I think that for many, many of President Elect Trump's supporters, perception is far more important than is reality.
My guess is that
some illegal drugs and
some illegal immigrants are crossing into
from
; far fewer, I suspect than are coming across the USA/Mexico border but enough to make it true and, therefore, enough to force Canada - no matter which party is in power - to take some action to address Mr Trumps' concerns.
Those are actions we should have been taking anyway by exercising proper controls of all border crossings.
