This is a non-issue, it will disappear.  And come next election time Trudeau will point the media and Canadians in a winnable direction (it might be about a tax cut for his "middle class" or a pipeline through a forest or some new refugees or oh, look, a squirrel) and we'll all dutifully follow his direction and ignore all the other issues of the previous 3 or 4 years of his reign.  And he'll sweep back to power as effortlessly as he did last time.  Canadians remain mesmerized by the name "Trudeau", end of story.
