Pekka Rautakallio started his ice hockey career in local club of his hometown, Ässät in 1970. He also represented the club's football team. As a skilled and mobile defenceman, Rautakallio was soon noticed and he played on his first International tournament in 1972. Rautakallio gained the attention of World Hockey Association officials when the 1974 Summit Series team played an exhibition against the Finnish national team. The Phoenix Roadrunners thought to sign him to a contract that year, but hesitated out of fear that the challenge of a Finn adapting to life in Arizona on his own would be too great. They brought him over one year later, along with his countryman Lauri Mononen, and signed both to two-year contracts. Rautakallio recorded 50 points, including 11 goals, in 1975–76. He finished as the leading scorer among rookie defencemen, and fifth overall for all defencemen. He then fell to 35 points in 1976–77. The Roadrunners ceased operations following the season, and lacking other options in North America, Rautakallio returned to Finland. Rautakallio returned to Ässät, which had joined the recently formed SM-liiga, and established himself as a top defenceman in the league. He was named defenceman of the year in both 1977–78 and 1978–79; the SM-liiga ultimately named the award the Pekka Rautakallio trophy in his honour. He recorded 37 points in 36 games in 1977–78, then improved to 25 goals and 53 points the following year. Ässät established its place as the SM-liiga's dominant team by winning the Kanada-malja as league champions in 1978 and reaching the final in 1979. The Atlanta Flames brought Rautakallio back to North America in 1979 as general manager Cliff Fletcher signed him to a National Hockey League contract. The Flames were impressed with the power of his shot and his speed; he finished his first NHL season with 30 points. Rautakallio relocated with the franchise when it moved to Canada and became the Calgary Flames in 1980–81. He led the team in scoring by a defenceman with 56 points. The 1981–82 season was Rautakallio's best in the NHL. He again led the team's defencemen in scoring, and was fourth overall, with 68 points in 80 games. He played for the Campbell Conference team at the 1982 All-Star Game, and in doing so became the first Finn in NHL history to appear in the mid-season contest. However, he opted to return to Finland after the season as his sons were beginning school. He feared they were becoming too Canadian and wanted them to grow up in his homeland. Rautakallio returned to play for HIFK, instead of Ässät, and served for a while as the captain of HIFK. Rautakallio retired from playing in 1989 after two seasons with SC Rapperswil-Jona in Switzerland.
Coaching career
Rautakallio remained with SC Rapperswil-Jona and joined the team as its coach. He later coached in Bern and Zurich. Returning to Finland, Rautakallio twice served in Espoo as head coach of Blues. His first term came during the 1998–99 SM-liiga season, when he was replaced mid-season by Hannu Saintula. Rautakallio's second term came when he was the replacement for Hannu Virta, who was sacked during the 2004–05 SM-liiga season. Most recently, he served as head coach of Dynamo Riga in the Kontinental Hockey League. Rautakallion joined the squad in 2011, but was dismissed midway through the 2012–13 season as Riga struggled.
