Wood was born in Scotland but raised in Saskatchewan. He joined the Regina Pats in 1928-29, just one year after the franchise won the Memorial Cup. He would only play one season in Regina/ Tje Calgary Canadians ended Regina's run that spring.
Wood would sign with the Chicago Black Hawks organization, though he would never play with the Hawks. He would be assigned to the minor leagues where he would extensively travel over a 13 year career (plus two more seasons of senior hockey). He found great success, too, as an all star and shutout king.
On January 31st, 1937 Alex Wood got his only chance in the National Hockey League. The New York Americans were in need of a goalie for their game against the visiting Montreal Maroons. Their regular goalie, Alfie Moore, was unable to play that night. They summoned Wood from the New Haven Eagles to travel to New York and play in the game.
Wood played very well, but ultimately lost the game 3-2 in overtime. Note that he is credited with playing 70 minutes in his only game. Back in those days over time was a full 10 minutes and not sudden death.
