The first cloverleaf interchange in Canada opened in 1937 at the junction of the Queen Elizabeth Way (QEW) and Provincial Highway 10 in Port Credit, Ontario (now a part of Mississauga, Ontario). As originally built, Highway 10 passed over the QEW. In 1962, the interchange was rebuilt with sub-collector roads along the QEW, and the orientation was also changed so that Highway 10 then passed under the QEW. The interchange was further modified between 2008 and 2010 by removing all but one loop ramp, creating a partial cloverleaf/diamond hybrid.
