"Canada can only deport to country of origin, the US."

These refugees aren't American.  We can't FORCE the US to accept non-Americans.  I don't know where you got the idea that was possible.  The US is well within their rights to refuse to take these refugee claimants back.
The ONLY place we could reasonably deport them to is their country of origin, which is NOT the US.  They are refugee claimants in the US, but it is NOT their origin.  Attempting to insult me won't alter the reality that Canada cannot send these people back to the US if the US refuses to take them.

Do you even know WHY they are coming across illegally?  Have you looked up the relevant law?  It's amazing how many people are horribly informed about what's happening.  I'll count you among them.
