Major Junior (1970 to Present):
The champions of the Ontario Hockey League, Quebec Major Junior Hockey League, and Western Hockey League, along with a host club (since 83), have met each spring (except 71) in a round-robin series with the two top teams playing off in a sudden-death game to determine the Memorial Cup champions. Since 75, the Canadian Hockey League (CHL) has been the governing body for Major Junior Hockey in Canada. Its precursor was the Canadian Amateur Hockey Association (CAHA).
