We already know there is a constitutional reason why gst/hst can't be included in the price in Canada.

Much of the reason for the notoriety of the GST in Canada is for reasons of an obscure Constitutional provision. Other countries with a Value Added Tax legislate that posted prices include the tax; thus, consumers are vaguely aware of it but "what they see is what they pay". Canada cannot do this because jurisdiction over most advertising and price-posting is in the domain of the provinces under the Constitution Act, 1867[7]. The provinces have chosen not to require prices to include the GST, similar to their provincial sales taxes. As a result, virtually all prices (except for gas pump prices, taxi meters and a few other things) are shown "pre-GST", at the merchant's choice.
