The party never fully recovered from the fragmentation of Mulroney's broad coalition in the late 1980s, resulting in part from the failure of two provinces to ratify the Meech Lake Accord. The party suffered a decade-long decline following the 1993 federal election, during which it did not hold more than 20 seats in the House of Commons. It formally dissolved on December 7, 2003, when it merged with the Canadian Alliance to form the modern-day Conservative Party of Canada.
