“Our immigration policy should not aim to change the cultural character and social fabric of Canada, as radical proponents of multiculturalism want.”

There is nothing in that sentence that is either racist or intolerant.  

I think Mr. Ibbetson and a lot of smug "progressives," will be surprised at the next election to learn there is a very large percentage of the population of Canada who agree with this statement.  Too many "progressives," have for too long been listening only to their own echo-chamber.
