After the Olympic Games in Seoul in 1988, manager Enrico Dionisi brought Surin to Siena and he was trained by the Italian coach Franco Barucci. Barucci persuaded Surin away from his favoured long jump event, in favour of the 100 m. Barucci predicted he could run 10.10 seconds for the event. Surin won the following Canadian championships in 10.14 seconds.
At the 1990 Commonwealth Games, Surin won a bronze medal in 100 m and was seventh in the long jump. At the 1991 World Championships, Surin was eighth in the 100 m, and at the 1992 Summer Olympics he was 4th in the 100m and reached the semifinals as a member of Canadian 4 × 100 m relay team.
At the 1993 World Championships, Surin was fifth in 100 m and won a bronze medal as a member of Canadian 4 × 100 m relay team. At the 1994 Commonwealth Games, Surin won the gold medal in 4 × 100 m relay and was eliminated in the semifinal of 100 m. Competing for the province of Quebec, Surin edged out Donovan Bailey to win gold in the 100 m at the 1994 Francophone Games in Paris with a games record time of 10.08 seconds. At the 1995 World Championships, Surin won a silver medal in 100 m, behind compatriot Bailey, and a gold medal as a member of Canadian 4 × 100 m relay team.
At the AtlantaOlympics, the Canadian relay team were not favoured, although they had won almost all of the titles available during the previous two years, but they had done it in absence of the United States team. However, in the 4 × 100 m relay final, the Canadian team beat United States by almost half a second, establishing itself the best relay team in the world. Surin also reached the semifinal of 100 m in the same competition.
Surin and the Canadian team won a gold medal again at the 1997 World Championships and a silver medal at the 1998 Goodwill Games. He was also seventh in 100 m at the 1997 World Championships and won a silver medal in 100 m at the 1999 World Championships. His time matched Donovan Bailey's Canadian record of 9.84. At the time, this was the fastest losing time in a 100 m race.
At the 2000 Summer Olympics, Surin, one of the gold medal favorites, had not fully recovered from a leg injury sustained at the Canadian championships earlier that summer, and was eliminated in the semifinals of the 100m after slowing down visibly in pain and walking the rest of the way through the finish line. His last major championship race was in the semifinals of the 100 m at the 2001 World Championships, where he injured himself again and was pushed off the track in a wheelchair.
In 2009, Surin became the new Canadian 50 metres record holder (40-45 age group) with a time of 6.15s at the McGill Open.[5]
In 2009, a biography cowritten by Bruny Surin and Saïd Khalil entitled Bruny Surin, le lion tranquille was published by Éditions Libre Expression in Montreal.[8][9][10] The book covers Bruny Surin recounting 17 years of his sports career.[11] In the book, Surin criticizes doping, describing it as a gangrene that ails athletics and all other sports.[12][13]
Surin emigrated to Canada with his family in 1975. His father lost his family in the 2010 Haiti earthquake. He has two daughters.[14] Surin ran for a seat on Laval City Council in a by-election on November 24, 2019, but lost by 82 votes.[15]
