Playing career
Following the 2016–17 season, after recording a career-best 44 points in 59 games after his first season with HC Vityaz in the Kontinental Hockey League, he signed an entry-level contract with the Toronto Maple Leafs on 17 March 2017.
Despite a strong push for a roster spot as the Leafs' fourth-line center, he was assigned to the Maple Leafs American Hockey League affiliate, the Toronto Marlies for the 2017–18 season. In adapting to his first North American season, Aaltonen established himself among the offensive leaders with the Marlies, contributing 20 goals and 43 points in 64 regular season games. Unable to earn a call-up to the NHL, Aaltonen continued in the post-season with the Marlies, helping claim the club's first Calder Cup in posting 13 points in 20 games.
As an impending restricted free agent from the Maple Leafs but unable to make his NHL debut, Aaltonen opted to return to the KHL on a contract with former Russian club, Vityaz on 1 July 2018.
Following his first full season with SKA Saint Petersburg in 2020–21, Aaltonen was returned in trade, alongside Viktor Antipin, to former club HC Vityaz in exchange for four prospects on 15 June 2021.
On 1 May 2022, Aaltonen left Vityaz as a free agent and was announced to have signed a two-year contract to remain in the KHL with Avtomobilist Yekaterinburg. Having signed before the Russian invasion of Ukraine, Aaltonen sought a release from his contract with Avtomobilist and on 21 June 2022, was signed to a two-year contract with Swiss club, EHC Kloten of the NL.
