White Line (Montreal Metro)

The White Line (French: Ligne blanche), also known as Line 7 (French: Ligne 7), was a proposed line of the Montreal Metro that never made it past its planning stage. The White Line was first proposed by the Commission de transport de Montréal (CTM) during the initial planning for the Montreal Metro in 1953, and in 1970 the Communauté urbaine de Montréal (CUM) proposed an extension of the Green Line to Montréal-Nord.
