How to Calculate Your Property Tax in Ontario (& Lower Your Bill)

Most Ontario homeowners pay thousands in property taxes each year, but few actually understand where that money goes or how the bill is calculated.

Here's the reality: your property tax is based on your home's 2016 assessed value (yes, still 2016) multiplied by your municipality's tax rate. And those rates vary wildly across Ontario, sometimes by more than double.

Whether you're in Toronto or Hamilton, understanding how these taxes work can help you budget better, catch errors in your assessment, and claim rebates you might be missing.

In this guide, you'll learn:

• How Ontario property tax is calculated (MPAC assessed value × combined tax rate)
• 2026 property tax rates for major Ontario cities and why they vary so much
• Payment options, deadlines, and ways to avoid late fees

P.S. — If property tax bills are straining your budget or you've fallen behind on payments, there are practical solutions. Lotly's secured home loans help Ontario homeowners access their equity to clear arrears and consolidate debt, usually within about two weeks. Book a free consultation to see your options.

How property tax works in Ontario

Ontario property taxes fund local services like police, fire protection, transit, schools, and infrastructure. Your annual tax bill comes down to two things: your property's assessed value (set by MPAC) and your municipality's tax rate.

The basic property tax formula

Once you know your assessed value and your city's tax rate, the math is simple.

The formula:

Annual Property Tax = MPAC Assessed Value × (Municipal Tax Rate + Education Tax Rate)

Here's what each piece means:

• MPAC assessed value: Your property's market value as of January 1, 2016, the valuation date currently used across Ontario. This hasn't been updated since 2016, so your tax bill is still based on your home's value from nearly a decade ago.
• Municipal tax rate: Set annually by your local city or town council based on budget needs. This rate varies widely across Ontario. Toronto sits at roughly 0.61%, while Hamilton is closer to 1.33%. Some cities also fold additional levies (such as Toronto's City Building Fund) into their total municipal rate.
• Education tax rate: A fixed provincial rate of 0.153% for residential properties, collected by municipalities and forwarded to the province for public education.

Example calculation:

If your Toronto home has an MPAC assessed value of $700,000:

• Municipal rate (including City Building Fund): 0.6143%
• Education rate: 0.153%
• Combined rate: 0.7673%
• Annual tax: $700,000 × 0.7673% = $5,371

That's your total annual property tax bill, broken into installments throughout the year.

What is MPAC and how does assessment work?

The Municipal Property Assessment Corporation (MPAC) is the provincial agency responsible for determining the assessed value of every property in Ontario. Your MPAC assessment directly affects your tax bill, so it's worth understanding how it's calculated and when it can change. Lotly's guide to property appraisals in Canada covers the broader process in more detail.

Current valuation date: January 1, 2016

Ontario property assessments are still based on 2016 market values. The province originally planned regular four-year reassessment cycles, but the 2016 valuation was frozen, first because of the COVID-19 pandemic in 2020, then extended through regulation in 2023. Your 2026 tax bill still reflects what your home was worth back then, not what it's worth today.

How MPAC assesses your property:

MPAC uses a mass appraisal system that considers up to 200 factors for residential properties. Five of those account for roughly 85% of the value: location, lot dimensions, living area, age of the property (adjusted for renovations or additions), and quality of construction. Things like proximity to transit and neighbourhood desirability also feed into the assessment, though to a lesser degree.

When assessments change:

Even though the valuation date is frozen at 2016, your individual assessment can still change if:

• You complete major renovations or additions (this triggers a reassessment)
• New construction is completed
• Your property class changes (e.g., residential to mixed-use)
• MPAC corrects an error in your property details

Accessing your assessment:

You can check your property's assessed value in three ways: review your annual property tax bill (assessment is listed at the top), visit MPAC's AboutMyProperty portal and enter your address, or check your Property Assessment Notice (mailed by MPAC when changes occur to your property).

The bottom line:

If your home's market value has climbed significantly since 2016, your tax bill is still based on that older assessment, unless you've made major changes to the property. In hot markets where values have surged, this frozen assessment actually works in your favour.

Ontario property tax rates by city (2026)

Property tax rates across Ontario vary widely depending on where you live. A home in Toronto carries a much lower rate than the same property in Hamilton or London, though that doesn't always translate to a lower dollar amount.

Below is a comparison of residential property tax rates for major Ontario cities in 2026, including both the municipal rate and the combined rate (municipal + education). Use this table to see how your city stacks up and estimate your potential tax bill.

Table: 2026 Ontario property tax rates (major cities)

Note: Toronto's 2026 rate reflects the confirmed City Tax Rate (0.6053%) plus the City Building Fund levy (0.0090%). Rates for other cities are based on the most recently available data and may shift once final 2026 budgets are adopted. Municipal tax rates change every year when city councils approve budgets, so always verify your city's current rate before calculating.

What stands out:

Toronto has the lowest rate at roughly 0.77% combined, but higher assessed values mean the actual dollar amount can still be large. A $1 million home in Toronto pays roughly $7,673 annually, which is still less than a $600,000 home in London.

London and Hamilton have the highest rates (1.33%–1.46% municipal). These higher rates reflect larger infrastructure demands and smaller property tax bases relative to city budgets.

Location matters. If you're comparing homes in different cities, run the tax calculation for each one. Don't assume rates are similar across Ontario.

How to calculate your Ontario property tax

Calculating your property tax doesn't take a spreadsheet. You just need your MPAC assessed value and your municipality's tax rate. Here's how to get an accurate estimate in three steps.

Step 1: Find your MPAC assessed value

Your assessed value is what the entire calculation rests on. Here's where to find it:

• Check your most recent property tax bill. Your assessed value is listed at the top, usually labelled "Current Value Assessment" or "CVA."
• Visit MPAC's AboutMyProperty portal. Enter your address to view your property's assessed value, property class, and detailed characteristics.
• Review your Property Assessment Notice. MPAC mails these when changes are made to your property information.
• If you're a buyer: Use the listing price as a rough estimate, but keep in mind that your official MPAC assessment is based on 2016 values, not the current purchase price. Your actual assessment may be significantly lower.

Step 2: Look up your municipality's tax rate

Every Ontario municipality sets its own tax rate annually. Visit your city's website and search for the current year's property tax rate, or check your tax bill, where the rate is usually listed alongside your assessed value. You'll need both the municipal and education rates (0.153% for all Ontario residential properties). Add them together for your combined rate.

Example rates for 2026:

• Toronto: 0.614% (municipal + City Building Fund) + 0.153% (education) = 0.767% combined
• Ottawa: 1.169% (municipal) + 0.153% (education) = 1.322% combined
• Hamilton: 1.327% (municipal) + 0.153% (education) = 1.480% combined

Step 3: Apply the formula

Once you have your assessed value and combined tax rate:

Annual Property Tax = Assessed Value × Combined Tax Rate

Example:

• Assessed value: $650,000
• City: Ottawa
• Combined rate: 1.322%
• Annual tax: $650,000 × 1.322% = $8,593

That's your total annual property tax bill, before any rebates or exemptions.

Pro tip: If you're comparing homes in different cities, run the tax calc for each one. A $700,000 home in Toronto costs roughly $5,371/year in property tax, while the same assessed value in Hamilton costs $10,360. That's nearly $5,000/year in difference.

Property tax rebates and assistance programs in Ontario

If you're a senior, have a disability, or are facing financial hardship, several Ontario programs can help reduce your property tax bill. These rebates and exemptions can save eligible homeowners hundreds of dollars a year, but you do have to apply. For a broader look at federal and provincial programs, see Lotly's complete guide to homeowner grants in Canada.

Ontario Senior Homeowners' Property Tax Grant (OSHPTG)

The OSHPTG is an annual, non-taxable payment for eligible Ontario seniors with low-to-moderate incomes. If you qualify, you can receive up to $500 to offset your property tax costs. No repayment required.

Eligibility:

• Age: You or your spouse must be 64 years or older by December 31 of the previous tax year.
• Residency: You must own and occupy your principal residence in Ontario (or hold a qualifying life lease of 10+ years that is paid in full).
• Property taxes paid: Property taxes must have been paid on your home for the year.
• Income thresholds:
  
  • Single seniors: Full $500 grant if adjusted net income is below $35,000. Grant is reduced by 3.33% of income over $35,000. No grant if income reaches approximately $50,000 or more.
  • Married/common-law couples: Full $500 grant if combined adjusted family net income is below $45,000. Grant is reduced by 3.33% of income over $45,000. No grant if income reaches approximately $60,000 or more.

Grant amount:

The maximum grant is $500 per year (or the amount of eligible property tax paid, whichever is less). If your property tax for the year is $400, your grant is capped at $400.

How to apply:

1. File your annual income tax return for the previous tax year.
2. Complete Form ON-BEN (Ontario Benefits Application), which is included in the tax package for Ontario residents.
3. Check box 61070 and enter your eligible property tax amount beside box 61120.
4. Submit the completed form with your income tax return.

Payment is issued by the CRA, typically within 4–8 weeks after your Notice of Assessment. It arrives by direct deposit or cheque.

Example:

A single senior with an adjusted net income of $38,000 and $600 in property taxes paid:

• Income over threshold: $38,000 − $35,000 = $3,000
• Reduction: $3,000 × 3.33% = $100
• Grant amount: $500 − $100 = $400

Seniors and persons with a disability property tax exemption

If you've made home modifications to accommodate a senior or person with a disability, you may qualify for a property tax exemption on a portion of your home's assessed value. The exemption covers only the portion attributed to accessibility improvements, not the entire home.

What qualifies: Renovations or additions that make the home accessible, such as wheelchair ramps, widened doorways, accessible bathrooms (roll-in showers, grab bars), stairlifts or residential elevators, and modified kitchens or living spaces.

How to apply: Contact MPAC to request the exemption and provide documentation of the renovations, including receipts, contractor invoices, and a description of the accessibility features. If approved, the exemption will be reflected in your MPAC assessment and will reduce your taxable value going forward.

Use home equity to cover urgent property tax shortfalls

If you're facing a property tax bill you can't cover, or if unpaid taxes are starting to pile up, tapping your home equity can give you the lump sum needed to clear the debt and avoid penalties or tax sale proceedings. If you're also weighing other debt management strategies, it may be worth exploring whether a consumer proposal or a home equity line of credit (HELOC) is a better fit.

How Lotly's secured home loan can help:

Lotly's secured home loans let Ontario homeowners with existing equity borrow between $10,000 and $1,000,000 to cover urgent expenses like overdue property taxes, debt consolidation, or major home repairs. Unlike traditional bank loans, Lotly works with all credit scores and income types (including self-employed, benefits, and side-gig income), so you can still get approved even if you've been turned down elsewhere.

Real-world scenario:

Say you've fallen behind on property taxes due to a job loss or unexpected expenses. A Lotly secured home loan can provide the cash to pay off the arrears in full, usually within about two weeks. That stops interest charges (which can reach approximately 15% annually on municipal tax arrears) and prevents a tax lien from being registered against your property.

The process:

1. Check your home equity: property value minus mortgage balance.
2. Apply online or book a free consultation with a Lotly expert.
3. Provide basic documentation (proof of income, property details).
4. Receive approval and funding, usually within about two weeks.

If high-interest credit card debt or other loans are making it hard to keep up with property taxes, Lotly's debt consolidation solutions can roll multiple payments into one manageable monthly amount, so more of your income stays available for bills like property tax. You can also compare current HELOC rates in Canada to see how a secured line of credit might work for you.

Ready to take control of your property taxes?

Now that you've got the full picture, here's a quick recap of the moves worth making:

• Run the numbers yourself. Use your MPAC assessed value and municipal tax rate to estimate your annual bill. If you're buying, compare tax costs across cities before committing.
• Claim what you're owed. Seniors can get up to $500/year through the OSHPTG, and homeowners who've made accessibility modifications may qualify for assessment exemptions.
• Challenge errors early. If your MPAC assessment looks too high, file a Request for Reconsideration with comparable sales data, photos, and documentation of any errors.

If you're struggling to keep up with property tax payments, or if high-interest debt is eating into your budget, Lotly's secured home loans can help. Access your home equity to clear arrears, pay down debt, and get back on solid footing.
