Remarks

1. ↑ Macdonald led a coalition of the Liberal Conservative Party and the Liberal Party.
2. ↑ Blake resigned to lead the Liberal Party of Canada at the federal level after “dual mandates” (activities at different levels of government) were banned.
3. ↑ Drury won his seat in the legislature only in 1920 in a by-election.
4. ↑ Drury led a coalition of the United Farmers of Ontario and the Labor Party.
5. ↑ Drew's party won the election, but he himself lost his seat in High Park and later resigned instead of seeking a by-election.
6. ↑ Miller's Progressive Conservatives had more seats than Peterson's Liberal Party, but Peterson had the formal commitment of the New Democratic Party in the form of a written agreement. Both parties defeated Miller with a vote of no confidence and formed a government under Peterson without an official coalition.
