Traffic Signal Synchronization

As part of a five-year plan to improve traffic flow on Toronto streets, the City will be revaluating and coordinating approximately 1,000 traffic signals across the city. The project involves connecting traffic signals to the city’s Traffic Management Centre to allow for better timing and synchronization.

The plan also includes upgrades to Toronto’s traffic signal management system by the end of this year; installation of 100 traffic cameras on arterial roads to better detect problems; 13 additional message signs on the Don Valley Parkway and Gardiner Expressway and better management of the use of curb lanes.

In 2014, city staff will review and retime 15 signals along Yonge Street between the 401 and Eglinton as well as ten signals along Leslie Street between the 401 and Eglinton. These upgrades are scheduled to be completed by the end of 2014. To report problems related to signal coordination, you can dial 311 or visit to reach the city’s 24-hour help line!
