Designed by Papineau, Gérin-Lajoie, and Leblanc, it is a normal side platform station, built in open-cut under boul.

Its mezzanine floats within the open-cut volume, supported by pillars and beams, and contains ticket barriers at either end with the fare-paid zone in the centre.

A circular theme is present throughout the station's decor: there are bright single colour circles on light panels surrounding the advertising posters, circles in the marble of one entrance, circular tiles on the floor and walls, but the best-known works of art in the station, and the main artwork, are a series of 54 large circles (of which 37 remain) by Jean-Paul Mousseau, one of the few artworks to be integrated into the architecture of the original network rather than commissioned later.

Created in collaboration with ceramist Claude Vermette, these circles, set in floors and walls throughout the station, are mainly in tones of orange or blue streaked with other colours.

He is best known for creating London's police department while Home Secretary, thus giving them their nickname of "Bobbies".
