The original station was designed by Duplessis, Labelle et Derome.
It is a normal side platform station built in a tunnel, with a mezzanine on its southern end giving access to several exits, including underground city access to the Tour Jean-Talon.

With the construction of the Blue Line in 1986, the station was greatly expanded.
Two large volumes were dug, one on either side of the original station, giving access to the stacked Blue Line platforms below.
This portion of the station was designed by Gilbert Sauvé, and included artistic tiling designs by the architect as well as a large mural by Judith Bricault.
Another access was built leading to the Plaza Saint-Hubert, connecting to the eastern volume by an automated entrance.
The Blue Line platforms were inaugurated on June 16, 1986.

Jean-Talon is the only one of Montreal's four transfer stations not to have been built that way from the beginning.
The Orange Line platform is accessible by elevator.
The Blue Line has no elevator.

The station has 4 entrances:
7100 Berri Street
430 Jean-Talon Street E.
522 Jean-Talon Street E.
780 Jean-Talon Street E. (automated entrance)
