I live in Calgary. I won't sully this fine gathering by typing out what we call the poor b**t**ds that live in Edmonton, but I will give you some insight into the colourful names we have here for people from different regions.
My father is from New Brunswick (herring choker). He moved to Ontario in search of work (sellout). That happens a lot. He left behind the 'bluenosers' of Nova Scotia, and the 'spud islanders' of Prince Edward Island. He passed through Quebec ('pea-soupers') on his way to Ontario (tetes carres).
He married an Ontario woman. She would be called an 'Upper Canadian' by the folk he left behind in 'The Maritmes', or a 'mainlander' by the 'noofies' of Newfoundland.
The capital of Ontario is Toronto (Hogtown), the populace of which considers their city to be the centre of the known universe, largely based on near-total ignorance of the rest of the world. Canadians, (being basically smug sorts), are united in their disdain of Hogtown.
I lived for the last 25 years in Ottawa, which is the capital of Canada. This means that the citizens of Ottawa (f'n' bureaucrats) are almost as universaly reviled as people in Hogtown!
I moved to Calgary, (Cowtown), a couple of years ago, because I was suffocating in the atmosphere of entrenched socialism (%$%*&$# Liberal Party of Canada!) in Ontario (down East). In doing so, I crossed the provinces of Manitoba and Saskatchewan (flatlanders).
Here, (in God's Country), we poke fun at Edmonton (a festering boil on the buttocks of the North), because its the capital of Alberta (Oil Patch country).
Across the Rocky mountains, is the province of British Columbia, (British California), which extends all the way to the Wet Coast. (Yes, that [u]is[/u] spelled correctly).
The only thing that we enjoy more than inventing colourful names to call each other is beating up on fools who poke their noses into our family spats (constitutional reform conferences).
I do hope this has helped to clarify things. :D
