The 1973 Macdonald Brier, Canada's national men's curling championship was held March 5–11 at the in Edmonton. The event was memorable for having particularly bad ice conditions, considered by some as the "worst (Brier ice) ever manufactured". There was a great thickness of frost on the ice, which was also dotted by tiny pools of water. Team Saskatchewan, skipped by Harvey Mazinke proved to be best adapted at playing under these conditions, winning the event after posting a 9-1 record, despite not being considered the favourites. Team Ontario (Paul Savage) and Team Nova Scotia tied for second with a 6-4 record, the lowest ever record for a second place team.
