The Sarnia Legionnaires were a Canadian junior ice hockey team that won five Western Jr. 'B' Hockey League championships and four Sutherland Cups as Ontario Hockey Association Junior B champions in the 16 seasons they operated out of Sarnia, Ontario from 1954 until 1970. The club folded after two unsuccessful years as a Tier II Jr. 'A' team. The original Legionnaires were one of the most successful junior teams in Canadian hockey history, playing out of the Western Ontario Junior A and B Hockey Leagues. Counting the Sutherland Cup they won when they were known as the Sarnia Sailors, the franchise won five titles in 20 years, beginning with the 1950-51 campaign. They were founded as members of the Big 10 Junior B Hockey League.
