1931 Macdonald Brier
The 1931 Macdonald Brier, the Canadian men's national curling championship, was held from March 3 to 5, 1931 at the Granite Club in Toronto, Ontario.
Team Manitoba, skipped by Bob Gourley, captured the Brier Tankard with a round robin record of 8-1. This was Manitoba's fourth consecutive Brier championship. A tiebreaker game was played to determine the runner-up as both Ontario and Toronto finished the round robin with 6-3 records. Ontario defeated Toronto in an extra end 13-12 to finish runner-up.
This was the last Brier to feature Montreal and Toronto as their own teams.
The 1931 Brier was one of only two Briers to feature no ends that were blanked. This Brier also set the record at the time for the most extra ends played in a single Brier with six.
