Born in Winnipeg, Manitoba on January 31, 1914 Alex Singbush paid his dues in Senior hockey and the American Hockey League before he got his NHL chance in 1940. Singbush, a defenseman played for three years in Sudbury the joined the AHL in 1937 where he spent the next three seasons, primarily with New Haven before he got the call from the Montreal Canadiens.
Montreal, with their roster thinned out during wartime summoned Singbush to play 32 games on their blueline. He managed five assists and played three more games in the playoffs, but didn't register a point. After playing one season for Montreal the Canadiens traded his rights to the Washington Lions of the AHL in October of 1941.
Singbush played the next two years in the AHL, then two more seasons of Senior hockey before returning to the American League for just one game with the Providence Reds during the 1945-46 campaign. Singbush suited up for five contests with the Hull Volants of the Quebec Senior loop that year as well. They were the last games of his career.
