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, stackable credit 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 a non-refundable 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 on the annual Ontario personal income tax return — the same return where you claim the Ontario Trillium Benefit — and paid out as a lump sum or applied to reduce your tax payable.

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: The full $500 grant is available if your adjusted family net income is $35,000 or less. The grant phases out between $35,000 and $50,000, and disappears entirely above $50,000. If you have a spouse or common-law partner, their income is included in the family net income calculation.

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 on Schedule ON(S12) of your Ontario provincial return, alongside the Ontario Trillium Benefit. If you file a paper return, the form is available from the CRA. If you file electronically, tax software will prompt you through the relevant screens.

You do not apply separately or submit anything to the province — the claim flows through your annual income tax return and CRA processes it.

The grant is paid either as part of your Ontario tax refund or as a direct payment in the year following the filing. If you are on the Ontario Trillium Benefit payment schedule, the OSHPTG payment is typically issued alongside Trillium payments in July of the year after you filed.

What Changes After a Spouse Dies

This is where most surviving spouses run into trouble. When a couple files jointly or calculates benefits based on combined income, the switch to single-filer status after death often makes the surviving spouse newly eligible for the full 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 Schedule ON(S12) 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 is likely already well below the OSHPTG threshold, and you should be claiming the grant automatically through 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.
