Key Ontario Senior Credits & Benefits
1. Senior Homeowners' Property Tax Grant
- Eligibility: Ontario residents aged 64 or older (as of December 31 of previous year) who owned and occupied their principal residence in Ontario, paid property tax, and meet income requirements (grant is phased out above $50,000 for singles, $60,000 for couples).
- How much? Up to $500 per year (reduced for higher-income seniors). Example: A 72-year-old single homeowner with $35,000 income and $2,100 property tax paid will get the full $500.
- How to claim: Complete the ON-BEN Application (included with your personal income tax return). You must enter your property tax amount for the previous year. The credit is paid as a lump sum, usually in July.
- Documentation: Keep your property tax bill, proof of payment, and documents showing you owned and lived in the home (utility bill, driver's license, etc.).
- Calculation example:
Mrs. D, age 68, owns her home, paid $2,600 in property taxes, and has $32,000 income. She claims the grant on her 2025 tax return. She will receive $500 in July 2026.
2. Ontario Seniors' Public Transit Tax Credit
- Eligibility: Ontario residents aged 65+ (or turning 65 by year-end), regardless of income. Applies to public transit fares purchased for yourself.
- How much? Refundable credit of 15% of eligible Ontario transit costs, up to $3,000 per year (maximum $450 credit per individual). Example: $1,200 spent on transit = $180 credit.
- How to claim: Complete the Ontario section of your personal tax return. Enter eligible transit amounts—includes monthly/annual passes, PRESTO cards, ride cards for city buses, subway, regional rail (GO Transit), and eligible community transit.
- Documentation: Save all receipts, passes, PRESTO transaction history, and fare payment records for audit.
- Calculation example:
Mr. F, age 70, buys a $120 monthly transit pass for 10 months: $1,200 x 15% = $180 refundable credit.
3. GAINS (Guaranteed Annual Income System)
- Eligibility: Low-income Ontario seniors receiving Old Age Security (OAS) and the Guaranteed Income Supplement (GIS). No separate application—CRA and Ontario automatically assess eligibility based on your tax return.
- How much? Monthly top-up, up to $83 per month for singles, $168 per couple (2025 rates, subject to change). Phased out at higher incomes.
- How to claim: File your annual tax return and ensure you receive OAS/GIS. Ontario will notify you by letter if you qualify.
- Documentation: Keep your OAS/GIS statements, GAINS award letter, and tax return copies.
- Scenario:
Ms. B, age 75, receives OAS/GIS and has $13,000 total income. She is automatically enrolled in GAINS and receives $68/month in top-up payments from Ontario.
4. Ontario Energy and Property Tax Credit for Seniors
- Eligibility: Ontario residents aged 65+ (or with a spouse aged 65+), who paid property tax, rent, or resided in a care home. Income-tested (phase-out at higher incomes).
- How much? Maximum of $1,429 per year for seniors (2025 rate; indexed). Example: A senior renter with $28,000 income and $900/month rent may qualify for the full credit.
- How to claim: File the ON-BEN Application on your tax return. Enter your property tax, rent, or accommodation costs. The credit is paid monthly via the Ontario Trillium Benefit.
- Documentation: Rent receipts, property tax bills, care home statements.
- Scenario:
Mr. G, age 67, rents an apartment for $1,100/month, income $29,500. He claims this credit and receives $1,100/year Trillium payments.
5. Other Ontario Senior Supports
- Home Accessibility Tax Credit (federal): Up to $20,000 in eligible home renovation expenses for seniors/disabled persons (claimed federally, applies to Ontario seniors).
- Medical Expense Tax Credits: Both Ontario and federal portions—claim eligible unreimbursed medical expenses for yourself and your spouse/partner.
- Ontario Drug Benefit (ODB): Prescription coverage for Ontarians 65+, with copayment and deductible based on income.
- Property tax deferral: Many municipalities offer property tax deferral/relief for low-income seniors. Check your city/town for application details.

Audit Risk, Common Errors & Documentation Best Practices
- Common audit triggers: Large or unusual rent/property tax claims, switching from homeowner to renter mid-year, or duplicate claims by spouses.
- Common errors: Claiming full rent when sharing with roommates, not prorating for moves, claiming both rent and property tax for same period, or missing supporting receipts.
- Best practices: Keep all rent receipts, property tax bills, transit pass receipts, OAS/GIS/GAINS letters, and care home statements for at least 6 years. Organize by year and claim type. If you move, keep documentation for all addresses/care homes.
- Responding to audits: Reply to CRA/Ministry requests quickly, attach digital scans/copies, and call for clarification if unsure. If your documentation is incomplete, provide as much proof as possible and a written explanation.
- Pro tip: Use a file folder or digital folder labeled by year. Ask for receipts from day one, and keep a summary sheet for each credit you claim.

Frequently Asked Questions
Do I need to apply separately for GAINS?
No. If you receive OAS/GIS and file your Ontario tax return, you are automatically considered for GAINS. There is no separate application required; you will be notified by mail if you qualify.
Is the Ontario Seniors' Public Transit Tax Credit income-tested?
No. All Ontario residents 65+ can claim 15% of eligible transit costs, regardless of income. You must keep receipts for audit purposes.
Can I claim both property tax and rent for senior credits?
No. You may only claim one (property tax if you own, rent if you rent) per principal residence per year for the OEPTC and Property Tax Grant.
What if my spouse is under 65?
If you are 65+ and your spouse is under 65, you may still qualify for senior-specific credits if you are the primary applicant and meet all other conditions. For some credits, a spouse's age may increase the household maximum.
How long should I keep supporting documents for these credits?
Keep all receipts, tax bills, and proof of payment for at least 6 years, as CRA/Canada Revenue Agency or Ontario Ministry of Finance may request them for verification.
Can I receive both GAINS and the federal GIS?
Yes. GAINS is a provincial top-up to federal OAS/GIS. If you qualify for GIS, you may receive both benefits (subject to income and Ontario residency).
Are there credits for home modifications (e.g., installing a stair lift)?
Yes. The federal Home Accessibility Tax Credit can be used by seniors for eligible renovations up to $20,000 (e.g., ramps, lifts, handrails); Ontario does not have a separate provincial version but recognizes the federal claim.
What if I move mid-year (e.g., from homeowner to care home)?
You may prorate and claim part-year expenses for both residences (property tax and accommodation). Enter details on the ON-BEN form and keep all receipts to support your claim.
Can I claim both the Senior Homeowners' Grant and the OEPTC?
Yes, if eligible, you may receive both. File ON-BEN and the CRA will calculate each based on your age, income, and property tax paid.
What happens if CRA audits my rent or property tax claim?
CRA may ask for receipts, bank statements, or care home invoices. Respond promptly with copies or scans. If a receipt is missing, supply as much proof as possible (e.g., e-Transfers, written landlord statement) and a written explanation.
What if I forgot to claim a senior credit last year?
You can file a T1 Adjustment Request (T1-ADJ) online (via ReFILE or CRA My Account) or by mail to claim missed credits for up to 10 prior years, if eligible. Attach all supporting documentation.
Can I claim senior credits if I rent a room in a relative's house?
Generally, you may claim rent paid to a relative if you have a true landlord-tenant relationship and pay fair market rent. You must have receipts and the relative must report the rental income. CRA may audit these claims closely.
