Oh yes, I understand that, almost everywhere has illegal immigrants. However, for one reason or another, the impact of the illegal immigrants in Canada (which according to figures number 1/6th of the amount in the UK) is greatly lessened.
Of course it is, because Canada is absolutely enormous. They have a population of around half ours, too, so on a per capita basis using your figures we have 'only' 3 times more illegal immigrants which given how appealing we are to African migrants who haven't a hope in hells chance of crossing the Atlantic that's not actually that bad on our part, surely?
