A Quick Early History of Toronto’s First Traffic Signals and The ‘Right on Red’ Rule

In the first half of the twentieth century, automobiles had quite an impact on the streets of Toronto. In 1913, there were 17,000 cars in Toronto; by 1923, the number grew to about 50,000 cars. New rules and technologies were adopted to better manage and regulate how motorists behaved, especially concerning the other users of the road and their safety.

Traffic Lights: A Most Beneficial System

On August 8, 1925, Torontonians were introduced to their first set of automated traffic signals. The new ‘semaphores’ were set up at the busy intersection of Yonge Street and Bloor Street on a trial basis and changed the history of Toronto’s streets forever. It was at least three years in the making, with Toronto Chief of Police Samuel J. Dickson advocating for and finally receiving the system in that time.

Before traffic lights, intersections were regulated by traffic policemen. In the 1910s, this was done largely through hand signals, whistles, and yelling. In 1920, a new ‘semaphore’ was piloted (again at Yonge and Bloor) which consisted of the officer controlling a staffed sign with the words “STOP” and “GO” written on them. The officer rotated the sign to control the flow of traffic. If one peruses archival photos of highly trafficked Toronto intersections, it is common to see a police officer amid the action.

The new traffic lights were an overall success. Automated signals were installed on major junctions along Yonge Street, Bloor Street, and Danforth Avenue, and in suburbs such as East York within the next few years after their introduction. As an example of the new semaphores’ impact, The Globe reported in December 1929, the intersection of Bloor Street and Keele Street had an average of 4 or 5 accidents a day before automated signals were installed there in 1927; there were no accidents after that point.

Police Chief Dickson even dreamed of a master tower at Yonge and Queen to control all the lights in the city. The idea became a reality at the end of 1926. There was even synchronicity within the lights: a motorist travelling straight on Danforth Avenue between Main Street and Broadview Avenue in 1928 was able to meet all green lights if he travelled at 19 or 20 miles per hour; any slower or faster, the driver would hit a red light (the speed was 18 miles per hour downtown).

Of course, several early reports indicated that the new lights were not all good. Even the Mayor weighed in, saying to the Police Chief in October 1925 that officers were still stationed at the Yonge and Bloor ‘experiment’, seemingly defeating the Chief’s goal of having the technology free up more policemen from traffic duty. Sometimes they did not function properly or at all, as The Globe reported in July 1928 of the new, often “stuck” Dundas Street East signals. But despite these complaints, the lights were there to stay; 96 signals were installed in Toronto by the end of the 1920s.

The ‘Right on Red’ Rule

One of the most interesting impacts of the rise and success of traffic lights was a ‘new’ law that permitted a motorist to make a right-hand turn against a signal that would otherwise make him wait at the intersection. This is the ‘right on red’ rule. On March 22, 1927, Police Chief Dickson announced the reinstatement of the permission, indicating that it was actually in effect “some time ago” and the success of the new lights could now allow for it once more. It is unclear what period the rule was previously in place or why it disappeared, although reckless driving at unmanned intersections is a theory for its removal.

The ‘right on red’ permission was not without controversy, even with the police itself. The organization vowed to watch right-turning drivers and warned them to prioritize the safety of pedestrians who had the right of way to cross the street.

In July 1928, new Police Chief D.C. Draper reiterated motorists were allowed to turn right at a “hostile” light, having “regard” of other cars and pedestrians who have the right of way. However, in March 1929, Draper advocated against the rule. In a report by the Traffic Committee, which monitored Toronto streets for more than a month for traffic improvements, the Chief suggested, among other items, the discontinuance of “the present practice of motorists making a right-hand turn against the red light” or “otherwise give them a warning that the pedestrians have the right of way, and that right-hand turns against a red signal are only allowed when care is exercised”. The Board of Control ultimately went against the Chief and retained the rule while reiterated motorists were responsible for pedestrian safety.

Interestingly, in Hamilton, which was the setting of Canada’s first traffic lights just two months before Toronto’s semaphores were installed, the Traffic Committee wanted to abolish the rule which allowed right-hand turns on red lights in 1933. Oddly, it was met with disapproval from the Ontario Department of Highways. The by-law ultimately remained.

Despite many calls in Toronto in the decades since to remove the permission for good, the Highway Traffic Act currently upholds it in Ontario:

s. 144 (19) Despite subsection (18) and subject to subsection (14) [Green Arrows], a driver, after stopping his or her vehicle and yielding the right of way to traffic lawfully approaching so closely that to proceed would constitute an immediate hazard, may,

(a) turn to the right; or

(b) turn to the left from a one-way street into a one-way street,

without a green indication being shown.

To Stop or Not?

Another interesting question arose on the requirement to stop before turning right. In November 1927, a person writing into The Toronto Daily Star‘s “Voice of The People” section was puzzled by the different standards of when there was a stop sign at an intersection (which he interpreted as ‘stop means stop’) and when there was a policeman with a semaphore (which he interpreted as ‘stop means stop sometimes‘). The editor replied that when an officer was holding the semaphore, he supervises traffic and allows right turns without stopping. When there is no officer, all cars must stop.

Within Toronto City Hall, the issue of drivers legally passing through a red light to turn right was debated for several years. In July 1929, Toronto’s Traffic Committee suggested an amendment of certain by-laws to protect pedestrians, including motorists were to come to a stop before making a right-hand turn against the red light. It did not seem to have made an impact. In December 1933, the idea was raised again, this time proving more successful. The Board of Control favoured a change to the by-law so that every driver must come to a full stop before making a right turn at an intersection controlled by automatic traffic signals. The change seemed to be spurred by complaints that motorists were not heeding the way to pedestrians and “showing no consideration for the pedestrian”. City Council adopted the change on December 12th of the year, subject to approval by the Department of Highways.

Inexplicably, the rule was changed back only four months later. In April 1934, the by-law requiring motorists to make a complete stop before a right turn at a red light was rescinded. The Board of Police Commissioners instructed police officers to safeguard the rights of pedestrians once more.

It is unclear when exactly the law reverted once again, but it seems the matter was not closed. The idea seemed to be backed in other circles, too. In a February 1934 meeting of the Ontario Motor League, a suggestion was advanced that those turning right in the province should come to a full stop at both a red land green light. In 1938, a reader of The Globe and Mail expressed his displeasure in the lack of pedestrian rights in motorists not having to stop before right turns. A decade later, in July 1948, the same newspaper rode along with Toronto Traffic Safety Council Inspector Vernon H. Page in a motor car as he pointed out traffic infractions, including those failing to come to a full stop before a right turn, meaning by this point the law was reinstated.

Today, of course, a red light does indeed mean ‘stop’ in all contexts, as the Highway Traffic Act so states:

s. 144 (18) Every driver approaching a traffic control signal showing a circular red indication and facing the indication shall stop his or her vehicle and shall not proceed until a green indication is shown.

“Old” Streets of Toronto

Across the map of Toronto, there are several “Old” versions of major streets: Old Yonge Street, Old Leslie Street, et cetera. These are smaller and certainly older streets that predate yet still exist alongside their longer, newer counterparts.

How old are these “old” streets anyways? Why were they built as they were in the first place? Why were they replaced?

Here are five examples of “Old” Toronto Streets and their histories:


1. Old Yonge Street

Year rerouted: 1835

When Yonge Street was laid out in the 1790s, it was not the continuous straight path we think of today. The sheer length of the street almost welcomed obstacles. At York Mills, the challenging topography around the West Don River caused it to divert east just south of York Mills Road. It curved north and back west to join the original course. In 1835, the street was realigned and straightened. It seems in the 1920s, Yonge Street was re-routed again slightly to the west to allow for better automobile navigation.

Source: Globe & Mail Archives.

Today, the old, “orphaned” course remains as part of Mill Street and Old Yonge Street. Old Yonge’s narrow, curvy course in parts maintains a rural quality. While at one time Yonge and Old Yonge once connected at its north end, this connection is now a roundabout. Finally, because of its length in the province, there are other Old Yonge Streets in Thornhill and Aurora.

2. Old Sheppard Avenue

Year rerouted: ~1934

Sheppard Avenue once existed in two separate sections on either side of the Scarborough-North York border. A traveller wishing to travel east or west through the two streets had to jog about 300 metres on Victoria Park to reach the other section. In 1934, the two roads were joined through a curving road running from just past Woodbine Avenue to the lower street in Scarborough. The move was the idea of Ontario Premier George S. Henry whose estate stood where the new Sheppard Avenue connection ran.

Today, the orphaned North York section of the old road now exists as residential Old Sheppard, albeit with small parts removed around Highway 404.

3. Old Lawrence Avenue

Year rerouted: ~1961

Lawrence Avenue is and was one of many streets which was impact by Toronto’s ravines. West of Victoria Park Avenue, Lawrence once took an interesting route across the East Don River Valley. Like Sheppard Avenue, there were two sections of the street: the Scarborough section which exists today and a North York section. The North York section jogged up Victoria Park over the Canadian Pacific Railway, ran briefly next to the track, and continued west for 1.5 kilometres. From here, it took a rather curvy route south down the East Don Valley, crossed the Don River via a bridge, and curved back north and west before continuing towards Don Mills Road. Presumably, this was easiest way in the 19th century to navigate the valley.

In 1961, Lawrence Avenue was straightened with a road directly connecting Victoria Park and Woodcliff Place, curling northwest from Scarborough with several new bridges to accommodate the Don River and CPR.

Today, the orphaned old road exists as roughly as part of Roanoke Road and, more famously, a short access road to the East Don Trail named Old Lawrence. The remaining section west of the river along with the old bridge itself have been lost.

4. Old Leslie Street

Year rerouted: ~1968

Like Lawrence Avenue, Leslie Street’s course at one time also had to divert around the East Don River. Also of 19th-century origin, a traveller going north on Leslie had to turn west for a short distance and then northwest for about 500 metres to meet with Sheppard Avenue. There was then a jog east on Sheppard, which included a bridge over the river and finally a left turn to travel north again.

In the 1950s, with the construction of Highway 401, Leslie Street was altered to curve through the highway, but the course has otherwise remained the same. In 1968, the street was reconfigured again to join with Sheppard more directly. The Don River was also straightened and a new bridge was constructed which spanned the entirety of the new four-way intersection.

Today, the old course remains as Old Leslie Street, albeit a shorter version of the original route is available today to the public. It joins the new Leslie Street via Esther Shiner Drive. South of that street, there are City facilities. North of Esther Shiner, Old Leslie serves the Leslie Street TTC Station before it crosses over Sheppard via an overpass. It then curls back down to join the street (there is also a parking lot with an entrance to the East Don Parkland trail).

5. Cummer Avenue

Year rerouted: ~1969

The original course of Cummer Avenue west of Leslie Street was an 1819 construction. The street was laid out as a side road from Yonge Street by the Cummer family to access their holdings (a mill and camp) near the East Don River. When it approached the valley, it curved down to roughly follow the river’s course. It crossed the river via a bridge and eventually the railway tracks at a level crossing. Finally, it terminated at Leslie Street.

By 1969, the street was rerouted to curve north away from the river (which looks to have been straightened around this time as well). The street passed through a new wider bridge over the Don River and then under a railway overpass before eventually becoming McNiccol Avenue at Leslie Street.

The old, orphaned course still exists in parts. The curved section lives on as part of the East Don Parkland trail, although not all of it follows the old path. The old bridge is in situ as well. The trail travels east through the hydro corridor where it terminates at the railway tracks. On the other side, Old Cummer Go Station and a hundred-metre long Old Cummer Avenue hold the old name.
