Within Ontario and prior to 1997, Highway2 began in Windsor at the interchange between the E. C. Row Expressway and Highway3 (Huron Church Road), where it also met the northern terminus of Highway 18. It followed the expressway east through Windsor, with the divided highway transitioning to an urban arterial road near Lesperance Road. It travelled nearby the south shoreline of Lake St. Clair as it bisected Emeryville and Belle River before curving south briefly. It then turned east and travelled through a rural setting to Tilbury, where it met Highway401 at two interchanges (Exit56 and 63). Crossing from Essex County to Kent County, the highway curved northeast and passed through Chatham—where it intersected Highway 40—Louisville and Thamesville—where it intersected Highway 21—before entering Middlesex County near Bothwell—where it met Highway 79. Between Chatham and Delaware, Highway2 travelled roughly parallel to and north of the Thames River. It passed through the communities of Wardsville, Strathburn—intersecting Highway 76 and Highway 80—and Melbourne before encountering an interchange with Highway 402 and crossing the Thames River. Within Delaware, the highway intersected Highway 81 and turned east. At Lambeth it met Highway 4 and the two highways travelled concurrent northeast into London. In downtown London, Highway2 and Highway4 parted at the intersection of York Street and Richmond Street, with Highway2 continuing east along the former. It intersected the northern end of Highway100, now known as the Veterans Memorial Parkway. While the route was south of the Thames River between Delaware and London, it continued east along Dundas Street between the two branches of the river between London and Woodstock, intersecting Highway 19 between the two in the community of Thamesford. At Woodstock, Highway2 intersected Highway 59 and met Highway401 at an interchange near the split with Highway403. It then continued east, becoming parallel with the latter towards Hamilton. It intersected with Highway 53 at Eastwood and passed through the communities of Creditville, Gobles and Falkland before entering Paris. Within Paris, the highway intersected Highway 24A and met the western terminus of Highway 5, with which it remained within through to Toronto. Highway2 branched southeast through Brantford, where it intersected Highway 24 and became concurrent with Highway53 before meeting the end of Highway403 at Cainsville; Highway 54 branched south from there. Before 1997, Highway403 was discontinuous between Cainsville and Ancaster, intersecting and merging into Highway2 at both locations. The combined Highway2/53 travelled east through Alberton, before
