This is a map of all the signalized intersections in Toronto (i.e. traffic lights) and the year they were first installed. The earliest traffic light in the city was at Yonge and Bloor in 1925. The points also have counts of vehicle and pedestrian volumes over an 8 hour period. These were each only recorded for a single day sometime between 2007 and 2016, so they should only be taken with a grain of salt!
