When I first arrived in Ottawa, I was surprised to discover that, just as in Brazilian cities, all the former streetcar lines had been dismantled, and many of their rights-of-way had been converted into paved roads for buses and cars.
As happened throughout Latin America, North America also saw a widespread shift from streetcars to buses beginning in the late 1950s, and Canada was no exception. In that country as well, an extensive network of tracks disappeared in favour of the automobile industry. This movement originated in North America and influenced the thinking of entrepreneurs throughout the rest of the Americas and Western Europe.
In Canada, larger cities such as Victoria, Vancouver, Calgary, Edmonton, Winnipeg, Halifax, Montréal, Québec City, and Ottawa also abandoned their streetcar systems. There were only a few exceptions worldwide (I will discuss them in a future post). Toronto was the most significant of them in the Americas: it maintained uninterrupted streetcar service and, across the continent, has the greatest number of kilometres of track, passengers, and vehicles.
Ottawa's system did not have the same fate. In 1948, the OER (Ottawa Electric Railway), the private company that operated the city's streetcars, proposed a fare increase. This led to a referendum in which residents voted in favour of municipalizing the transit system. As a consequence, the publicly owned OTC (Ottawa Transportation Commission) took control of the OER (Ottawa Electric Railway) in 1950. Since the system was outdated and the new company did not have the resources to expand the streetcar lines, the OTC decided to eliminate the system. This took place on May 1, 1959. The following day, the decommissioned vehicles paraded through the city for the last time.
This pattern of replacing rail-based transit with road-based transportation ultimately resulted in the choking of roadways as the number of automobiles increased.
Because of this problem, more modern streetcar systems used in Germany (Stadtbahn) and later in Nantes and Grenoble, France (Tramway), began to inspire initiatives to bring back the old streetcar, now rebranded as LRT (Light Rail Transit), as an alternative form of urban mobility.
The Trillium (2 and 4) and Confederation (1 and 3) Lines
In a way, as part of a movement to bring back the discontinued mode of transportation, Ottawa began making plans in the late 1990s to reintroduce an urban rail system to the capital.
In 2001, the municipal transit agency OC Transpo (originally the Ottawa-Carleton Regional Transit Commission), successor to the former OTC, introduced the eight-kilometre Trillium Line with diesel trains. In 2019, it introduced the Confederation Line, an LRT system (Line 1). Since then, Line 1 has been undergoing expansion as part of a major urban mobility project, partially restoring the mobility once provided by the streetcar network while extending rail service to more distant parts of the city.
The Trillium Line (Current Line 2)
Beginning in 2015, Bombardier's three Talent trains were replaced by six Alstom Coradia LINT trains. The system was then renamed the Trillium Line/Line 2, in anticipation of the construction of the future LRT Line 1, which opened in 2019.
Between 2019 and 2020, the Trillium Line connected with the newly opened Line 1 at Bayview Station, until the line was closed on May 2, 2020, for expansion southward. Line 2 then remained closed for nearly five years before reopening on January 6, 2025, with seven new Stadler FLIRT trains and additional stations.
The current route includes Bayview, Corso Italia (new station), Dow's Lake (formerly Carling), Carleton, Mooney's Bay (formerly Confederation), Walkley (new station), and Greenboro. From Greenboro, four additional stations were opened to the south: Southkeys, Leitrim, Bowesville (a park-and-ride station), and, farther south, the Riverside South neighbourhood, whose terminus is Limebank Station.
At South Keys, Line 4 branches off toward the city's airport (YOW), serving three stations: South Keys, Uplands, and Airport.
In total, the current Line 2 has 13 stations and extends for 19 kilometres, while Line 4 has two stations and extends for four kilometres.
Currently, Line 2 has thirteen diesel trains: six Alstom Coradia LINT units and seven Stadler FLIRT units. The trains are comfortable and spacious, providing a pleasant journey of approximately 40 minutes from one end of the line to the other. Although the LINT trains still operate on Line 2, they are used more frequently on Line 4.

The Confederation Line (Lines 1 and 3)
Line 1 opened in April 2019 with its current thirteen stations: Tunney's Pasture, Bayview, Pimisi, Lyon, Parliament, Rideau, uOttawa, Lees, Hurdman, Tremblay, St. Laurent, Cyrville, and Blair.
Unlike Line 2, Line 1 was designed for light rail vehicles (LRTs), and currently operates with Alstom Citadis Spirit trains.
Although technically classified as LRT, Line 1 differs from traditional systems because it operates on fully segregated rights-of-way, eliminating interaction with pedestrians and road traffic. This configuration gives Line 1 operational characteristics similar to those of a metro system, although it uses lightweight rolling stock.
Since April 2019, the line has been undergoing expansion in both western and eastern directions. Part of the existing Line 1 alignment will be shared with the future Line 3, meaning that both lines (1 and 3) will share tracks between Lincoln Fields Station in the west and Trim Station in the east, the future eastern terminus (the current terminus is Blair).

To the west, Line 1 will separate from Line 3 at Lincoln Fields Station and continue south to two additional stations, Iris and Algonquin, the future southwestern terminus.
Line 3, meanwhile, will continue westward from Lincoln Fields through four additional stations: Queensview, Pinecrest, Bayshore, and finally Moodie, its western terminus.

The O-Train is just one example of the modern return to streetcar-based transportation, as cities try to make up for some of the wrong choices of the past. In the years ahead, Ottawa will certainly need new lines and other forms of rail transportation to connect its different regions more efficiently. And, really, the same lesson applies to any major city.
