The win kept the second-place Tiger-Cats (7-9-0) in the hunt for the East Division title while also securing them a playoff spot. They now trail the Redblacks (7-8-1) by just a single point with two weeks to play in the regular season.
The Redblacks turned the ball over on their second possession of overtime after quarterback Henry Burris was stripped while being sacked.
Maher had an 18-yard field goal on the first possession of overtime to give the Tiger-Cats a 36-33 lead but Chris Milo connected from 45-yards out to tie the game 36-36.
At 2:42 of the fourth quarter, a 10-yard touchdown pass from Jeremiah Masoli to John Chiles, once converted, pulled the Tiger-Cats to within a single point of the Redblacks. Burris responded with a four-yard touchdown pass to Ernest Jackson, but the extra point was wide and the lead was seven at 33-26.
Hamilton tied the game tied the game when CJ Gable completed a five-yard catch-and-run touchdown from Masoli with less than five minutes to play.
