I have to agree that the 1972 Summit Series victory is the greatest Canadian sporting event in history. This was the first time that Canada put its best players against the Soviet "amateurs." From what I understand many thought it would be a walk in the park for Canada, but it proved to be nothing like that. The cultural impact that this series had transcended sport. Mario Lemieux's goal in 1987 was in perhaps just as dramatic a situation (within the game), but it hasn't had the cultural impact on our country that 1972 did. I suppose, one could make an argument for the 2010 Winter Olympics because Canada hosted it and was quite successful, but I don't see it having the lasting impact in Canadian consciousness as did the 1972 Summit Series.
