Ontario Senior Homeowners' Property Tax Grant: Eligibility and How to Claim

Most seniors in Ontario know about the Trillium benefit but overlook the Ontario Senior Homeowners' Property Tax Grant (OSHPTG) — a separate grant worth up to $500 per year. For surviving spouses managing property taxes on a fixed income after losing a partner, this grant is often one of the first programs to lapse because no one flagged it during estate administration.

What the OSHPTG Is

The OSHPTG is an annual grant paid by the Ontario government to eligible senior homeowners. It is designed to reduce the property tax burden for lower-income seniors who own and live in their principal residence.

The maximum grant is $500 per year. It is claimed by completing the ON-BEN application with your annual Ontario personal income tax return. It is normally paid 4–8 weeks after the Canada Revenue Agency sends your notice of assessment.

OSHPTG Eligibility Requirements

To qualify for the grant in a given year, you must meet all of the following:

Age: You must have been at least 64 years old on December 31 of the prior tax year. (That means to claim the grant for 2026, you must have turned 64 by December 31, 2025.)

Residency: You must be a resident of Ontario for income tax purposes.

Homeownership: You must own and occupy a principal residence in Ontario. The property must be your primary home, not a rental, cottage, or secondary property.

Income limit: For a single applicant, the full $500 grant is available if adjusted family net income is $35,000 or less, and the grant phases out between $35,000 and $50,000. For a married or common-law couple, the full grant is available if combined income is $45,000 or less, and it phases out between $45,000 and $60,000.

Property tax paid: You must have paid Ontario property tax on your principal residence for the year.

How to Claim the OSHPTG

The OSHPTG is claimed by completing the ON-BEN application that accompanies your Ontario tax return. If you file electronically, tax software will prompt you through the relevant screens; for a paper return, complete the ON-BEN form with the return.

You do not send a separate application directly to Ontario — the ON-BEN claim flows through your annual income tax return and the CRA processes it.

The grant is normally paid 4–8 weeks after the CRA sends your notice of assessment, rather than on the Ontario Trillium Benefit's monthly payment schedule.

What Changes After a Spouse Dies

This is where most surviving spouses run into trouble. When a couple's eligibility was calculated using combined income, the switch to single status after death can make the surviving spouse newly eligible for the OSHPTG — even if they were not eligible before.

Here is why: while your partner was alive, your combined family net income may have exceeded the $50,000 phase-out threshold. After the death, your household income drops to your income alone. If that drops below $50,000 — and especially if it drops below $35,000 — you may now qualify for the full $500 grant.

To trigger this eligibility change, you must:

1. File your Ontario personal income tax return for the year of death, noting your change in marital status as of the date of death.
2. In subsequent years, ensure your T1 return reflects your new status as a widowed person, not a married or common-law partner.
3. Complete the ON-BEN application on each return and answer the property tax questions accurately.

If you have been on a property tax deferral program through your municipality (such as those offered in Ottawa, Guelph, or Vaughan), the OSHPTG can be claimed independently — the provincial grant and the municipal deferral are separate programs and do not cancel each other out.

How the Grant Interacts With Other Property Tax Programs

Ontario offers several layered programs for senior homeowners. Understanding how they stack:

Ontario Property Tax Credit (part of Trillium): A separate credit based on property tax paid, also claimed through the Ontario Trillium Benefit. This is calculated separately from the OSHPTG and can be received alongside it.

Municipal deferral programs: Cities like Ottawa, Guelph, and Vaughan allow eligible seniors to defer property tax increases or the full amount. These are not provincial programs — you apply directly to your municipality. Deferral of tax is not the same as reduction; deferred amounts typically become due when the home is sold.

Ontario Land Transfer Tax Refund: A separate program, applicable when purchasing a home, not for ongoing property ownership.

OSHPTG specifically targets homeowners: Renters do not qualify. If a surviving spouse transitions from homeownership to renting — for example, after selling the family home to move into a retirement residence — the grant no longer applies.

The Income Threshold After CPP Shock

One frequently missed planning point: surviving spouses often experience what the research calls "CPP shock" — the jarring discovery that the combined CPP survivor pension they receive is substantially less than they expected. The maximum combined CPP retirement and survivor pension for an individual at age 65 is capped at $1,507.65 per month (2026 figures), and many survivors who were already near the CPP maximum receive only a small survivor increment.

This income drop may push many surviving spouses well below the $50,000 income threshold for the first time, making them newly eligible for the full $500 OSHPTG starting with the tax year following the death.

If you are also receiving the Guaranteed Income Supplement (GIS) under OAS — which is available to low-income seniors receiving OAS — your income may be below the OSHPTG threshold, but the grant is not automatic; complete the ON-BEN application with your tax return.

Claim Deadline and Retroactivity

The OSHPTG is claimed on the annual tax return, so the standard CRA deadline applies: April 30 of the following year (or June 15 if you or your spouse have self-employment income). Late returns can be filed, and the CRA allows you to amend prior-year returns up to 10 years back, which means if a surviving spouse missed the OSHPTG in prior years because they were unaware of the program, they may be able to recover those credits retroactively by filing T1 adjustments (Form T1ADJ) for each missed year.

This is a legitimate recovery worth pursuing if income was below $50,000 in those prior years and property taxes were paid on a principal Ontario residence.
