The first phase of the Toronto subway was completed 1954 as the first subway line in Canada, with sleek but austere and repetitive station architecture, influenced by the International Style. Yet the opening of the Montreal Metro opened in 1966 proved to be more architecturally significant in Canada because its individual stations each contained unique Modernist architecture with expressive uses of colour, form, and materials by different architects and incorporated works of art to enhance the experience of using the system. This influenced Toronto to take a similar course with its Spadina line by 1978, commissioning Arthur Erickson and several Canadian firms and artists. Montreal continued upon its legacy of unique station architecture in expanding its system. Vancouver's Skytrain rapid transit system relied on modern minimalist designs from its beginning in 1985, with some design variation and artwork in terms of the stations in the system which have been added since its opening.
