I don't understand why Canada allows circumvention of the rules for illegal border crossers. This would be easy loophole to plug?I actually think a large number are arriving through the US because they were denied a Canadian TRV but we're able to get a US travel visa or already had one. They are not spending much time in the US. They seem to have quite a high approval rate. Goodale has already spoken with the US since some US embassies seem to be giving out US travel visas suspiciously easy. In general it is much harder to get a Canadian travel visa than one for the US.
Arriving this way seems un-Canadian
