You sure about that? As recently as 1995, Canada was with 0.4% of a vote to split the country in two.
In the 1970's the deputy Premier of Quebec was kidnaped and murdered by Quebec separatists.
In 1990 the Canadian and Quebec governments used the military and authorized lethal force to put down an armed rebellion by the Mohawk tribe, after a Canadian court allowed the development of a golf course on native land.
Just because Canada is largely ignored by the American and International media, doesn't mean that everything is lovely and everyone is sitting around singing kum ba yah.
