Side by side

Assessed value, not market price. Ontario assessments still reference 2016 valuations, and the two places may sit at different distances from current market value — which is why a rate gap is not the same as a bill gap for comparable houses.

Where the difference comes from

Both are towns inside a county or region, both in York Region, so they pay the same county rate of 0.38% and the entire difference comes from their own councils.
