An architectural marvel in itself, the Palais des Congrès de Montréal spans across 2,00,000 square feet (19,000 square meters). Inaugurated in May 1983, this glass structure comprises exhibition areas, loading docks, and meeting rooms. The center plays host to conferences, meetings, seminars, and other corporate events. The Montreal International Auto Show and Montreal Comiccon take place at this center annually. In the past, Palais des Congrès de Montréal has been host to United Nations Climate Change Conference and 67th World Science Fiction Convention.
