The 1902 Ontario general election was the tenth general election held in the province of Ontario, Canada. It was held on May 29, 1902, to elect the 98 Members of the 10th Legislative Assembly of Ontario ("MLAs").
The Ontario Liberal Party, led by Sir George William Ross, formed the government for a ninth consecutive term, although with only a very slim, two-seat majority in the legislature.
The Ontario Conservative Party, led by Sir James P. Whitney formed the official opposition.
The number of electoral districts was increased from 93 to 97, under an Act passed in 1902. Ottawa in both cases was entitled to elect two members, and thus 98 MLAs would now be elected to the legislature. The following electoral changes were made:
Ottawa had two seats, and plurality block voting was used. Elsewhere the first-past-the-post election system was used.
Margaret Haile, a Canadian Socialist League candidate in Toronto North, made history as the first woman ever to run for political office in Canada.
