Here's what I'm seeing from my calculations:
Mill rate changes*:
City +4.8%
Province +11.3%
(combined 7.288%)
If you multiply your home's %-change in assessed value by the mill rate change you should see the total %-impact in your taxes (alternatively, if you take your change in taxes and divide by the mill rate %-change you'll find the change in your assessed value).
Therefore... if your taxes increased by more than 7.3% than your home's assessed value also increased.
* as these are mill rates, it doesn't necessarily mean that the city (province) only raised taxes by 4.8% (11.3%). eg. if the city also increased average assessments by 10% their effective increase would be ~5.3% (conversely if avg. assessments decreased by 10% the effective tax change would be 4.3%)
[Edit: I see here:
http://globalnews.ca/news/2433990/20...-need-to-know/ that the average property assessment dropped 1% this year, so the average homeowner should expect to see a property tax increase of 7.22% (city +4.75%; prov. +11.2%)]
