This page lists results of Canadian federal elections in Southwestern Ontario.

Regional profile

Beginning at the start of the 1960s, Southwestern Ontario has traditionally given more support to the Liberals, aside from 1984, although there has always been a pronounced urban-rural split: the New Democrats (NDP) and Liberals are both stronger in Windsor and London, while the rural areas and Sarnia have leaned more towards the Conservatives due to their social conservative bent. The Liberals swept all the ridings in the region in 1993, 1997 and 2000, save one NDP win in 2000.

However, in the 2004, 2006, 2008 and 2011 elections, the entire region, incrementally swung away from the Liberals to support the Conservatives, including in London, where three-way vote-splitting resulted in two ridings switching from Liberal to Conservative. The loss of the second one, London North Centre, in the 2011 election, left the Liberals without any seats in Southwestern Ontario for the first time since Confederation. The exception to Conservative swing was in one London riding, London-Fanshawe, and in Windsor's two ridings, which remained with the NDP from 2006 right through the 2015 election.

In 2015, Southwestern Ontario's election results did not at all mirror the overall federal election results. The Liberals managed to take back two seats in the entire Region, both in London, but the NDP added a seat adjacent to Windsor, Essex, and the Conservatives retained four seats, three rural and also Sarnia-Lambton. The 2019 election saw the NDP lose two of the three Windsor area seats it held before the election, with one of each going to the Conservatives and the Liberals. This election also saw increased regional polarization, with all seats in urban London and Windsor being won by the Liberals or the NDP, and all other seats being won by the Conservatives.
