The Veterans Memorial Parkway in London, Ontario, has intersections instead of interchanges, and thus is considered an expressway and not a freeway. It was originally designed with sufficient right-of-way to be built as a full freeway, but a lack of funding forced it to be built with at-grade intersections. Similarly, the Hanlon Parkway in Guelph and Highway 40 in Sarnia, Ontario were originally opened with intersections in lieu of interchanges, save for the couple grade-separated interchanges. Regional Road 420 in Niagara Falls is also an expressway. While Allen Road and Highway 400 were originally full freeways, their extensions (for Allen Road to meet Sheppard Avenue and Dufferine Street, and the 400 South Extension which became Black Creek Drive and handed over to Metro Toronto upon completion) were built as expressways with at-grade intersections.
