The September 4th edition of the Toronto Star mentioned that "teachers’ compensation has increased by 25 per cent during the McGuinty government."
To the general public, this would seem like a pretty cut and dry argument and it goes like this:
One reason why Ontario has a deficit is because they are spending more on education and this is mainly due to an increase in teacher salaries.
But according to Stats Canada, this simply isn't true.
Take a look at the chart below, focussing carefully on Ontario
According to this chart, the percentage of the education budget that is going to educators, which Stats Can considers to be teachers and administrators, has gone up by only .7 of a percent since 2005 (It started at 46.6 and ended at 47.3).
Also note that it is on a downward trend (48.6 - 47.3)
Thus, while the education budget has increased by nearly 3 billion dollars in the same period (Ontario Ministry of Education) only .7 percent of this increase is due to teacher salaries.
