Lorne Park is in southwest Mississauga, with Lake Ontario as its most southern boundary. The area was once a large park/summer resort, and then became a cottage community until amalgamation into Mississauga in 1968. Lorne Parke now features very expensive properties and mansions, especially in the Lorne Park Estates area, as well as townhome condos, and a variety of styles of single-detached homes.
