Lorne Carr's career started out with the New York Rangers. NHL records indicate that he played in 14 games with the Rangers in 1933-34, even though Carr hardly played during any of those 14 games.
Carr moved across the city the next year to play for the New York Americans. It was with the Americans that Carr established himself as a bonafide NHL player. Lorne recorded 31 points in 48 games in his first real season in the NHL. He ended up playing seven seasons with the Americans, recording more than 25 points on five occasions, before he was traded to the Maple Leafs after the 1940-41 campaign.
Lorne became a league star in Toronto. In 1942-43 he exploded for 60 points in 50 games and in 1943-44 Lorne finished third in the NHL with 36 goals, 38 assists and 74 points. He was an NHL First Team All-Star in both 1943 and 1944. Lorne was also a solid playoff performer, helping the "Buds" won the Cup in both 1942 (playing on a line with Billy Taylor and Sweeney Schriner) and 1945 (Gus Bodnar replaced the departed Taylor by this time).
Carr retired after the 1945-46 campaign. Carr left the NHL with career totals of 204 goals, 222 assists and 426 points in 580 regular season games while adding 19 points in 53 playoff contests.
In retirement Carr moved to Calgary and opened the Amylorne Motel, which featured an 18 hole golf course and driving range. He also opened a pool hall with former teammate Fred Hergerts.
