Speaker of the Ontario Legislative Assembly

The Speaker of the Legislative Assembly of Ontario is the presiding officer of the provincial legislature. Since 1990 the position has been elected by MPPs using a secret ballot. Previously, the Speaker had been appointed by the Premier of Ontario after consultation with the Leader of the Opposition and the leader of the third party and then ratified by the legislature. David Warner was the first Speaker to be elected by his or her peers.

The Speaker is usually a member of the governing party. The only exceptions have been Jack Stokes, Nelson Parliament and Hugh Edighoffer. Stokes was the NDP MPP for Lake Nipigon, and was named Speaker by Progressive Conservative Premier Bill Davis. Davis was elected to lead a minority government and having an opposition MPP as Speaker was a means of denying the opposition one vote (as the Speaker only votes in the occasion of a tie and then must vote by precedent). Nelson Parliament was a Liberal who became Speaker when the United Farmers of Ontario formed government as the entire UFO/Labour caucus were freshly elected with no legislative experience. As a result, the Premier, E.C. Drury, looked to the opposition benches for a Speaker. Upon becoming Speaker, Parliament resigned from the Liberal caucus and sat without party affiliation. While this is the normal practice in the British House of Commons, it is the only time it has happened in Ontario.
