He played in both of Montreal's Grey Cup victories in 2009 and 2010. In 2011, he recorded a career-high in receiving yards with 675 yards to go along with five touchdowns, including the 20th scored of his career that year. At the end of the 2012 Eastern Final against the Toronto Argonauts, Bratton missed an attempt to catch a deflected ball which would have been the game-tying touchdown with only 39 seconds left on third town. The Alouettes lost possession of the football and the Argonauts went on to win the 100th Grey Cup. Two weeks before entering free agency, Bratton was released on February 1, 2013 so that he could pursue offers from other teams.
