50 Cent was banned from Canada in 2005
Canada's Junior Foreign Minister Dan McTeague said this about 50 Cent: "There are indeed limits and restrictions on freedom of expression. Particularly if they incite hate or if they are the kind of activity that is killing our youths right now across Toronto."
Apparently, Canada was worried that 50's presence would incite violence, and they banned him from entering the country to perform. We know Canada doesn't usually accept American currency, but couldn't they make an exception for 50 Cent?
