The Canadian authorities are competent and able to find sleeper cells. The Mexican authorities (especially local police) are as corrupt as the days down there are long, and couldn't find a sleeper cell if they tried. They can't stop gangs from killing newspaper reporters and other people who shed light on their shenanigans in Nuevo Laredo or other border cities. What makes you think they would be able to stop Al Qaeda from entering their country or crossing the border? Heck, the corrupt federales would probably help them cross.

I don't think they could. The Canadians couldn't (it was US agents who caught the bomb guy).

There just seems to be a much more Jihad sympathetic population in Canada.
