That's the comparison you want to make? Detroit?  Take a minute, if you like.

The original complaint was that teacher's salaries are out of line with the rest of society.  (I assumed that it meant "Ontario."  But I think if you want to cast your net a little wider, they are probably paid much more than teachers in, say, The Gabon, also.). As you suggest, I think they are roughly tantamount to the pay of police officers and firefighters.
