As an immigrant I submit that sometimes people are so desperate they are just going to apply for any place they can get, anything better than their own country. This is evident in our migrant vessels where people get on a ship and they may end up anywhere.
The way I look at it is if you provide them with some knowledge before coming here, at least that's a start. Because we do have testing before they get their citizenship status, before we make them Canadian citizens. Maybe some knowledge before they come here might be useful to provide them at least with what Canada is all about.
