Canada beat Brad Gushue of Newfoundland and Labrador 8-6 in Saturday's semifinal at Scotiabank Saddledome.
It was the seventh win for Canada since Morris demoted himself to third and handed skipping duties off to Pat Simmons midway through the preliminary round.
The Glencoe Club rink from Calgary claimed the fourth and final playoff berth with a 7-4 record in the round robin.
Canada edged Saskatchewan's Steve Laycock 8-7 in an extra end in Saturday's earlier playoff game between the third and fourth seeds.
Jacobs topped the preliminary round with a 10-1 record. His Sault Ste. Marie team won a Canadian title two years ago and Olympic gold last year.
Sunday's winner represents Canada at the world men's curling championship in Halifax later this month.
Gushue will face Saskatchewan for the bronze medal Sunday.
