n. — Administration, Finance
a value-added tax levied by various provinces.
Type: 1. Origin — Provincial sales tax is levied by a number of Canadian provinces. Some, like Alberta and the Territories, do not levy a PST. Others, like Nova Scotia and New Brunswick, have combined the PST with the federal GST (Goods and Services Tax) to create a Harmonized Sales Tax or HST. Although provincial sales taxes were levied as early as the 1930s in Alberta - which later dropped the tax - it appears the abbreviation PST was not used until the 1970s. PST originated and remains most prevalent in Canada (see Chart 1).
