The exhibition Déviation is an initiative of the Société de développement commercial – Les Quartiers du Canal and a creation of Art Souterrain. Its goal is to revitalize Notre-Dame Street West artistically during the construction period.

The exhibition is composed of three sections: the windows in which contemporary artworks are installed to beautify these spaces, the in situ works displayed on various sites of the building site, and the performances, real unprecedented artistic events to discover at progress of the work.
