Middlesex County is situated in Southwestern Ontario. The county is bordered by Huron and Perth counties on the north, Oxford County on the east, Elgin County on the south, and Chatham-Kent and Lambton County on the west.
The seat is the city of London, though the city is politically independent from the county. Middlesex County is composed of eight incorporated municipalities: Adelaide Metcalfe Township, Lucan Biddulph Township, Municipality of Middlesex Centre, Newbury Village, Municipality of (township) North Middlesex,
Municipality of (township) Southwest Middlesex, Township of Strathroy-Caradoc, and the Municipality of (township) Thames Centre.
Middlesex is a sprawling area bountiful with diverse outdoor experiences for both the adventurous and the leisurely.
