"A resident of Hamilton, Ontario, Canada, Aziga was a former staffer at the Ontario Ministry of the Attorney General." The guy was working and contributing to the country. The article doesn't say anything about why he was granted residency or whether he was a refugee.

Looking online now he was a refugee but i figure i guy that this guy would have gotten through as a normal immigrant. I don't know much about the Canadian policy to be honest. I am more familiar with the US system and it is a complete mess.
