After World War II, Canada still used the old Dominion flag and used Great Britain's constitution. In 1967, Canada developed the Maple Leaf flag and in 1982, Canada finally developed their own constitution. For the first 30 years after World War II, Canada was swamped with rock and roll music, feminism, communism, and gay rights activists. Homosexuality was later decriminalized in the year 1969. By the year 1975, universal healthcare was widely accepted by all Canadians.
