Property Tax Calculator

What the Property Tax Calculator does

This calculator turns an assessed value (or an estimated one, from a purchase price) into your annual and monthly property tax bill for a specific Canadian municipality, using that city's current total residential mill rate. It is the same figure your mortgage lender uses in your qualifying ratios, and the same figure that feeds the affordability, closing costs and total carrying cost calculators elsewhere on this site.

Because property tax rates vary enormously between neighbouring municipalities — sometimes by a factor of two or more for otherwise similar homes — this calculator also shows what the same assessed value would cost across every city in our table, so you can see exactly how much of your bill is the city you chose.

• Annual and monthly property tax for your city
• The total mill rate applied, combining municipal, education and special-levy components
• A city-by-city comparison at the same assessed value
• A multi-year projection at an assumed annual increase
• A clear flag when assessed value is estimated from purchase price rather than entered directly

The key variables that move the answer — and how each municipality treats them

Two things decide your bill, and they are set by completely different processes.

• Assessed value — the tax base, set by a provincial assessment authority (MPAC in Ontario, BC Assessment in British Columbia, and equivalent bodies elsewhere), not by the municipality and not by your purchase price. In most provinces outside Ontario, assessed value tracks close to current market value. In Ontario, assessments are based on a valuation year that has been frozen for an extended period, so assessed values frequently sit well below what a home would sell for today.
• The mill rate — set annually by each municipality as part of its budget process, almost always in the first quarter of the year, and it varies enormously by city. Rate differences between neighbouring municipalities in the same region are common and can mean a materially different tax bill on two otherwise identical homes just a short drive apart.
• Property class — residential, multi-residential and commercial properties are taxed at different rates within the same municipality, with non-residential classes typically taxed at a meaningfully higher rate. This calculator applies residential rates only.

How property tax is actually calculated in Canada

The core formula is simple: annual property tax equals assessed value multiplied by the total mill rate, where the mill rate itself is a blend of the municipal operating levy, the provincial education levy, and, in some cities, additional special levies for transit, infrastructure or other city-building priorities. This calculator uses each municipality's combined, total residential rate rather than breaking out the individual components, because those sub-components shift every year with each city's specific budget lines and a stale breakdown would be more misleading than a current total.

When only a purchase price is available, an estimated assessed value is calculated by applying a documented assessment ratio for that city — this is explicitly flagged as an estimate, because purchase price and assessed value are answers to two different questions and treating them as interchangeable is the single most common property tax mistake homebuyers make, particularly in Ontario.

The multi-year projection simply compounds the current annual figure forward at an assumed rate you choose — it is a budgeting tool, not a prediction from any assessment authority, and actual increases depend on decisions your municipal council has not yet made.

• Annual tax = assessed value × total mill rate
• Total mill rate = municipal + education + any special levies, combined per city
• Monthly = annual ÷ 12, the figure lenders use in debt service ratios
• Estimate from price = purchase price × documented assessment ratio, flagged as an estimate

What you get from this calculator, and how lenders use the number

Property tax is counted in full — 100% of the annual amount, divided by twelve — in your Gross Debt Service and Total Debt Service ratios, alongside your mortgage payment, heating and any applicable condo fee. Unlike a condo fee, which is only partially counted, property tax gets no discount in a lender's math, so an inaccurate estimate here can meaningfully distort an affordability calculation done elsewhere.

• Annual and monthly property tax — feeds directly into GDS and TDS alongside your mortgage payment
• Mill rate — lets you sanity-check a stated tax bill against the current published rate for that city
• City comparison — useful when weighing a purchase across two or more municipalities in the same search radius
• Multi-year projection — a planning input for a longer-term ownership budget, not a guarantee

Using your results well

If you are comparing homes across municipal boundaries, run this calculator for each city at a comparable assessed value — the mill rate difference alone can be worth thousands of dollars a year and belongs in the comparison alongside price and condo fees. If you already have a specific listing, ask the listing agent or your municipality's assessment portal for the actual current assessed value rather than relying on the purchase-price estimate here.

What this calculator does not do is model special assessments tied to a specific property, phased-in assessment increases following a reassessment, or non-residential tax classes. It also does not account for property tax rebate or deferral programs some municipalities offer to seniors or low-income owners — those are worth investigating separately if they might apply to you.

• Get your actual assessed value from your municipality's assessment authority when possible
• Compare across neighbouring cities before assuming property tax is a rounding error in your decision
• Remember lenders count property tax at 100% in your qualifying ratios, unlike condo fees
• Use the projection as a budgeting cushion, not a guaranteed number — councils set rates annually
