Kerr started his career in his hometown of
Brockville,
Ontario, playing junior and intermediate amateur hockey for Brockville of the
Ontario Hockey Association. He turned professional in
Pittsburgh,
Pennsylvania in 1907–08. Kerr started 1908–09 with Pittsburgh, but left after seven games to join the Toronto team of the
Ontario Professional Hockey League. After three games in Toronto, Kerr jumped to the
Ottawa Senators and became a star. . Ottawa was rebuilding after the "Silver Seven" years and was seeking a player on left wing. Executive Weldy Bate had read that Kerr had scored five goals in a game for Toronto. Bate sent coach Pete Green who confirmed Kerr's ability and an offer was made to Kerr, who then moved to Ottawa. He played with future
Hall of Famers Marty Walsh and
Billy Gilmour. He also played alongside
Bruce Ridpath and scored 20 goals in nine games as Ottawa won the
Eastern Canada Hockey Association title and the
Stanley Cup. In 1910, Kerr suffered a serious skate cut to his right eye, at first losing his sight, necessitating an eye operation, limiting his play to five games. He would recover to play in the
1910–11 season. During the 1910–11 season, he along with Walsh and Ridpath, scored in twelve consecutive games, including five in one game and had 32 goals in 16 games to finish behind Walsh in
NHA scoring. Kerr, Ridpath and Walsh had one, two and three goals respectively in a 7–4 Stanley Cup challenge win over
Galt, Ontario. Kerr retired after the 1911–12 season but
Lester Patrick lured him to
Victoria,
British Columbia of the
Pacific Coast Hockey Association in 1913–14. He played three seasons with Victoria Aristocrats and moved with the club to Spokane for the 1916–17 season when the Victoria arena was taken over for wartime activities. Kerr served during World War I from 1917 to 1919, but returned to ice hockey to play another season with Victoria, retiring in 1920. ==Personal life==
