Joseph then headed to Canada to try his luck at finally playing quarterback as a professional. He was acquired as a free agent by the Ottawa Renegades in 2003 and during that season unseated incumbent Dan Crowley for the starting job. In the last game of the 2005 season, a victory over the division-leading Toronto Argonauts, Joseph became only the third (after Damon Allen and Tracy Ham) quarterback in Canadian Football League history to garner over 1000 rushing yards in a single season, finishing with 1006.
