At least there would  be 2 distinct choices in the next election. Not sure Canada is ready for someone with his views but you never know and anything can happen in an election. . 

The base of Conservatives  around 30 % may like him but you cannot win with 30% . 
Because of his views which tend to be quite right of Centre , I suspect many NDPers would vote for Liberals to make sure he does not get into power as they would not want to split the vote. (this happened last election)
Also the immigrant vote is around 20%.  Not sure he would do well with this group .  
Right now the Conservatives are 12 % (42-30) behind the Liberals according to the latest Nanos poll but that can change quickly with the right candidate .  

It sure would be an interesting election.
