Otto Leskinen

In June 2018, Leskinen was invited to attend the Montreal Canadiens of the National Hockey League (NHL) training camp. In December 2018, Leskinen helped lead Kalpa to their first Spengler Cup Championship. He recorded one point during the tournament, an assist off captain Tommi Jokinen's goal in the semi-finals.

Leskinen had a break out season in the final year of his contract. He recorded a career-high 31 points, 23 assists, and 8 goals in 57 games during the 2018–19 season. As a result, Leskinen signed a two-year, entry-level contract with the Montreal Canadiens in May 2019. He was invited to their annual development camp in June that year and competed in their pre-season games.

Leskinen was selected to try out for Team Finland ahead of the 2017 World Junior Ice Hockey Championships, but failed to make the final cut. In February 2019, Leskinen was selected to compete for Team Finland in the Euro Hockey Tour. He was later invited to tryout for Team Finland's World Championship team.

Leading up to the 2015 NHL Entry Draft, Leskinen was ranked 114th over all International Skaters by the NHL Central Scouting Bureau. While he went undrafted in North America, Leskinen signed a three-year contract extension with KalPa on 29 April 2015. He signed a two-year extension with KalPa on 21 November 2017.

Leskinen competed with the U18 Team Finland squad at the 2015 IIHF World U18 Championships, where he won a silver medal.
