He started ski jumping at the age of eight . In 1994 he moved to Kuopio in eastern Finland because of the better training conditions and started there for the club in that city, the Puijon Hiihtoseura .
In 1996 he competed in his first World Cup competition in Lillehammer, Norway, and immediately scored World Cup points. In his career he was able to achieve two individual World Cup victories (1999 in Kuopio , 2001 in Willingen ), as well as two second and third places; He won twice with the Finnish team (Willingen 2001, Lahti 2000). Kantee was nominated three times for a Nordic World Ski Championships: 1997 in Trondheim ( Norway ), 1999 in Ramsau ( Austria ) and 2001 in Lahti ( Finland ). The first time, however, it was not used. In Ramsau he did not succeed in winning a medal, in the individual he reached 13th place (normal hill) and 30th place (large hill). In the team competition on the large hill, the Finnish team landed on 4th place. Two years later he improved on the normal hill in Lahti to 10th place, on the large hill he finished ninth one place ahead. In team jumping, he won silver with the Finnish team on the normal as well as on the large hill.
All through his career he had painful back problems. In 2004, after the third swelling of the spinal discs, this forced him to retire at the age of just 25.
From the 2006/07 winter season, Kantee worked as a ski technician for the Finnish national ski jumping team and was also the ski jumping trainer for the youngsters in Kuopio from 2007 to 2009 . He came closer to his goal of becoming a coach when, after moving to Lahti in summer 2009, he began to support the training of ski jumpers at the base there. After he was allowed to take on more and more of the tasks of a coach in the national team, he was finally nominated in spring 2010 as assistant coach of Pekka Niemelä , the new coach of the Finnish national ski jumping team.
