The 2011 BDO Canadian Open of Curling was held from January 26–30 at the General Motors Centre in Oshawa, Ontario.

The competition was marked by an interesting turn of events when the Thomas Ulsrud rink failed to win a game against Peter Corner.

Team Ulsrud's loss created an eight-way tie in 2–3 win–loss records, prompting a draw shot challenge and the scheduling of two tiebreakers.

This marks the first time in Grand Slam history that a 2–3 win–loss record could qualify a team to a tiebreaker.

Mike McEwen won his second Grand Slam of the season in an extra-end win over Glenn Howard in the final.
