I know there's some Franchise History threads for some of the minor pro leagues on here so I figured I'd do one that covers all the teams in the WHL, OHL and QMJHL. I'm using 1970 as a starting point because that's when the major junior level was officially created with the three leagues competing for the Memorial Cup.
