St-Laurent Station is located underground adjacent to the St. Laurent Shopping Centre. This station, much like it was in the past as a bus Transitway station, is a multi-level station, with the train platforms and concourse located underground, and the bus loop situated above.
This station primarily serves the St. Laurent Shopping Centre as well as serves as an important hub for commuters reaching businesses on St. Laurent Boulevard and as well as the many residential areas nearby. It is interesting to note that St-Laurent station is OC Transpo's original and first underground transit station.
As mentioned above, the train is located underground, with access provided by the above ground station building, as well as through the indoor connection to the shopping mall. An additional access is provided by a pedestrian pathway that starts just behind the eastbound track's far end and exits at Tremblay Road, granting easy access to residents of Eastway Gardens to the station.
Large expansive and immersive murals decorate and add colour and ambience to the stations platform level. In such an open and vast space, these murals definitely add much needed colour and warmth to the station.
The stations layout is that of side platforms. Interestingly, the two platforms are not connected directly, and require passing through the fare gates to switch from one platform to the other. An overhead walkway (still located in the underground station cavern, and a hold-over from its former vocation as a bus Transitway station) allows access between both platform entrances.
St-Laurent Station is overall a good station but does suffer from some design limitations as the bus loop located above needed to be maintained open and functional during construction and conversion from bus to rail transit. As a complete rethinking and redesign would have surely affected bus operations above, engineers and designers did their best to improve the station. The biggest drawbacks are the narrow accesses to the stairs and escalators from the concourse walkway level, the 2 small elevators that reach the bus platform, and the massive ceiling that comes off a bit as unfinished. These points can be easily looked past, but it does remain unfortunate that they exist.
St-Laurent Station is unique in that it is currently the only station outside of the downtown core to be located underground, much as it was in the past as a bus Transitway station. As mentioned earlier, it is the original and first underground transit station on OC Transpo's network, originally built in 1987.
