Palais des congrès de Montréal

Place-d'Armes station is located in the building with an underground connection to and from the convention centre.

Some of the land for Palais des congrès was expropriated from Chinatown, Montreal, along with building of Complexe Guy-Favreau. Plans to expand the Palais began in 1997. It was expanded from 1999 to 2002, doubling its capacity from 92,000 square metres (990,000 sq ft) to 184,000 square metres (1,980,000 sq ft). The expansion was designed by a consortium of three firms: Tétrault Parent Languedoc; Saia Barbarese Topouzanov; and Aedifica, with Hal Ingberg.

This was the venue for the 2022 United Nations Biodiversity Conference, which led to the Kunming-Montreal Global Biodiversity Framework.
