The 1981 Labatt Canada Cup was the second best-on-best ice hockey world championship and involved the world's top six hockey nations. Tournament games were held in Edmonton, Winnipeg, Montreal and Ottawa. The Soviet Union defeated Canada in a single game final to win its first title by the score of 8–1. Soviet goaltender Vladislav Tretiak was named most valuable player. Canada's Wayne Gretzky led the tournament in scoring with 12 points.

This second edition of the Canada Cup was originally scheduled to be held in 1979 but was postponed due to disputes between the Canadian Amateur Hockey Association and Hockey Canada. It was postponed a second time in 1980 following the Soviet invasion of Afghanistan and Canada's boycott of sporting events with the Soviet Union as a result. When finally held in 1981, tournament organizer Alan Eagleson speculated it could be the last such event due to rising costs and disappointing attendance. Eagleson generated additional controversy when he refused to allow the Soviets to take the Canada Cup trophy with them to the Soviet Union.

Organization At its congress in the summer of 1978, the International Ice Hockey Federation approved proposals to hold the second and third Canada Cup tournaments in 1979 and 1982. However, tensions between Canada's rival governing bodies, the Canadian Amateur Hockey Association (CAHA) and Hockey Canada, increased after the latter body accused the CAHA of reneging on promises it had made regarding Hockey Canada's control of international events involving professional players. Hockey Canada's chief negotiator for international events, Alan Eagleson, accused the CAHA of attempting to sabotage the Canada Cup and threatened to cancel the tournament if the CAHA refused to compromise with his body.

The tournament was put in further jeopardy in January 1979 when General Motors withdrew as a major sponsor; Eagleson argued GM withdrew as a result of the dispute with the CAHA. The disputes put the two bodies on the verge of severing all ties, a move that would have led to Hockey Canada refusing to release any professional or university player to any of Canada's national teams. The tournament was ultimately postponed by a year until September 1980.

The Soviet invasion of Afghanistan in December 1979 and threatened boycott of the 1980 Summer Olympics in Moscow led organizers to consider again postponing the Canada Cup. While Eagleson initially favoured allowing the tournament to go ahead regardless of the political situation, he ultimately agreed that Hockey Canada should again postpone the Canada Cup after the Canadian Government joined the Olympic boycott. A brief effort to move the tournament to Sweden was quickly put down when Eagleson informed them that neither Hockey Canada nor the National Hockey League Players' Association (NHLPA) would participate in such an event.Pelletier, 2003, p. 53

Undaunted, Eagleson and IIHF president Günther Sabetzki announced that the tournament had again been rescheduled for September 1981. This time, the tournament went ahead as scheduled.

Teams

The Soviet Union treated the 1976 Canada Cup with disdain, but entered this tournament intent on re-asserting themselves following their upset loss to the United States at the 1980 Winter Olympics. They were led by the "KLM Line" of Vladimir Krutov, Igor Larionov, and Sergei Makarov on offence, as well as Viacheslav Fetisov and Alexei Kasatonov on defence, with the venerable Vladislav Tretiak in goal.Pelletier, 2003, p. 56 Featuring a strong mixture of veterans and young players, the Soviets entered the tournament as favourites.

Canada brought a considerably younger team to the 1981 Canada Cup compared to their 1976 entry. Three defencemen – Ray Bourque, Paul Reinhart, and Craig Hartsburg – were under the age of 22, while 20-year-old Wayne Gretzky was expected to be the offensive catalyst.Pelletier, 2003, p. 54 Gretzky's pairing with Guy Lafleur and Gilbert Perreault was highly anticipated (and they would combine with each other on 22% of Team Canada's goals), while the New York Islanders quartet of Mike Bossy, Bryan Trottier, Butch Goring, and Clark Gillies were also expected to be offensive leaders.

With 17 National Hockey League (NHL) players on their roster, Sweden felt confident they could upset the Soviet Union and Canada by utilizing a system of strong team play. Kent Nilsson (coming off a 131-point season for the Calgary Flames), Thomas Steen, Ulf Nilsson, and Börje Salming were expected to be the team's leaders.Pelletier, 2003, p. 58 With only five returning players from 1976 – when they reached the finals – and hurt by the defections of the Šťastný brothers (Peter, Marián and Anton) to Canada, the Czechoslovak team entered the tournament in the midst of a rebuilding phase and were not considered contenders in 1981.

The Americans, riding high following their gold medal victory at the 1980 Olympics, were considered capable of potentially upsetting the stronger teams in the tournament. Mark Howe, Rod Langway, and seven players from the 1980 Olympic team (Bill Baker, Neil Broten, Dave Christian, Steve Christoff, Mark Johnson, Rob McClanahan, and Ken Morrow) were expected to lead the United States.Pelletier, 2003, p. 55 Tony Esposito was the American goaltender for the tournament; he had represented Canada at the 1972 Summit Series, but gained his American citizenship in time to represent his new nation. As in 1976, Finland was expected to finish last in the six-team tournament despite the fact that the Finnish hockey association considered the team sent to Canada among the best their nation had assembled.

Games

Round robin The tournament opened on September 1 at Northlands Coliseum in Edmonton as the Americans defeated a disorganized Swedish team, 3–1. Swedish coach Anders Parmström, upset at how his team underestimated the Americans, sat several of his top players for extended periods of the third period.Pelletier, 2003, p. 60 At the Winnipeg Arena, a young Czechoslovak team battled the Soviet Union to a 1–1 draw in a game marked by rough play. The Soviets were forced to rely on the stellar goaltending of Vladislav Tretiak to preserve the tie. In the third game of the opening day, Canada's "dream line" of Gretzky, Lafleur and Gilbert Perreault combined for ten points as Canada easily defeated Finland 9–0. The second line of Gillies, Trottier and Bossy also combined to score ten points in the game.

Finland fared little better against Czechoslovakia two nights later, dropping a 7–1 result. Finnish goaltender Hannu Lassila was the star of the game, however, as he made several difficult saves to keep the Finns close through two periods. Despite outshooting Finland 26–9, the Czechs managed only a 2–1 lead after 40 minutes before finally overcoming Lassila to score five goals in the third period.Pelletier, 2003, pp. 63–64 Sweden attempted to employ a physical style against the Soviet Union without success, as they surrendered five power play goals in a 6–3 loss.Pelletier, 2003, p. 65 Canada then defeated the United States, 8–3, in a game that was played much closer than the score indicated. The Americans appeared to be headed to a draw with Canada as the two teams were tied at three with nine minutes to play before a power play goal by Mike Bossy sparked a five-goal outburst for the Canadians in the dying minutes of the game.

The Soviets then avenged their 1980 Olympic defeat to the United States with a 4–1 win, while the Swedes defeated Finland 5–0.Pelletier, 2003, p. 68 Ending the third night of play, Czechoslovakia was able to overcome a late two-minute, two-man disadvantage to emerge with a 4–4 tie against Canada in a game that was described as the best of the tournament.Pelletier, 2003, p. 71 Canada then defeated Sweden 4–3, but not before losing Perreault to a broken ankle. Perreault was Canada's leading scorer over the first four games and was considered a contender to be named most valuable player at the time of his injury.Pelletier, 2003, p. 72 The United States then overcame an early two-goal deficit against the Czechs to win 6–2 while the Soviets easily defeated Finland 6–1Pelletier, 2003, pp. 74–75

The final night of round robin play opened with a meaningless game between the United States and Finland. The Americans had already advanced to the playoff round while Finland had been eliminated. The game ended in a 4–4 draw and was most notable for Montreal Forum staff accidentally playing the Italian national anthem instead of the Finnish anthem prior to the start of the game.Pelletier, 2003, p. 77 The Czechs then easily defeated Sweden, 7–1, to advance to the playoff round and eliminate the Swedes.Pelletier, 2003, p. 78 Canada and the Soviet Union closed out the round robin with a battle for first place. A five-goal outburst by Canada in the third period broke a 2–2 tie and sent Canada into the playoffs as the top ranked team. Their 7–3 win was the most lopsided victory Canada had recorded against the Soviets in 20 years.Pelletier, 2003, pp. 79–80

Semi-finals As the top team in the playoff round, Canada faced the fourth place Americans in the first semi-final. Talk entering the game revolved around the defensive style of the United States and whether they could overcome Canada's offensive game and upset the favoured nation in a one-game, winner-take-all scenario. Early play favoured Canada, as they opened the scoring 2:01 into the game on a goal by defenceman Brian Engblom, then extended their lead five minutes later when a long shot by Bossy eluded Esposito in the American goal. Another goal by Bossy saw Canada end the first period with a 3–0 lead. The remaining 40 minutes of the game lacked emotion, and the two teams traded goals for a 4–1 Canadian victory.Pelletier, 2003, p. 83

The second place Soviet Union faced third ranked Czechoslovakia in the second semi-final. Soviet coach Viktor Tikhonov was agitated following his nation's 7–3 defeat to Canada to end the round robin, while the Czechs had grown increasingly confident of their ability as the tournament progressed. It was the Soviets, however, who scored three first period goals to take an early 3–0 lead. The young Czechoslovak team pressured their opponents for much of the final 40 minutes, outshooting the Soviets 23–11 in the second and third periods combined. Tretiak withstood the pressure in the Soviet goal, however, allowing only one goal as the Soviet Union emerged with a 4–1 victory.Pelletier, 2003, pp. 81–82

Final Canada entered the final facing pressure to defeat the Soviets. The Soviet national team's easy victory over the National Hockey League's all-stars in the 1979 Challenge Cup left the Canadians searching to regain command of their rivalry with the Soviets. Coach Scotty Bowman called it a "must win game" for Canada: "We really are favorites in the final. Nobody in this country will tolerate a loss." The players also spoke of their desire to show the Soviets that they were the world's top hockey nation. But also the Soviet Union was under pressure, as their most desirable trophy, the Olympic gold medal, had been denied them by the United States Amateur team, during the 1980 Winter Olympics at Lake Placid. During their pre-game preparations, Tikhonov called upon his team to play the finest games of their lives: "Today you got to play so well that the entire Canadian population will talk about you afterwards and remember you for a long time. Play so well that the Canadian fans when they will leave Forum will wait for you when you get on the bus after the game and admire you."Pelletier, 2003, p. 84
