easily leave since no contractual commitment was required. In 1950, the CAHA decided that its five best calibre senior leagues would compete for a new trophy at a higher level than the Allan Cup. The Alexander Cup became the championship trophy of the Major Series. The 1951 Valleyfield Braves and the 1952 Quebec Aces won the Alexander Cup. The Ottawa Senators contested that according to the Major Series agreement, the handling of player eligibility questions and infractions of rules should be done by the CAHA instead of the QAHA. CAHA president W. B. George conducted discussions in December 1952, which resulted in recommended changes to the QSHL constitution and assertion of CAHA control over the Major Series. In May 1953, the league decided to leave the CAHA by resigning from the QAHA, which was itself under suspension from the CAHA. After leaving the CAHA, the team owners voted to become professional to protect their player contracts. However, QSHL players who had signed forms with NHL clubs to play professionally, could not sign with the new QHL teams. The players who signed QHL contracts became QHL team property and their contracts could be sold or traded to NHL or other professional leagues. The QHL disbanded following the 1958–59 season, with the Hull-Ottawa Canadiens, Montreal Royals and Trois-Rivières Lions going to the Eastern Professional Hockey League and the Quebec Aces heading to the American Hockey League.
