He started his musical career as an orchestral clarinetist with the Turku Philharmonic (1971–76). He then became the principal clarinet of the Helsinki Philharmonic from 1977 to 1982. During this time, he started to study conducting with Jorma Panula at the Sibelius Academy, where his classmates included Esa-Pekka Salonen and Jukka-Pekka Saraste. In 1982, he won the Besançon Young Conductor's Competition.
Vänskä became principal guest conductor of the Lahti Symphony Orchestra in 1985, and chief conductor in 1988. He concluded his tenure with the Lahti Symphony Orchestra in 2008 and is now the orchestra's Conductor Laureate. His complete set of Sibelius symphonies with the Lahti Symphony Orchestra, also on the BIS label, has garnered widespread acclaim. He has recorded extensively with the Lahti orchestra for the BIS label, including music of Kalevi Aho, Einojuhani Rautavaara, Bernhard Crusell, Uuno Klami, Tauno Marttinen, Robert Kajanus, Sofia Gubaidulina, Joonas Kokkonen, Jan Sandström, Jean Sibelius, and Fredrik Pacius.
Vänskä was chief conductor of the Iceland Symphony Orchestra from 1993–1996. In 1996, he was appointed chief conductor of the BBC Scottish Symphony Orchestra (BBCSSO), and served in that capacity until 2002. With the BBCSSO, he made recordings of the complete Carl Nielsen symphonies for the BIS label. In June 2014, the Iceland Symphony Orchestra announced the return of Vänskä to the orchestra as its next principal guest conductor, effective with the 2014-2015 season.
In 2003, Vänskä became the music director of the Minnesota Orchestra. He and the orchestra have received critical praise, and he is generally regarded as having enhanced the quality of the orchestra. In 2004, Vänskä and the Minnesota Orchestra began a five-year project to record the complete Beethoven symphonies on the BIS label. In 2005, Vänskä signed a contract extension with the Minnesota Orchestra through at least 2011. In September 2009, the orchestra announced the extension of Vänskä's contract through the 2014–2015 season. He announced his resignation on October 1, 2013, one year after management locked out the musicians in a longstanding labor dispute. In January 2014 Vänskä and the Minnesota Orchestra won a Grammy for best orchestral performance for the album of Sibelius' Symphonies Nos. 1 and 4. He was re-appointed music director of the Minnesota Orchestra in April 2014 with a two-year contract.
In May 2008, an orchestral piece composed by Vänskä titled "The Bridge" was premiered by the Metropolitan Symphony Orchestra, led by William Schrickel, assistant-principal bassist of the Minnesota Orchestra. Vänskä himself attended the world premiere.
Vänskä and his former wife Pirkko, a freelance drama critic, have three grown children, one of whom, Olli, plays violin in the Finnish folk metal band Turisas. The couple separated in 2009. In December, 2014, Vanska announced via Facebook that he and Erin Keefe, the Minnesota Orchestra concertmaster, had become engaged. He maintains a residence in Minneapolis. In private life, one of his hobbies is riding motorcycles.
