In Ontario, a municipality can register a tax arrears certificate against your title once property taxes have gone two calendar years unpaid. From the day that certificate lands, you have one year to pay the balance in full. Not part of it. All of it.
Property tax arrears are municipal property taxes that stayed unpaid past their due date and started collecting penalties and interest. Every province gives municipalities the power to force a sale of the property to recover them, usually somewhere between one and three years of non-payment. The arrears also sit ahead of your mortgage in priority, which is why lenders move fast once they find out.
Most homeowners who reach this point are not careless with money. A business slowed down, a marriage ended, an illness ate a year of income, and the property tax bill became the one payment nobody was actively chasing. What follows is the real timeline in your province, what stops the clock, and how Canadians clear arrears after the bank has already said no. If you have also fallen behind on the mortgage itself, start with our guide on what to do when you are behind on mortgage payments.
What property tax arrears mean in Canada
Unpaid property tax is not a bill that quietly ages in a drawer. It compounds, and it attaches to the land rather than to you personally.
Ontario municipalities charge up to 1.25% per month on unpaid taxes, which works out to 15% a year, and that is the ceiling the Municipal Act, 2001 permits. Most of them charge exactly that. British Columbia sets its arrears interest rate by provincial regulation, and Alberta municipalities set penalties by bylaw. The rates differ. The direction does not.
Why the balance grows faster than people expect
Penalties apply to the tax. Interest then applies to the running total, month after month, and municipalities apply your payments to penalties and interest first, then to the taxes underneath. A $6,000 shortfall from two years ago is rarely $6,000 today. Once a certificate is registered, legal and administrative costs get stacked on top, and those costs form part of what you have to pay to stop the sale.
Tax arrears rank ahead of your mortgage
Municipal tax claims generally take priority over registered mortgages. That has two consequences homeowners feel immediately. Your mortgage lender can pay the arrears itself, add the amount to your loan and charge interest on it, a step lenders call a protective advance. It can also treat the arrears as a default under your mortgage, which puts your renewal at risk even when every mortgage payment has cleared on time. Anyone carrying a second mortgage usually hears from the second lender first, because that lender has the most to lose in a forced sale.
Tax sale timelines across the provinces
Each province runs its own recovery process, and the gaps between them matter more than most homeowners realise. Here are the four largest side by side.
| Province | When the process starts | What gets registered | Your window to pay |
|---|---|---|---|
| Ontario | Taxes unpaid on January 1 of the second year after they became owing | Tax arrears certificate on title | One year from registration, full cancellation price only |
| British Columbia | Taxes still unpaid on December 31, two years after they were imposed, become delinquent | No certificate, the parcel goes to the annual auction list | Until 10 a.m. on the last Monday in September, then one year to redeem after the sale |
| Alberta | Arrears outstanding more than one year, listed by March 31 | Tax recovery notification on the certificate of title | Until March 31 of the following year, then public auction |
| Quebec | Municipality refers the file to the MRC, which runs the auction | Public notice of sale published by the MRC | Until the auction date, then a one-year right of redemption |
Ontario: the year that actually counts
After the treasurer registers the certificate, the property is advertised for public tender if the cancellation price is not paid within one year. That price is everything owing: back taxes, current instalments already billed, penalties, interest and the municipality's costs. Cities including Ottawa and Hamilton publish the same warning, and once the certificate sits on title they cannot accept partial payments unless an extension agreement is signed first. There is no redemption right after the tender closes.
British Columbia: one date, every year
Collectors across B.C. hold the annual tax sale at 10 a.m. on the last Monday in September, a rule set out by the Province of British Columbia. One detail saves homes every autumn: you do not have to clear the whole balance to come off the auction list. Paying the delinquent year, the oldest one, is enough. And if the property does sell, the registered owner keeps a full year to redeem it.
Alberta and Quebec
Alberta municipalities prepare a tax arrears list by March 31 each year, the Registrar of Land Titles registers a tax recovery notification on title, and the parcel goes to public auction with a reserve bid near market value if the arrears are still unpaid by March 31 of the following year, as set out in the province's guide to tax recovery. Alberta also allows a tax agreement of up to three years, which halts the auction while you pay it down. Quebec moves quickest of the four. Under the Municipal Code of Quebec, local municipalities hand the file to the MRC, which sells at annual public auction, and a property sold that way carries a one-year right of redemption.
Five ways to clear the arrears before the sale date
Treat these as a ladder. Start at the top and climb down only as far as your timeline and your credit actually force you to.
- Ask for a payment or extension agreement. Ontario allows extension agreements with the owner, a spouse, a mortgagee or a tenant, and Alberta tax agreements can run up to three years. Ask before a certificate or notification registers, because municipal flexibility drops sharply once it does.
- Pay the oldest year only. In British Columbia that single payment lifts the property off the auction list, which buys you twelve more months to sort out the rest.
- Refinance with your existing lender. This is the cheapest route when it works. It also takes the longest, and it depends on income documents and a credit profile that most people in arrears no longer have.
- Draw on a HELOC or a second mortgage. If you have equity and an existing line, the arrears can be cleared the same week. A registered certificate will complicate a new HELOC application at a bank.
- Use a private mortgage or bridge loan. Equity carries the file rather than income or credit score, the payout goes straight to the municipality at closing, and the timeline is measured in days rather than months.
The mistake that ends most of these files
People wait. They call the municipality, hear that a sale is a year out, and read that as time. It is not time, it is a deadline, and the last sixty days of it are close to worthless because no lender can order a title search, register a new charge and fund inside that window. Honestly, if you are within six months of your redemption date, stop applying to banks and start talking to lenders who fund on equity. The bank's answer will not change. The calendar will. Our breakdown of how much equity you need for a private mortgage is the fastest way to tell whether this route is open to you.
Using home equity to clear property tax arrears
Equity is what makes these files solvable. A homeowner with $12,000 in arrears and $300,000 of equity has a paperwork problem, not a solvency problem, even when three banks have already declined the application.
A private lender underwrites three things here: the equity position, the exit, and the size of the problem being fixed. Tax arrears are one of the cleanest stories a borrower can bring. The money goes straight onto title as a payout, the municipal claim comes off, and the property is worth more to any future lender the day after funding than it was the day before.
What a private lender needs to see
- A current tax statement from the municipality showing the exact payout figure and the registration date of any certificate
- A recent valuation, or an appraisal ordered at application
- Mortgage statements for every existing charge on title
- An exit: a refinance to an A or B lender once the arrears are gone, a sale, or a return to documented income
Loan-to-value drives the rest. The arrears payout is folded into the advance rather than paid separately out of your pocket, and the fees come off the advance at closing. Read our breakdown of private mortgage fees in Canada before you sign anything, so the payout figure and the net advance hold no surprises.
Three errors that cost people the property
- Assuming a partial payment counts. In Ontario, after registration, it does not.
- Shopping A lenders for four months with a certificate already on title.
- Missing the municipality's registered letter because the mailing address on the tax roll is out of date.
Solid Capital is a Canadian alternative lender funding private mortgages and second mortgages for homeowners the banks have turned away. The difference sits in the underwriting: we read the full file, the equity, the tax statement, the income that does not fit a bank's template, instead of stopping at a credit score. A Canadian advisor reviews every file personally. If the equity in your home covers the arrears, there is a real conversation to be had. Talk to a Solid Capital advisor, and there is no impact to your credit to apply. You can also read how our private mortgages work first.
The municipality is not trying to take your house. It wants to be paid, and it will take the money from anyone who brings it. Bring it before the deadline. That is the whole game.
Frequently Asked Questions
How many years of unpaid property taxes trigger a tax sale in Canada?
It depends on the province. Ontario municipalities can register a tax arrears certificate once taxes are two calendar years in arrears, then sell after a further year. British Columbia auctions properties whose taxes became delinquent on December 31, two years after they were imposed. Alberta begins the process once arrears sit more than one year. Some municipalities wait longer than the statutory minimum, but none of them have to.
Can I lose my home to a tax sale if my mortgage payments are current?
Yes. Municipal tax claims rank ahead of registered mortgages, and the recovery process runs independently of your mortgage. In practice most mortgage lenders pay the arrears themselves long before that point, add the amount to your loan, and treat the arrears as a default under the mortgage. That protects the house and damages the mortgage.
Do property tax arrears show up on my credit report?
Municipalities do not usually report property tax arrears to Equifax Canada or TransUnion Canada, so the balance itself rarely appears on your credit file. The registration on title is public, though, and any lender ordering a title search will find it. If your mortgage lender advances the money and you then fall behind on the larger payment, that does reach your credit report.
Can I make partial payments after a tax arrears certificate is registered?
In Ontario, no. Once the certificate is registered the municipality can only accept the full cancellation price, unless you sign an extension agreement first. Those agreements are available to the owner, a spouse, a mortgagee or a tenant, and they have to be in place before the one-year redemption window closes.
Will a bank refinance a home with tax arrears registered on title?
Rarely, and never quickly. A registered tax arrears certificate or tax recovery notification is treated as a defect on title, so most A lenders decline the file or ask you to clear the arrears first, which is the problem you came to solve. Alternative and private lenders fund these files regularly because the payout removes the claim at closing.
How fast can private financing clear property tax arrears?
For approved files, funding often happens within one to two weeks of application, and faster when the appraisal and title search come back quickly. The payout goes directly to the municipality on the closing date. Timelines depend on the province, the state of title, and how quickly the municipal tax statement arrives.
