ReverseMortgageMississauga.ca sets out the Mississauga property tax rebate for seniors, who qualifies, and how to apply before the deadline. It also covers Ontario’s separate grant, and what changes for a homeowner who has a reverse mortgage.
Two programs help Mississauga seniors with property tax. One comes from the City and one from the province, and a homeowner can qualify for both.
Does Mississauga have a property tax rebate for seniors?
Yes. The City of Mississauga gives a yearly property tax rebate to homeowners with low income who are 65 or older, or who have a disability, and who receive the Guaranteed Income Supplement (GIS) or the Ontario Disability Support Program (ODSP). The rebate is credited to your property tax account. You apply by December 31 every year.
Who qualifies
The City’s rules are set out on its rebate page (City of Mississauga) and in its Tax Rebate By-law 0056-2010:
- You or your spouse are 65 or older, or have a disability.
- You receive GIS or ODSP.
- You own your home and have lived in it for at least one year.
- Every co-owner who isn’t your spouse also receives GIS or ODSP.
How much the rebate is
The rebate began at $400 in 2018 and is raised every year (City of Mississauga, Tax Rebate Application Form, April 2026). For this year’s amount, call 311 or email [email protected]. The approved rebate is credited to your property tax account, without interest.
How to apply
Fill in the City’s application form and send it with your documents. You can email it to [email protected], mail it to the City’s tax office, or use the drop box at the Civic Centre. If you receive GIS, include last year’s T4A(OAS) slip.
You must apply every year. The City doesn’t accept applications for past years, so a missed December 31 deadline means that year’s rebate is gone.
Is the stormwater charge covered too?
Yes. If you qualify for the City’s tax rebate, you also qualify for a subsidy that covers 100% of the stormwater charge. There is no separate application. Houses get a credit on the Region of Peel water bill, and condo owners get a cheque from the City (City of Mississauga, stormwater charge).
Can Mississauga seniors defer their property taxes?
No. The City of Mississauga has no current property tax deferral program for seniors, and its tax help pages list the rebate only. A deferral would let you put off the tax bill until later. Without one, the bill is due on the City’s dates, and falling behind adds late-payment interest.
Some homeowners use a reverse mortgage to cover the property tax bill along with other costs. It is a loan, so interest is added to the balance, but there are no required monthly mortgage payments.
What is the Ontario Senior Homeowners’ Property Tax Grant?
Homeowners 64 and older with low to moderate income can also get up to $500 a year from the Ontario Senior Homeowners’ Property Tax Grant. You claim it on your income tax return, on the ON-BEN form. It is separate from the City rebate, so a Mississauga senior can receive both in the same year.
The rules, from the province (Government of Ontario):
- You own and live in your home and paid Ontario property tax.
- A single homeowner gets the full $500 with income up to $35,000, and nothing at $50,000 or more.
- A couple gets the full $500 with income up to $45,000, and nothing at $60,000 or more.
- There is one grant per couple, and it is never paid back.
How does a reverse mortgage affect the rebate and the grant?
A reverse mortgage doesn’t take the rebate or the grant away. Because reverse mortgage money counts as a loan rather than income, there’s no tax on it, and your GIS and Old Age Security stay the same. The rebate depends on GIS or ODSP, and the grant depends on your income, so neither one changes because of what you borrow.
One detail matters. Interest you earn on money left in a savings account counts as income the following year. Monthly amounts that you spend don’t count, so taking the money that way avoids it.
Taxes must stay paid after closing
Property taxes, home insurance and upkeep stay yours with a reverse mortgage. Falling seriously behind on taxes can put the mortgage in default. Some lenders ask for proof each year that the taxes are paid.
Tax arrears are paid off at closing
If you are behind on property taxes when the reverse mortgage closes, the arrears are paid off first, from the reverse mortgage money. Any existing mortgage is paid off the same way. The remaining money is deposited in your bank account. Here is how a reverse mortgage pays off a Mississauga mortgage.
How much did Mississauga property taxes go up in 2026?
Mississauga’s total 2026 residential property tax bill went up 5.21%, and 1.61% of that came from the City’s part of the bill. On a home assessed at $700,000, that is $377.37 more than in 2025. The 2026 rate of 1.087901% makes that home’s full yearly bill about $7,615.
The figures come from the City’s 2026 budget release (City of Mississauga, January 28, 2026) and its 2026 tax rate by-law (By-law 0061-2026). Your assessed value still uses January 1, 2016 values, so it is not what your home would sell for today (MPAC).
The full set of costs that come with a reverse mortgage is in the guide to what a reverse mortgage costs on a Mississauga home. To see a rough amount for your own home, try the Mississauga reverse mortgage calculator.
The bottom line
Mississauga's property tax rebate for seniors is for homeowners 65 and older, or with a disability, who receive GIS or ODSP, and the deadline is December 31 every year. Ontario's grant of up to $500 is claimed separately on your tax return. A reverse mortgage doesn't take either one away, because the money is a loan, not income.
