Toronto has some of the lowest property taxes in the province. That is all well and good if you're flush with cash, but... Why does the obvious keep getting overlooked?
but they also use property values from 8 years ago.
That's true across the province. That has no impact on the total amount collected, though.
It really only means that properties that have been improved over those years might be paying less than their fair share (with others paying more than their fair share). That might be of concern to individuals, but makes no difference to the city.
