Although my PhD research focuses rather narrowly on environmentalism in Toronto, I am more broadly interested is how the movement came together across Canada. While the literature on this subject is still in its infancy, an early and indispensable study exploring the Quebec story is Jane Barr's "The Origins and Emergence of Quebec's Environmental Movement: 1970-1985." Completed in 1995, this MA thesis argues that "Unlike its parallel in the United States, Quebec's movement had few historical or ideological links with efforts to preserve wilderness and it developed social - rather than nature - protection principles." An interesting argument that is worth a perusal if you're interested in the subject.
