In Ontario, Canada's case, some goods are not taxed with both the GST and PST. However, an HST cannot make such a separation and those goods will be taxed at the standard HST rate. This leads to higher revenues for the government. This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
