial sites
Tax Arrears
Verify exact amount owing + penalties
Market Comparables
Research recent sales to set your max bid
Use our Due Diligence Checklist tool to track your research for each property.
Common Risks
Tax sales carry real risks every buyer should understand:
Redemption Risk
Original owner may reclaim the property — you only recover your purchase price plus interest.
Unknown Condition
Sold 'as-is' with no warranties. No interior inspections before purchase.
Occupant Issues
Property may be occupied. Eviction can be costly and time-consuming.
Surviving Liens
Federal tax liens and some utility charges may survive the sale.

Who Invests in Tax Sales?
Tax sale investing attracts several distinct types of buyers, each with different goals and strategies. Understanding which category fits your situation helps you approach the market effectively.
Fix & Flip Investor
Buys distressed properties below market value, renovates, and sells for profit within 12–24 months. Tax sales are ideal because the margin between the winning bid and market value often absorbs significant renovation costs while still generating returns.
Buy & Hold / Rental Investor
Acquires properties at below-market prices and holds them as rental income generators. The low purchase price creates a built-in cost advantage that makes cash-on-cash returns significantly better than traditional purchases.
Other common investor types include land bankers (buying vacant land in tax sales and holding for future development), redemption investors (treating the bid as a secured investment — they earn 10% interest if the property is redeemed in Ontario), and personal use buyers who want affordable housing or vacation properties.
Advanced Bidding Strategies
Winning at tax sales requires more than just money. Successful investors use a systematic approach to identify, research, and price their bids.
1. Build a Comparable Analysis (CMA)
Before bidding on any property, build a comparable market analysis using recent sales data from your province's land registry. Identify 3–5 similar properties sold within 2km in the last 12 months. Your maximum bid should be this CMA value minus: estimated repairs, closing costs, holding costs, and your required profit margin. This gives you a data-driven maximum bid ceiling.
2. Calculate Your All-In Cost
Many first-time tax sale buyers focus only on the bid price. Your true all-in cost includes the bid, land transfer tax, legal fees, title insurance, due diligence costs, and holding costs during the redemption period. A property that looks cheap at $40,000 can cost $52,000+ all-in. Model out all scenarios before bidding.
3. Attend Auctions to Learn Before You Bid
Most provincial tax sale auctions are open to the public. Attend one or two auctions in your target area before bidding yourself. Observe the competition level, the ratio of properties sold vs. passed, and the relationship between winning bids and assessed values. This intelligence dramatically improves your strategy for your first active bid.
4. Bid on Multiple Properties Simultaneously
Most tax sale auctions for a given municipality include multiple properties. Research several at once and prepare bids for all of them. Not all will go to the winning bid you planned — having multiple strategy targets increases your probability of winning at least one.
5. Use the Redemption Period Productively
While you're waiting out the redemption period, you can be productive: obtain a surveyor's report, contact the municipality about any open permits or by-law violations, consult with lenders about what financing will be available after you take title, and develop your renovation plan. Being ready to move the day redemption expires saves months.
6. Understand the Cancellation Price vs. Market Value Gap
In Ontario, the minimum bid is the 'cancellation price' — the total taxes owed plus all fees. A property assessed at $400,000 may have only $18,000 in tax arrears, creating a theoretical maximum discount of 95%+. Competitive bidding will erode this, but researching the ratio of cancellation price to assessed value is your most powerful screening tool.
Complete Cost Breakdown
The true cost of a tax sale purchase extends far beyond the winning bid. Here is a comprehensive breakdown of every cost category you should budget for:
| Cost Category | Typical Range | Notes |
|---|---|---|
| Winning bid | Varies | Minimum = cancellation price (taxes owed + fees) |
| Deposit (ON) | 20% of bid | Must accompany sealed tender. Returned if not winner. |
| Land transfer tax | $800–$10,000+ | Provincial rate on purchase price. ON has additional municipal LTT. |
| Title search | $300–$800 | Essential before bidding. Reveals encumbrances. |
| Legal fees (closing) | $1,500–$3,500 | Tax deed registration, title review, closing. |
| Title insurance | $200–$600 | Owner's policy recommended for tax sale properties. |
| Phase I ESA (if commercial/industrial) | $2,000–$5,000 | Environmental site assessment. Required for non-residential. |
| Property tax during redemption | $500–$5,000/yr | You become responsible for ongoing taxes after winning. |
| Insurance during redemption | $500–$2,000/yr | Vacancy insurance required — standard policies don't cover vacant properties. |
| Utilities / winterizing | $200–$2,000 | Securing vacant property, preventing water/freeze damage. |
| Renovation / repairs | $0–$200,000+ | Highly variable. Budget conservatively — interior access not available before purchase. |
| Total Holding Cost Buffer | 10–20% of bid | Add this as a minimum contingency to any bid calculation. |
Tax Implications of Tax Sale Purchases
Purchasing a tax sale property has several tax consequences most buyers overlook:
GST/HST on Tax Sale Properties
GST (5%) or HST (13–15% depending on province) may apply to your purchase. If the property has been newly constructed, substantially renovated, or is a commercial property, HST is nearly always applicable. It is the buyer's responsibility to determine GST/HST status and remit to the CRA if required — municipalities generally do not collect or remit HST on your behalf. See our complete HST on Tax Sales guide for detailed analysis.
Land Transfer Tax
Every province has a land transfer tax (LTT) payable on the purchase price. Ontario has the highest combined LTT rate (provincial + Toronto municipal), while Alberta and Saskatchewan have no provincial land transfer tax at all. LTT is calculated on your winning bid price, not the market value.
Capital Gains on Resale
When you sell a tax sale property you purchased as an investment, the profit is taxable as a capital gain (50% inclusion rate in Canada as of 2024 — note that 2024 budget proposed 66.7% for gains over $250,000). If you operate as a business (frequent flipping), CRA may reclassify gains as business income (100% taxable). Consult a tax professional before your first sale.
HST on Rental Income
If you hold the tax sale property as a long-term residential rental, rental income is generally exempt from HST. If you operate short-term rentals (Airbnb, VRBO) with stays under 30 consecutive days, HST registration and collection becomes mandatory once annual revenue exceeds $30,000.
Legal Framework: Key Legislation
Tax sale investing is governed by provincial statutes. Familiarity with your province's governing Act is essential for understanding your rights, obligations, and risks as a buyer.
