Document 11: Ottawa Rough Riders: The Ottawa Rough Riders were a Canadian Football League team based in Ottawa, Ontario, founded in 1876.

Document 13: Canadian football: Canadian football has mostly been confined to Canada, with the United States being the only other country to have hosted a high-level Canadian football game. The CFL's controversial "South Division" as it would come to be officially known attempted to put CFL teams in the United States playing under Canadian rules between 1992 and 1995. The move was aborted after three years; the Baltimore Stallions were the most successful of the numerous Americans teams to play in the CFL, winning the 83rd Grey Cup. Continuing financial losses, a lack of proper Canadian football venues, a pervasive belief that the American teams were simply pawns to provide the struggling Canadian teams with expansion fee revenue, and the return of the NFL to Baltimore prompted the end of Canadian football on the American side of the border.
