The Alexander Cup was presented by its namesake, the Viscount Alexander as the 17th Governor General of Canada.

The Alexander Cup was only in competition for 4 seasons - 1950-51 to 1953-54.

The Canadian Amateur Hockey Association / CAHA originally wanted a higher level of senior ice Hockey competition since a small group of teams were dominating the Allan Cup playoffs.

At the 1950 general meeting, the CAHA decided that its 5 best calibre senior leagues, the Western Canada Senior Hockey League, the OHA Senior A League, the Quebec Senior Hockey League, the Maritime Major Hockey League, and the Cape Breton Senior Hockey League would compete for a new trophy.

In November 1950, they announced the Alexander Cup would be the championship trophy of the new Major Series.

CAHA president W. B. George later announced that the Alexander Cup was to be retired due to the lack of interest.

By October 1953, four of the original 5 leagues which competed for the trophy had withdrawn with only the Maritime Major Hockey League remained.
