|Brian Mulroney of the Conservative party became prime minister of Canada
on September 17, 1984, and remained in office until his resignation in 1993 (after his support of NAFTA drew criticism within his party).
One of Mulroney's chief accomplishments of the 1980s was the Meech Lake Accord of 1987. Quebec had been the only province that did not ratify
Canada's new constitution in 1982. The Meech Lake Accord was to have made
changes to the 1982 Constitutional Act that would have made it acceptable to Quebec. However, the accord failed in 1990.
