Document 12: Canadian folk music: Canadian folk music has a long history, dating from the 16th and 17th century, mostly derived from the music of early settlers; much earlier for the music of indigenous people. Folk music thus differentiates between traditional and contemporary. Many of Canada's most influential folk artists emerged in the contemporary folk music era, notably Bruce Cockburn, Buffy Sainte-Marie, Ferron, Gordon Lightfoot, Joni Mitchell, Kate & Anna McGarrigle, Leonard Cohen, Murray McLauchlan, Stan Rogers, Valdy, Penny Lang and Wade Hemsworth. In the 1970s, chansonniers grew steadily less popular with the encroachment of popular rock bands and other artists, and many of the folk clubs, such as the Montreal Folk Workshop, and groups such as The Raftsmen, the Mountain City Four and, eventually, The Travellers, that had served to foster the mid-20th century revival closed down. Some new performers did emerge, however, including Jacques Michel, Claude Dubois, and Robert Charlebois. The Canadian Folk Music Awards are presented annually to musicians carrying on in the tradition.
