Curling Canada introduced a new 16-team format for both the Brier and Tournament of Hearts for 2018, under which all 14 member associations of Curling Canada are now represented in the main field, rather than being limited by a pre-qualifying tournament. The teams were divided into two pools for round robin play, after which the top four teams from each advanced to a Championship Pool. Alongside the inclusion of the previous year's champions as Team Canada, the final spot in the tournament was filled by a wildcardplay-in game held on the Friday before the tournament. The rinks of John Epping, Mike Fournier, and Greg Smith made their Brier debuts. Team Canada's Brad Gushue set a new record for the most Canadian national men's championship game wins as a skip when he skipped the 114th victory of his Brier career over the Northwest Territories on March 5.
;Notes
British Columbia's alternate Brad Wood threw lead stones after the fourth end during Draw 2, because lead David Harper abruptly left the tournament to join his wife for the birth of their second child. Wood continued to throw lead stones for the rest of the Brier except for Draw 10; Harper returned to throw lead stones against Newfoundland and Labrador before leaving once again. Before Team BC's placement round match, third Jeff Richard left to join his wife for the birth of their child; in their game against New Brunswick, second Andrew Nerpin threw third stones, while alternate Brad Wood and Nerpin split the throwing of second stones.
Northern Ontario's alternate Tanner Horgan threw lead stones during Draws 9, 19 & 20; lead Ryan Harnden was hospitalized with an illness for a day during Draws 19 and 20.
During Draw 9, Quebec's alternate Émile Asselin threw lead stones for the last 3 ends.
During Draw 8, Yukon's Wade Scoffin threw second stones for six ends; lead Steve Fecteau threw second stones for three ends, while alternate Clint Ireland threw lead stones for three ends.
Each team that finished fifth through eight in their pool played the team that finished in the same position in the opposite pool for the purpose of determining final tournament ranking. For example, the winner of the game between fifth place teams was ranked ninth place overall, the loser of that game was ranked tenth place, and so on.
