Ottawa clinched a playoff berth in week 17 with a victory over the Winnipeg Blue Bombers on October 16, 2015.

On November 22, 2015, the Redblacks defeated the Hamilton Tiger-Cats 35–28 in the Eastern Final to advance to their first Grey Cup game, which they lost 26–20 to the Edmonton Eskimos.

On January 15, 2015, the Redblacks traded Jasper Simmons and Dan Buckner to the Calgary Stampeders in exchange for Maurice Price.

Ottawa is hoping that Price can provide the offense with some explosiveness which the team lacked during its inaugural season.
