Elgin—Middlesex—London (provincial electoral district)

Elgin—Middlesex—London is a provincial electoral district in Ontario, Canada, that has been represented in the Legislative Assembly of Ontario since the 2018 provincial election. It was created from the electoral districts of Elgin—Middlesex—London (prior configuration) and portions of Lambton—Kent—Middlesex following the 2018 redistribution.

The riding primarily encompasses the southwestern portion of Middlesex County, the eastern portion of Elgin County, and a small section of the city of London. Major communities within the riding include the city of St. Thomas, the towns of Strathroy-Caradoc and Aylmer, and various smaller villages and townships.

The riding is considered a largely rural area with a significant agricultural presence, alongside increasing suburban development near the London city limits. The economy is driven by agriculture, manufacturing, and increasingly, services related to its proximity to London.

Electorally, the riding has historically been a stronghold for conservative parties, although shifts in demographics and political landscapes can influence election outcomes. The Member of Provincial Parliament (MPP) representing the riding is elected using the first-past-the-post electoral system. Information on current and past MPPs can be found on the Legislative Assembly of Ontario's website.
