The riding of Mississauga–Streetsville saw its boundaries shifted ahead of the 2015 election as a part of a riding redistribution process that saw new ridings created and several existing riding boundaries changed. Mississauga—Streetsville had the southeastern portion of the riding incorporated into the new riding of Mississauga—Malton and it picked up the northwestern part of the old Mississauga—Brampton south.
