if you quit hiring them, they'd quit coming. i haven't the slightest bit of sympathy for your illegal immigrants issue, we have troubles of our own. Canada has the exact same problems the usa has with immigrants, and for the exact same reason: the greed of the business community.

we don't have a southern border with mexico, they come in on jet planes. most canadian immigrants aren't even illegal, they have landed immigrant status when they get here. and they come from all over the world. that's why your proposed wall-building activities are nothing but racism, pure and simple. the best way to keep little brown people from coming into your country uninvited is to fine the big fat white people who invite them. Of course, you'd probably call that a tax.
