The Canadian Amateur Hockey Association (CAHA) revised its definition of amateur and broke away from the Amateur Athletic Union of Canada in 1936, despite the possibility that its players may no longer be eligible for Olympic hockey. Tommy Lockhart founded the Amateur Hockey Association of the United States (AHAUS) in 1937, after disagreements with the Amateur Athletic Union of the United States over international amateurs. The CAHA and the AHAUS joined to form the International Ice Hockey Association in 1940. Its president W. G. Hardy sought for acceptance by the IOC on terms acceptable to the CAHA. CAHA president George Dudley subsequently threatened to withdraw Canada from the Olympics over the definition of amateur. An IOC decision on the matter was postponed when the 1940 Winter Olympics and 1944 Winter Olympics were cancelled due to World War II. In 1947, the LIHG agreed to a merger with the International Ice Hockey Association, was subsequently renamed to the IIHF, and recognized the AHAUS as the governing body of hockey in the United States instead of the AAU.
