The 2005 season was more successful for Glenn. Despite missing three games due to injury, Glenn had his best season as a Bomber. He completed 231 of 403 pass attempts (57.3%) for 3,571 yards and 27 touchdowns. His 27 TD passes was third best in the CFL. He also rushed for one touchdown on October 10 versus the B.C. Lions. That October 10 game at Canad Inns Stadium was arguably Glenn's best single-game performance of his CFL career. He passed for 410 yards and five touchdowns, including four TD completions to slotback Milt Stegall. Glenn would go on to surpass the 300-yard passing mark on five occasions in 2005. Despite impressive numbers from Glenn, the Bombers finished 5-13.
