1970 Macdonald Brier

The hometown Don Duguid rink out of Winnipeg's Granite Club won the event in the last draw, when they beat Saskatchewan's Bob Pickering rink in front of 9,287 fans at the Winnipeg Arena, which was "filled to capacity".

Duguid's only loss came against team British Columbia, skipped by 1964 Brier champion Lyall Dagg, who would go on to finish in third place.

Manitoba's first round match against Alberta, skipped by 1961 Brier and World Champion Hec Gervais proved to be the deciding game.
