24 teams
Of current CFL teams, Saskatchewan Roughriders have 4 Wins - 1966,1989,2007, and 2013 The above is only the answer to the question if one restricts the question to current CFL teams. The CFL teams that were in the USA, with the exception of Baltimore, collectively had zero Grey Cup wins. But the question was wide open. The correct answer would be that dozens of teams have no Grey Cup wins. One must remember that the Ontario Rugby Football Union (ORFU) regularly challenged for the Grey Cup right up until the mid-1950s. Only three ORFU teams ever won the Grey Cup. The Sarnia Imperials and Toronto Balmy Beach each had two victories, and the Hamilton Wildcats one. But there were several teams in the ORFU from time to time, none of which ever won (or even played in) a Grey Cup game. There were also a number of eligible teams out west that never made it to the big game. Likewise, going back to the days when the university teams could challenge, only University of Toronto (4 wins) and Queens University (3 wins) ever played in a Grey Cup game. The rest never got on the field. The true number of teams that were eligible to challenge but never made it, and therefore won zero Grey Cup games, might never be known. And, of course, teams which never played Canadian Football have never won it either.
If the question is, "How many times did the same two teams appear in the Grey Cup two years in a row?" the answer is, lots. In some cases the same teams were in the Grey Cup for three years running, which I would count as two rematches, that is, two games where the teams were the same teams as the year before. So, how many times has the Grey Cup been between the same two teams who were in it the year before? Over 101 Grey Cup games, 16 times, most recently in 2009-2010.
As of 2013, all eight CFL teams have at least one Grey Cup victory to their credit. As of 2014 there are nine teams: the new Ottawa Redblacks have no Grey Cup wins unless you count the wins by the Ottawa Rough Riders.
The 2012 Grey Cup was played in the Rogers Centre, Toronto.
The game in 2012 was the 100th Grey Cup game.
All the teams which have won the Grey Cup, with only one exception, have been Canadian teams, which is to say that they were based in Canadian cities, including the most recent team to win it.
The Grey Cup Game is not hosted by a team, it is hosted by a city. Until 1954, the Grey Cup Game was almost always played in Toronto, because the largest stadium in Canada at the time (Varsity Stadium) was located in Toronto. From the time the Grey Cup was donated by the Governor General (1909) until 1952, Toronto-based teams had won the Grey Cup Game (played in Toronto) 17 times. Since the Canadian Football League (CFL) was established in 1958, the Grey Cup has been the exclusive property of the CFL. The following CFL teams have played in a Grey Cup Game held in the team's city: 1963 B.C. Lions (Vancouver) (loss) 1972 Hamilton Tiger-Cats (win) 1977 Montreal Alouettes (win) 1979 Montreal Alouettes (loss) 1982 Toronto Argonauts (loss) 1983 B.C. Lions (Vancouver) (loss) 1994 B.C. Lions (Vancouver) (win) 2002 Edmonton Eskimos (loss) 2012 Toronto Argonauts (win) As you can see, playing on home ground does not seem to improve nor hurt the chances of winning the Grey Cup.
