The Ministry of Transportation (MTO) is the provincial ministry of the Government of Ontario that is responsible for transport infrastructure and related law in Ontario, Canada. The ministry traces its roots back over a century to the 1890s, when the province began training Provincial Road Building Instructors. In 1916, the Department of Public Highways of Ontario (DPHO) was formed and tasked with establishing a network of provincial highways. The first was designated in 1918, and by the summer of 1925, sixteen highways were numbered. In the mid-1920s, a new Department of Northern Development (DND) was created to manage infrastructure improvements in northern Ontario; it merged with the Department of Highways of Ontario (DHO) on April 1, 1937. In 1971, the Department of Highways took on responsibility for Communications and in 1972 was reorganized as the Ministry of Transportation and Communications (MTC), which then became the Ministry of Transportation in 1987. The MTO is in charge of various aspects of transportation in Ontario, including the establishment and maintenance of the provincial highway system, the registration of vehicles and licensing of drivers, and the policing of provincial roads, enforced by the Ontario Provincial Police and the ministry's in-house enforcement program (Commercial vehicle enforcement). The MTO is responsible for: 10.4 million vehicle registrations 8.5 million driving licences 55 driver examination centres and 37 travel points (both operated by Plenary Serco (PS) DES, as DriveTest Centres) 281 privately owned Driver and Vehicle Licence Issuing Offices across the province Metrolinx (responsible for GO Transit, Union Pearson Express, and Presto card) 16 525 kilometres of provincial highways ServiceOntario kiosks Commercial vehicle enforcement program vehicles and infrastructure (varies annually).
