First of all, migrant "invasions" are bullshit and this is a pure moral panic cooked up by fascists which for whatever reason (read: white supremacy) the liberal establishment has conceded to over the better part of my lifetime to try and court the people they actually WANT to vote for them (suburbanite crackers) rather than their actual base.
But also, a migrant invasion from Canada? What's that a couple pro hockey teams and a handful of hollywood actors?
Absolute rubbish.
