Canadian blues records have been made on a number of labels, including mainstream labels that are mainly associated with pop or jazz music, and smaller independent labels that specialize in acoustic or roots music. One of the oldest Canadian labels which specializes in blues and related musics is Stony Plain Records, a record company based in Edmonton, Alberta which was established in 1976 by Holger Petersen. The label has released over 300 albums of "roots" music styles, such as blues, classic R&B, folk, country, bluegrass, and rock and roll. Jerry Wexler, one of the founders of Atlantic Records, states that "Stony Plain, as an independent company, is an endangered species in a dangerous world – and a source of wonderful music."
