Ontario Property Tax Deferral: Who Qualifies and How to Apply

If you own your home in Ontario and money is tight, you may be able to postpone paying some or all of your annual property tax increase through a municipal deferral program. Every upper-tier and single-tier municipality in the province is legally required to offer an Ontario property tax deferral for low-income seniors and low-income persons with disabilities, but each city writes its own bylaw. That means income limits, interest rates, application deadlines, and even what portion of your bill you can defer change depending on where you live. The framework comes from Section 319 of the Municipal Act, 2001, which uses the word “shall” — municipalities have to offer something, but the specifics are theirs to set.¹

Because the rules are local, the practical starting point is your own municipality’s tax office. What follows is what you’ll need to know before you call.

Who Qualifies

Low-Income Seniors

The common baseline: you’re at least 65 and receiving the federal Guaranteed Income Supplement.² Several cities open the door wider. Toronto extends eligibility to homeowners over 50 who receive a pension, and to those 60 to 64 receiving GIS or the Spouse’s Allowance under the Old Age Security Act.³ Ottawa allows applicants as young as 55 if they receive a pension.⁴

Low-Income Persons With Disabilities

Most municipalities qualify you if you receive Ontario Disability Support Program benefits.² Some go further. Hamilton also accepts the disability component of the Guaranteed Income Supplement or the Canada Pension Plan Disability Benefit.⁵

Income Limits

Thresholds are all over the map. For 2026, Hamilton caps combined household income at $44,568 for its full tax deferral program.⁵ Ottawa uses $59,397.64, adjusted annually by the Consumer Price Index.⁴ Toronto allows combined household income up to $62,000.³ Richmond Hill splits the test: $23,000 for singles, $40,000 for families.⁶ Income is verified using your most recent CRA Notice of Assessment.

The Property Itself

You must own the home and live in it as your principal residence, and most municipalities require you to have owned it for at least a full year before applying.³ The property has to be in the residential tax class; commercial and industrial don’t qualify.¹ Ottawa also imposes a maximum assessed value of $498,000 for 2026.⁴

What You Can Actually Defer

This trips people up. Section 319 covers “all or part of a tax increase,” not your entire bill.¹ In most cities, that’s the year-over-year jump only. If your taxes went from $4,000 to $4,300, the $300 increase is what you can defer. St. Catharines, for example, defers “any increase in the City portion of property taxes over the previous year.”⁷

A few programs go bigger. Hamilton offers a separate full tax deferral for 2026 that covers the entire bill, with interest at 4.45% compounded annually.⁵ Ottawa’s partial program only kicks in when the tax increase exceeds both $100 and 5% of the prior year’s taxes.⁴ Confirm which version your municipality runs before you assume how much relief is on the table.

How to Apply

Each municipality has its own form, available at the tax office or on the city’s website. Most accept applications by mail, in person, or through a secure online portal. Review usually takes 30 to 60 days while the city verifies your income and ownership, and you receive a decision by letter.

Expect to supply:

Proof of age (birth certificate, passport, or driver’s licence), often only for first-time applicants.
Your most recent Notice of Assessment from the CRA. If you’ve elected pension income splitting, you may also need CRA Form T1032.⁵
Disability documentation if applying on that basis: a monthly ODSP statement from the Ministry of Children, Community and Social Services, or documentation of your CPP Disability Benefit or GIS disability payment.⁶
Your 19-digit property tax roll number, found on your tax bill and your MPAC Property Assessment Notice.⁸

The deferral doesn’t renew automatically. You have to re-apply every year, and the deadlines are unforgiving. Toronto’s deadline for the 2026 tax year is November 2, 2026.³ Ottawa requires renewals by September 30, though first-time applicants have until December 31.⁴ Hamilton gives you until the last day of February of the following year.⁵ Set a calendar reminder.

Interest, Liens, and Total Caps

Deferred taxes don’t sit in limbo. The city secures what it’s owed, and it usually charges interest.

Hamilton registers the deferred balance as a “special lien” on the property, which appears on any tax certificate a buyer or lender pulls.⁵ The lien doesn’t force a sale on its own, but it has to be cleared at any transfer.

Interest rates run from nothing to 5%. Hamilton charges no interest on its tax-increase deferral while you stay eligible, but 4.45% compounded annually on its full tax deferral.⁵ Ottawa charges 5% per year on all deferred amounts.⁴ That interest reduces the equity you or your heirs eventually collect.

Some municipalities cap how much you can defer in total. Hamilton limits accumulated deferrals to 40% of assessed value.⁵ Ottawa allows arrears up to 20% of the current value assessment.⁴ Once you hit the cap, no more deferrals — you pay the full amount going forward.

When the Bill Comes Due

The deferred amount becomes payable when you sell or transfer the property, stop using it as your principal residence, or no longer meet the eligibility rules. On a sale, the lien is settled from the proceeds at closing.

At death, the outcome depends on the local bylaw. In Hamilton, if the surviving spouse still meets every eligibility criterion, the deferral can continue. Otherwise the balance plus interest generally comes out of the estate. If you’re inheriting a home you know participated in a deferral program, pull a tax certificate and title search before deciding whether to keep or sell.

False statements on an application aren’t a small matter. Toronto disqualifies the property from any deferral, cancellation, or rebate for the year, requires full repayment, and charges interest at 1.25% per month retroactive to the original deferral date.³

Check With Your Mortgage Lender First

If your lender escrows property taxes as part of your monthly payment, deferring can create conflict with your mortgage agreement. Call your mortgage servicer before you apply.

Reverse mortgages need extra care. Those agreements typically require you to stay current on property taxes, and lenders may not treat a municipal deferral the same way the municipality does. Get written confirmation from your reverse mortgage lender that participating in the deferral program won’t be treated as a tax default.

Deferral Is Not the Same as Cancellation or Rebate

Ontario municipalities usually offer three kinds of property tax relief, and confusing them can cost you real money. A cancellation reduces or eliminates part of your bill and never has to be repaid. A rebate reimburses you after you’ve paid. A deferral only delays payment; the full amount plus any interest eventually comes due.

Many cities bundle these on one application. Toronto runs its deferral alongside a cancellation and a water and solid waste rebate under one relief program.³ If you qualify for cancellation, that’s almost always the better outcome, because the reduction is permanent. A deferral is the right tool when cash flow is the problem now and you expect to clear the balance later, typically from the sale of the home. Ask your municipal tax office which programs you qualify for before settling on a deferral by itself.
