Kantoyeu made his official debut at the 2000 Summer Olympics in Sydney, where he competed in the men"s bantamweight category (54 kg). He pinned Cuba"s Wilfredo García on his opening bout, but could not beat Kyrgyzstan"s Nurbin Donbaev with a score 2–5 in the prelim pool. Despite a single loss, Kantoyeu still managed to secure a spot for the quarterfinals because of the most number of points collected from the elimination round.
Determined to return again to the wrestling scene, Kantoyeu greatly emerged as a top medal contender at the 2001 World Wrestling Championships in Sofia, Bulgaria, where he beat Iran"s Babak Nourzad to take home the gold medal in the men"s bantamweight category.
In 2002, Kantoyeu took a year off from the tournament because of sustained injuries, but sought his official return at the 2003 World Wrestling Championships in New York City, New York, United States, where he reaped an astonishing defeat from Japan"s Chikara Tanabe in his opening match. At the 2004 Summer Olympics in Athens, Kantoyeu qualified for his second Belarusian squad, as a 33-year-old, in the men"s featherweight class (55 kg) by receiving a berth and placing second behind Cuba"s René Montero from the Olympic Qualification Tournament in Novi Sad, Serbia and Montenegro.
He lost his opening bout to Ukrainian wrestler and 2003 world bronze medalist Oleksandr Zakharuk, but scored a single triumph to subdue Kazakhstan"s Baurzhan Orazgaliyev in the prelim pool. Finishing second in the elimination round and fifteenth overall, Kantoyeu could not deliver a remarkable attempt from Sydney to put him further into the quarterfinals.
Kantoyeu was also a member of the Belarusian national wrestling team since the breakup of the Soviet Union, under his personal coach Valentin Murzinkov.
