Why your 2026 property tax bill is still based on what your home was worth in 2016

It's one of the strangest facts in Ontario housing, and every year it surprises another wave of homeowners: the assessed value on your property tax bill is your home's estimated market value on January 1, 2016. Not last year. Not pre-pandemic. A full decade ago — before three market cycles, a pandemic boom, and a condo correction.

How we got a ten-year freeze

MPAC — the Municipal Property Assessment Corporation — is supposed to revalue every Ontario property on a four-year cycle. The update planned for 2020 was postponed when the pandemic hit, then postponed again, then extended by regulation through subsequent assessment cycles. The province has mused about a new cycle with fresher values, but as of the 2026 tax year, bills are still calculated on fully phased-in 2016 values — and no reassessment date has been fixed.

One nuance: the freeze isn't total. MPAC still updates assessments when something physical changes — a new build, a major renovation, a demolition, a change of use. Buy a new-construction home and you'll get a notice with a value expressed in 2016 dollars for a house that didn't exist in 2016. It's exactly as odd as it sounds.

Who wins and who loses

Here's the part most people miss: a reassessment would not raise the city's total tax take. Toronto sets its levy first, then divides it across properties in proportion to assessed value. Reassessment just re-slices the pie. That means:

• If your home's value grew faster than the city average since 2016 — many detached houses in gentrifying east-end neighbourhoods — the freeze has been quietly subsidizing you, and a reassessment would raise your share.
• If your property lagged the average — many downtown condos, after a decade of flat prices — you're overpaying today relative to a fresh valuation, and reassessment would cut your relative share.
• The longer the freeze runs, the bigger those hidden gaps grow, and the more painful the eventual correction — which is exactly why no government has been eager to be the one holding it when it lands.

Your tax bill is a 2016 snapshot multiplied by a 2026 rate. Whether that bargain favours you depends entirely on what your street did in the last decade.

What you can actually check today

You can't make MPAC reassess the city, but you can see your own numbers. Pull the property tax and assessment details for your address — or one you're about to buy — and see the assessed value doing the work behind the bill. It feeds straight into carrying costs, so run it alongside the rest of the property snapshot before an offer, and see our full property tax explainer for how the rate side works. If you think even the 2016 value is wrong, MPAC takes reconsideration requests — but that's a correction, not an escape from the freeze.
