Taly, I pulled the data from wiki, and they say:
Quote:
Provincial and federal sales tax rates at the retail level on goods and some services are as follows:
Province HST GST PST Total Tax
Alberta 5% 5%
British Columbia 5% 7% 12%
Manitoba 5% 7% 12%
New Brunswick 13% 13%
Newfoundland and Labrador 13% 13%
Nova Scotia 13% 13%
Ontario 5% 8% 13%
Prince Edward Island 5% 10% 15.5%*
Quebec 5% 7.5% 12.875%*
Saskatchewan 5% 5% 10%
* in Québec and PEI, PST is calculated on the total price including GST
So the 15% was an additive estimate of taxation. I don't think the numbers are all accurate to more than a few percent... but they serve to show the disparity between taxation in European countries, Canada, and the US.
