43rd Ontario general election
The 43rd Ontario general election will be held on or before June 2, 2022. As of December 2016, Ontario elections are held on the first Thursday in June in the fourth calendar year following the previous general election unless the Legislative Assembly of Ontario is dissolved earlier by the Lieutenant Governor of Ontario due to a motion of no confidence. Such a dissolution is unlikely as the current government has a majority.
124 seats of the Legislative Assembly of Ontario
63 seats needed for a majority
|Progressive Conservative||Doug Ford||76||73|
|New Democratic||Andrea Horwath||40||40|
|Liberal||John Fraser (interim)||7||7|
Note that for purposes of the administration of the Assembly, parties with fewer than 8 seats are not recognized, and their members are treated as independent MPPs.
- June 7: The Progressive Conservative Party of Ontario under Doug Ford wins a majority government in the 42nd Ontario general election, with Andrea Horwath's New Democrats forming the Official Opposition.
