Here's a wiki on it. http://en.wikipedia.org/wiki/List_of_Canadian_provinces_and_territories_by_gross_domestic_product
Though I would argue that is out of date, since there was a lot of economic activity in 2007 and 2008. Namely, Ontario's large loss of manufacturing jobs and continued growth in Alberta and Saskatchewan. Either way, GDP per capita isn't a very good indicator, as cost of living varies greatly from province to province. ie. in Calgary, you will have sky-high housing prices (I would say for an average home, in an average middle class area you are looking at 500k+) but you have no PST (provincial sales tax) and more likely, a higher wage (even working typical "minimum wage" jobs such as fast food). In Regina, you could buy that same home (until this past year) for about 150k, but you would have PST and a higher income tax. But you would also have cheaper auto insurance and health care which covered more things. But you wouldn't be living in a big city.
Either way, I prefer western Canada and it's going our economy is going to continue to grow, regardless of oil and mining.
