Adams Division Finals
The Quebec Nordiques and Montreal Canadiens battled in a seven-game series. Bitter rivals from the province of Quebec, the Nords shocked the Habs in 1982, only to see a fourth-place Montréal club upset Québec the year before. In the deciding Game 7 at the Montreal Forum, Peter Šťastný scored the game and series winning goal, giving Québec an improbable 3–2 overtime win and berth in the Wales Conference Finals.
