I believe Mr Trudeau and his advisors are more adept than anyone else at reading the voters (all the voters), and every decision he announces is made in that context.  He has sailed through every negative issue that has come out about him, his continual high popularity ratings (unusual for a politician solidly into his term of office) throughout everything so far seems to bear that out.  I see no single issue that would cause Canadians to end their love affair with him.  I'm not very happy about it, but he seems bulletproof to me.
