In 1985 -- 86, the Flames became the first Calgary team since the 1923 -- 24 Tigers to compete for the Stanley Cup. In 1988 -- 89, the Flames won their first and only championship.

Document 4: Stanley Blair: Coming out of the Southeastern Oklahoma State University football program, Blair joined the Edmonton Eskimos in 1987 and took the CFL by storm, capturing the Jackie Parker Trophy as best rookie in the West and winning a Grey Cup. His blocked kick in the 75th Grey Cup classic was instrumental. He played two more seasons in Edmonton and was selected as an all-star in each. He was courted by many National Football League teams, but signed with the Phoenix Cardinals and played only 5 games with them before injuries ended his career.
Document 5: Winnipeg Blue Bombers: The Blue Bombers were founded in 1930 as the Winnipeg Football Club, which remains the organization's legal name today. Since that time, they have won the league's Grey Cup championship 10 times, most recently in 1990. With 10 wins, they have the third - highest win total in the Grey Cup among active and defunct CFL teams. Though they are currently the team with the longest Grey Cup drought (and in the West Division overall (although their 1990 win, their most recent, came when they played in the East Division)), no other CFL franchise has as many Grey Cup appearances as the Blue Bombers' current 25. The Blue Bombers were the first team not located in Ontario or Quebec to win a championship.
Document 6: Edmonton Eskimos: The Edmonton Eskimos are a professional Canadian football team based in Edmonton, Alberta, competing in the West Division of the Canadian Football League (CFL).

The Eskimos were founded in 1949, although there were clubs with the name Edmonton Eskimos as early as 1895. The Eskimos are arguably the most successful CFL franchise of the modern era (since 1954), having won the league's Grey Cup championship fourteen times, second overall only to the Toronto Argonauts who have won seventeen. This includes a three-peat between 1954 and 1956 and an unmatched five consecutive wins between 1978 and 1982, and most recently in 2015.
Document 7: Shalon Baker: He went to Canada, playing with the Edmonton Eskimos. In his first season, 1995, he had 79 catches gaining 1,156 yards and 5 touchdowns, and won the CFL's Most Outstanding Rookie Award.

Document 8: Ottawa Rough Riders: The Ottawa Rough Riders were a Canadian Football League team based in Ottawa, Ontario, founded in 1876. Formerly one of the oldest and longest lived professional sports teams in North America, the Rough Riders won the Grey Cup championship nine times. Their most dominant era was the 1960s and 1970s, a period in which they won five Grey Cups. The team's fortunes waned in the 1980s and 1990s and they ultimately ceased operations following the 1996 season. Five years later, a new CFL team known as the Ottawa Renegades was founded, though they suspended operations in 2006. The Ottawa Redblacks, who own the Rough Riders intellectual properties, joined the league in 2014.

Document 12: Toronto Argonauts: The Toronto Argonauts (officially the Toronto Argonaut Football Club, commonly referred to as the Argos) are a professional Canadian football team competing in the East Division of the Canadian Football League (CFL). Based in Toronto, Ontario, the team was founded in 1873, and is the oldest existing professional sports team in North America still using its original name, and they are the oldest-surviving team in both the modern-day CFL and East Division. The team's origins date back to a modified version of rugby football that emerged in North America in the latter half of the nineteenth century.

Document 15: 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.
