Yes. On the broad question of why this is happening throughout the west—this rise of fairly xenophobic, obviously racist politicians and political parties—on that front, there's a lot going on and I wouldn't pretend to be able to explain it all. But I would say that certainly economic dislocation combines with pre-existing xenophobia to produce this kind of potent mix.
I guess the one thing I would say, in terms of what the government can do to push back against that and to prevent it from spreading north, is that by far the most important thing is that the messages people get aren't mixed, that the message people get from politicians, both on the government side and on the opposition side, is unified—that this is a good thing, that immigrants have a positive impact on Canada.
Once you have a mixed message coming from political elites, people are much better able to pick and choose the message that fits with their viewpoint. Then you do see polarization.
