Perhaps Mr Mason should explore the rampant and out of control racism in Toronto and Vancouver, with both of those cities having much larger non-white populations, percentage wise and in raw numbers,  while having white mayors.

Nenshi played the race card and he knows it, and now he has to continue to play the hand out. By playing the race card, he cowed the media into refusing to look into his record on taxes and spending, and neatly dodged issues such as questions regarding how a $1/2 Billion airport runway underpass to nowhere could be approved, after first calling it ridiculous (which by the way, it is). 

A brilliant diversionary tactic, one that I have no doubt will soon be tried out on a larger political stage.

Well played Mr. Nenshi, well played.
