Assessed value is an estimate of a property's market value as of a legislated valuation date, used as the base for calculating property tax. BC Assessment, for example, estimates each property's market value as of July 1 of the prior year, considering factors such as size, age, condition, view and location.

Assessment is carried out by a dedicated authority that varies by province. In Ontario it is the Municipal Property Assessment Corporation (MPAC); in British Columbia it is BC Assessment; in Alberta, municipalities such as Calgary assess properties directly. The authority provides values to municipalities, which then set tax rates.

Ontario's province-wide reassessment has been postponed. MPAC confirms that assessments for the 2026 property tax year continue to be based on fully phased-in January 1, 2016 values. MPAC still updates individual assessments for new construction, renovations, demolitions or a change in use.

It depends on the province. BC Assessment updates values annually (as of July 1). Alberta municipalities also assess annually. Ontario's regular four-year cycle is currently frozen at January 1, 2016 values pending the next province-wide update.

Not necessarily. In Ontario, a province-wide reassessment is revenue-neutral: it redistributes each property's share of the total tax a municipality needs to collect, rather than raising total revenue. If every property changed by the same percentage, individual shares would stay the same. What matters is how a property moves relative to the average.

Yes. MPAC provides the AboutMyProperty tool for Ontario owners to compare their property with others and review how the assessment was determined. BC Assessment offers a free Assessment Search service at bcassessment.ca to look up and compare values across the province.

A tax rate (sometimes called a mill rate) is the amount of tax charged per dollar of assessed value. It is often shown as a percentage. For example, a total residential rate of 0.75% means an estimated CAD 7.50 of tax per CAD 1,000 of assessed value. The rate is calculated from the municipal and provincial budgets divided by the total assessment base.

A residential bill is typically split between a municipal portion that funds local services and a provincial education portion. For Calgary in 2026, the City reports that about 42% of a residential bill is the provincial portion, collected by the City on behalf of the Province, with the remainder funding City services.

An announced municipal increase covers only the city's own portion. The provincial education portion can change separately, and an individual property can also shift if its assessed value moved differently from the average. In 2026, Calgary reported the provincial portion rose 19.8% for residential properties while the municipal portion rose about 1.8% for a typical home.

Programs vary by jurisdiction. British Columbia offers the Home Owner Grant, which reduces annual property tax on a principal residence below an assessed-value threshold (set at CAD 2,075,000 for 2026). Many municipalities also offer relief for eligible low-income seniors and people with disabilities. Eligibility and amounts are published on the official program pages.

Some provinces offer deferment programs for eligible owners, where the province pays the municipal tax and registers a charge that is repaid later, with interest. British Columbia administers a property tax deferment program, with interest rates updated in its 2026 Budget. Details and eligibility are set out on the official provincial page.

The process is run by the assessment authority. In Ontario, owners file a Request for Reconsideration with MPAC — the deadline for the 2026 tax year is March 31, 2026. In British Columbia, owners may file a Notice of Complaint (Appeal) for an independent review by a Property Assessment Review Panel, with a deadline of February 2 for the 2026 roll.

The federal Underused Housing Tax (UHT) has been eliminated for the 2025 calendar year and beyond. Following Bill C-15, affected owners are not required to file a return or pay the tax for 2025 and subsequent years. Filing and payment obligations for 2022, 2023 and 2024 still apply. The UHT was always separate from annual municipal property tax.

Several provinces and cities have their own vacancy taxes — for example a municipal vacant home tax or a provincial speculation and vacancy tax. The CRA notes these are separate from the federal Underused Housing Tax and have their own rules; being exempt from one does not affect the others. Each is administered by its own city or province.

New construction is added through a supplementary or omitted assessment once the property is complete and occupied, rather than immediately. MPAC issues a Property Assessment Notice when a change such as new construction, an addition or a change in use occurs. In Ontario, any added value must reflect what the improvement would have been worth at the January 1, 2016 valuation date.

Programs tied to assessed value can shift when values change. For 2026, BC lowered the Home Owner Grant threshold to CAD 2,075,000 (from CAD 2,175,000) to keep the same share of homes below the cutoff as values softened. A lower assessment may bring some homes back below a threshold, while the grant phases out above it at CAD 5 per CAD 1,000 of value above the threshold.
