Some Canadianisms:
Nova Scotia - Bluenosers
Halifax - Haligonians
British Columbia - British Columbians
Newfoundland - Newfoundlanders, Newfies, Newfs
Prince Edward Island - Islanders
Saskatchewan - Saskatchewanians
Toronto - Torontonians
Manitoulin Island - Haweaters
Smithers - Smithereens (my favourite!)
Quebec - this one has been controversial in English. Properly, it's Quebecois(e)(s), prounced in the French way. I think something that sounds like Kay-bec-wah is currently acceptable. Verboten are Kwee-beckers and Frogs.
Madawaska area of New Brunswick - Brayon
non-native of Maritime provinces of Canada = come-from-away
descendant of original French settlers in Quebec = pure laine
