1969: The NHL announces that it will expand from 12 to 14 teams for the 1970-71 season.

One of the teams will be based in Vancouver, which has been promised a team after a local group is not permitted to buy the Oakland Seals and move them. Candidates for the other new franchise include Atlanta, Baltimore, Buffalo, Cleveland, Kansas City and Washington. Buffalo is awarded the second franchise, to be owned by brothers Seymour Knox III and Northrup Knox.

Buffalo and Vancouver are placed in the East Division, with the Chicago Blackhawks moving to the West Division.
