, after which it is named. It is patrolled by the Toronto Police Service

The parkway was the second expressway to be built by Metropolitan Toronto (Metro). Planning for it began in 1954, the year of Metro's formation, the first section opened in 1961 and the entire route was completed by the end of 1966. South of Bloor Street, the expressway was constructed over existing roadways. North of Bloor Street, the expressway was built on a new alignment through the valley, requiring the removal of several hills, the rerouting of the Don River and the clearing of green space. North of Eglinton Avenue, the expressway follows the former Woodbine Avenue right-of-way north to Highway 401. The parkway operates well beyond its intended capacity of 60,000 vehicles per day and is known for its daily traffic jams; some sections carry an average of 100,000 vehicles a day. Planned as part of a larger expressway network within Toronto, it was one of the few expressways built before the public opposition which cancelled many of the others.
