What is PST? | PST Full Form | PST Term

The goods and services tax (GST; French: Taxe sur les produits et services) is a value added tax introduced in Canada on January 1, 1991, by the government of Prime Minister Brian Mulroney. The GST, which is administered by Canada Revenue Agency (CRA), replaced a previous hidden 13.5% manufacturers’ sales tax (MST).
Introduced at an original rate of 7%, the GST rate has been lowered twice and currently sits at rate of 5%, since January 1, 2008. The GST raised 11.7% of total federal government revenue in 2017–2018.
In five provinces, Nova Scotia, New Brunswick, Newfoundland and Labrador, Ontario and Prince Edward Island, the GST is combined with provincial sales tax (PST) into a harmonized sales tax (HST). In Quebec both GST and QST are collected and administered together by the provincial government. British Columbia had an HST from 2010 until 2013, when it was removed after a provincial referendum. Alberta and the territories of Yukon, Northwest Territories and Nunavut have the GST but no provincial or territorial sales taxes.
