Lumsden had a standout career at McMaster where he won the Hec Crighton Trophy in 2004 and was invited to the East-West Shrine Game.

In 2009, Lumsden signed with the Edmonton Eskimos, but he sustained a season-ending shoulder injury in their opening game.

He signed with the Calgary Stampeders on a practice roster agreement midway through the 2010 season, and was activated in October.

It was expected that he participated in both the two-man and four-man teams in the 2009–10 world competitions leading up to the 2010 Winter Olympics.

Lumsden became partners with Lyndon Rush at the beginning of the 2012 season and the duo won their first World Cup Gold medal together in the two-man event on February 3, 2012.
