The United Farmers of Ontario entered politics by contesting a 1918 by-election which was won by UFO candidate Beniah Bowman. The next year, in the 1919 provincial election in Ontario they achieved a major political upset by winning enough seats to form a government in alliance with Labour MLAs in the Ontario legislature (also listed). The UFO did not have a leader until after the 1919 election when Ernest Charles Drury was asked by the caucus to serve as Premier of Ontario. As he did not have a seat in the legislature he had to enter via a by-election.
Three candidates were elected under the Patrons of Industry banner in the 1894 general election:
Twelve Liberals and one Conservative were also elected on a joint ticket with the Patrons. The party did not elect any candidates in the 1898 election.
