Designed by Longpré, Marchand, Goudreau, Dobush, Stewart, et Bourke, it is a normal side platform station built in tunnel. The central mezzanine gives access to the entrances diagonally across from one another at the corner of rue de Cadillac and rue Sherbrooke. The hallways to these entrances feature complementary murals by Jean Cartier.
Origin of the name
This station is named for rue de Cadillac, itself named after Antoine Laumet, dit de La Mothe sieur de Cadillac (1658–1730) — a colourful French explorer of New France who founded Detroit, Michigan and commanded it from 1701 to 1710. Despite his name being pronounced as \ka.di.jak\ in French, the station is pronounced as \ka.di.lak\. The STM has corrected this pronunciation issue as of August 2022 [1].
