I live in Alberta, so I only pay GST :) My point was, there are only 10 sets of tax rules a seller has to know to do business in Canada: 1. GST 2. BC PST 3.

Having to know, abide by, and follow the updates to 6000+ different sets of rules would be difficult even for large enterprises, let alone small businesses. I am glad Canada does not give the power to levy sales taxes to sub-province entities.
