The Middle Road was the name for a historic highway in the Canadian province of Ontario, which served to link the cities of Toronto and Hamilton. The name was used between 1931 and 1939, after which the road became the northern section of the Queen Elizabeth Way. It borrowed the name of Middle Road from a concession road in Toronto Township between 1st Concession South and 2nd Concession South during the early 1800s. The Middle Road provided the blueprint for Highway 401, an expressway that became a key contributor to the economic success of Ontario.
