Here is the piece most coverage skips, and it is the key to understanding why your bill can rise even when your city behaves itself. Your municipality sets one part of your property tax. Your province sets another part, collects it through the very same bill, and gets very little of the blame when it goes up.
The clearest example in 2026 is Alberta. The education property tax — the portion of your bill that funds the K–12 school system rather than your city's services — is set by the province and simply collected by your municipality. For 2026–27, the Government of Alberta raised that education requisition from $3.1 billion to $3.6 billion, a jump of about 19.8%, with residential and farmland education rates set at $2.84 per $1,000 of equalized assessment. That single provincial decision is why Calgary's all-in increase reached 8.1% even though the city's own portion barely moved. We will come back to Calgary below, but the lesson is national: when your bill jumps, your city council may not be the one who moved it.
Provinces shape your bill in quieter ways too. In New Brunswick, the province legislated a one-year freeze on the assessed values used for 2026 tax bills, holding most taxable assessments at their 2025 level while it works on a longer tax-system reform. The Government of New Brunswick framed it as temporary relief, and it is the reason a city like Saint John could actually lower its rate this year. In Quebec, the opposite pressure is at work: cities periodically file a new assessment roll — a fresh valuation of every property — and Montreal's latest roll lifted average values by about 12.2%, which pushes bills upward regardless of what the tax rate does.
In British Columbia, the province levies a school tax inside your bill and runs a property tax deferral program whose interest terms are changing in 2026, something the Province of British Columbia flagged in its tax-change summaries. Ontario, by contrast, has held its provincially set education rate flat for years, which is one reason Ontario's 2026 increases are driven almost entirely by municipal budgets.
