Your assessment is frozen at 2016 values

Ontario taxes on January 1, 2016 values, and a sale does not reset them. On a building bought at $1,000,000 whose assessment sits near $550,000, the tax is computed on that assessment, not on the price.

That is an advantage today and a liability tomorrow: when the roll is updated, expect about $6,249 more per year in Ajax, or $521 a month. Plexmeter derives it from your own tax bill, with no market averages.
