The 1927 Macdonald Brier Tankard, the Canadian men's national curling championship, was held March 1–3 at the Granite Club in Toronto.

The event began with an opening banquet with Ontario Lieutenant Governor William Donald Ross and Ontario Premier Howard Ferguson welcoming players.

[2] After successful trips by the winner of the Manitoba Bonspiel in 1925 and their participation in the Quebec Bonspiel being deemed popular enough to consider a national tournament in 1926, the Stewart brothers of Macdonald Tobacco would sponsor what would become the Brier in 1927.

Played at the Granite Club in Toronto, the tournament would feature teams from four provinces, two cities, and a representative from Western Canada and Northern Ontario, the latter becoming a fixture at the Brier.

It would be the only Brier that would have all games go 14 ends (with two games going to a 15th end to break ties)[3] The teams are listed as follows:[4] Skip: Peter Lyall Third: Willie Brown Second: Howard Stewart Lead: Bruce Stewart Skip: Johnny Malcolm Third: Fred Beatteay Second: Reg Shives Lead: Elbridge MacKay Skip: Emmett Smith Third: Dunc Sutherland Second: Dan Millar Lead: Mel Hunt Skip: Murray MacNeill Third: Al MacInnes Second: Cliff Torey Lead: Jim Donahoe Skip: Robert MacKenzie Third: Bill Watson[6] Second: Mel Hunt[6] Lead: Harry Watson Skip: Major Robert Whyte Third: Robert Morton Second: Malcolm Holliday Lead: Joe Power Skip: Oswald Barkwell Third: Alf Hill Second: Hector Hay Lead: Pete Wilken Skip: William Scott Third: Ed Peaker Second: Thomas Wright Lead: Fred Lucas Tuesday, March 1 (Morning)[9][10] Tuesday, March 1 (afternoon)[11] Wednesday, March 2 (morning)[12][13] Wednesday, March 2 (afternoon)[14] Wednesday, March 2 (evening)[15] Thursday, March 3 (morning) Thursday, March 3 (afternoon)[16][17] Teams were chosen by invitation.
