In the spirit of this thread, I sat down and calculated the actual income tax rates (on taxable income) for all Canadian citizens living in all provinces, excluding Quebec. For anybody who is interested, I can give a maple spreadsheet that has all the details or I can calculate individual tax rates given a taxable income and a province of Canada.
Total tax rate for a person living in Ontario having $100,000 of taxable income (using 2007 rates:

Total Tax Rate = .29242404
I include that many decimal places so that you can count your pennies. For people who like percentages, that's 29.242404%
Now, my father lives in Alberta, and I think he makes about $70,000 a year if he gets a lot of overtime. That means his tax rate is 28.547757%, interestingly enough, because Alberta has a flat tax rate on all income at 10% your low income earnings are taxed at a higher rate than in other provinces, this means that, living in Alberta and making $100,000 a year, your tax rate will be 30.60915% exactly. From which we see, only the richest Albertans get taxed less than their equal earning counterparts in Ontario.
I am not a big fan of income to begin with, but I can show that if you take the high income tax rate formula (the tax rate as a function of income for the highest earners) and applied it to everybody (excepting the low income earners), that people who earn between $40,000 and $120,000 a year are currently being overtaxed by as much as 3.5%. And that if we treated the low income earners as we treated the high income earners, we would actually be giving them money, which is why I said "excepting the low income earners".
Just food for thought.
