The
goods and services tax (GST) is a multi-level
value added tax introduced in
Canada on January 1, 1991, by then-
Prime Minister Brian Mulroney and his finance minister
Michael Wilson. The GST replaced a hidden 13.5% manufacturers' sales tax (MST); Mulroney claimed the GST was implemented because the MST was hindering the manufacturing sector's ability to export competitively. The introduction of the GST was very controversial. The GST rate is 5%, effective January 1, 2008.
