Remembering Toronto’s First Automated Traffic Lights: August 8: Snapshots in History
The City of Toronto’s history of traffic management has had some interesting milestones, beginning with the institution of Toronto’s first automated traffic lights at Bloor Street and Yonge Street, the heart of the downtown city core, on August 8, 1925.
Page one of the August 8, 1925 issue of the Toronto Daily Star offered readers an article with the following headline: “FLASHING LIGHTS OPERATE TRAFFIC BLOOR AND YONGE: New Electrically Controlled Signal System is Being Given Trial: MANY BLUNDERING: But Motorists Are Quick to Grasp Idea and Find It Facilitates Travel”. Here is an excerpt from that article:
“Vehicular traffic, automatically controlled, made its first appearance on Toronto streets to-day when the new electrically operated signal was set into use on the corner of Bloor and Yonge streets. During the morning…many motorists ran into trouble when they failed to see the shining lights perched fourteen feet above the ground which have replaced the stalwart policeman who formerly controlled the signal in the centre of the street…Under the new system which has been adopted by more than 200 cities of the United States and by several cities in Canada, lights of three different colors, red, yellow and green, have been placed on the corner poles and all these are worked automatically from a signal box on the southeast corner of the intersection. The lights go off and on at half minute intervals, that is the lights directing north and south bound traffic are red for thirty seconds, yellow for fifteen seconds and then green for thirty seconds…The system which was installed by the Crouse-Hinds Company of Toronto has already been installed in Windsor, London, Ontario, and Hamilton, London using it at one intersection, Windsor at six and Hamilton at two…Should it be equally successful on the corner of Yonge and Bloor it is not improbable that all the main intersections will soon be governed by the same system…”
Next to the article on page one was the headline “Traffic Control by Lighting System” over three juxtaposed photographs, namely of the control box at the intersection responsible for controlling the light depicted on each corner of the intersection, and another photograph depicting three horizontally-displayed automated and elevated traffic lights with the accompanying message of “No Left Turn” emblazoned below, while the final photograph depicted a close-up of those same traffic lights with the same “No Left Turn” message. A short article (also on page one) entitled “TORONTO TRIES OUT ELECRICALLLY-CONTROLLED TRAFFIC” was published right below the third photograph. Here is an excerpt from that article:
“Control of motor and pedestrian traffic by electrically controlled lighting system was inaugurated in Toronto to-day, the system being given a trial at the intersection of Bloor and Yonge streets…motorists found the system most beneficial to facilitating speedy crossing of the corner, although…many were caught unawares because they did not know the new system has been installed…”
The August 8, 1925 issue of The Globe newspaper carried an article on page thirteen entitled “AUTOMATIC SIGNALS WILL OPERATE TODAY AT BLOOR AND YONGE: Vehicular and Pedestrian Traffic to Be Regulated by Lights: TESTS MADE LAST NIGHT”. Here is an excerpt from the article:
“Automatic traffic-regulating signals will be in operation today at the intersection of Bloor and Yonge Streets. A test of the “silent” traffic signals were made last night at this intersection. Chief Dickson and Inspector Martin were interested spectators during the time the tests were being made…The new signals will be placed at all four corners of the street…automatically operated from a control box. The signals will direct traffic every 30 seconds each way, with an allowance of three seconds to permit standing cars to get ready to move on…These signals…are equipped for operation from a master tower, which could be erected in a central location, should Chief Dickson decide to place them on all the major thoroughfares…Chief Dickson expressed the desire that pedestrians comply with the traffic regulations…traffic could be speeded up and fewer accidents would result…The introduction of the semaphores…would make more traffic constables available for other police duties…"

Then click on “History of Traffic Systems in Toronto” to review the City of Toronto’s experiences in employing different technologies. During June 1963, Metropolitan Toronto installed “the world’s first full-scale, real-time, automatic traffic control computer”. However, problems hampered its full implementation until 1964. The traffic computer was having problems in the mid-1970s and the decision was made in 1978 that a replacement traffic control system was required. The resulting traffic control centre was constructed within the Sheppard Subway Station and became functional in the early 1980s.
