Here's an article (admittedly from 2012) on teachers salaries in Ontario: http://www.theglobeandmail.com/news/national/education/anato...
More recent reports (from the shrill National Post) claim an average salary of almost 87K for secondary school teachers, but they don't state their source information.
Also consider that teachers - like other public sector unions - are one of the last few sectors to get a defined benefit pension plan, a luxury that few others will ever have.
