Provincial Instructor in Road-Making from 1896 to 1900 and Director of the Office of the Commissioner of Highways from 1900 until 1910. He was tasked with training Provincial Road Building Instructors. These instructors worked to establish specifications for the almost of county- and township- maintained roads. The name of the office was changed to the Commissioner of Highways and transferred to the Department of Public Works in 1900. By 1910, the office was generally referred to as the Highways Branch. In 1910, W.A. McLean, Provincial Engineer of Highways, succeeded A.W. Campbell as the director of the Highways Branch. Under considerable pressure from the Ontario Good Roads Association and the ever-increasing number of drivers, which the province itself licensed at that time, the Department of Public Highways was formed in 1916 with the goal of creating a provincial highway network. The department assumed all the functions of the Highways Branch. The department assumed its first highway, the Provincial Highway, on August 21, 1917. On February 20, 1920, the department assumed several hundred kilometres of new highways, formally establishing the provincial highway system. Although established as a separate department, the Department of Public Highways shared ministers with the Department of Public Works prior to 1931 and seems to have been in a quasi-subordinate relationship with this department. In 1916, the Motor Vehicles Branch was established within the Ontario Department of Public Highways. Prior to this, responsibility for the registering and licensing of motor vehicles rested with the Provincial Secretary (a responsibility it held since 1903). Although there are references to motor vehicle licensing and registration between 1916 and 1918, there is no mention in the Annual Reports of what agency actually performed this function; it is, however, likely that it was a form of, or precursor to, the Motor Vehicles Branch. In 1919, a Registrar of Motor Vehicles, as head of the Motor Vehicles Branch, is clearly identified. In 1917, the Provincial Highway Act was passed, giving the department authority to maintain and construct leading roads throughout the province as provincial highways (designated King's highways in 1930). The Department of Public Highways was renamed the Department of Highways in 1931 and was assigned its own minister, Leopold Macaulay, though Macaulay later held both portfolios in 1934. In 1937, the Department of Northern Development, previously responsible for highways in the northern parts of the province, was merged into the Department of Highways, thus
