List of premiers of Quebec by time in office

Under this system, Maurice Duplessis was Quebec's longest-serving premier, holding office for a total of 18 years and 82 days over two non-consecutive terms.

[1][2] The premier's term begins upon appointment by the lieutenant governor of Quebec, usually after winning a general election.

Four premiers have died in office (Felix-Gabriel Marchand, Duplessis, Paul Sauvé and Daniel Johnson Sr.) All others have resigned, either after losing an election, a parliamentary no confidence vote, or upon retirement.

The transition period and the date for the transfer of office are negotiated by the incoming and the outgoing premiers.

Pierre Marc Johnson served the shortest term in Quebec history, only 70 days, in this way.

He was selected by the Parti Québécois to replace René Lévesque, just before the general election of 1985, which Johnson and the PQ lost.

Antonio Barrette, Daniel Johnson Jr., Edmund James Flynn, Jean-Jacques Bertrand and Bernard Landry each served short terms for similar reasons.

Joly resigned following a vote of no confidence while Marois left office after her party's defeat in the following election.
