Gilbert won his first medal at the 1993 World Championships, when the Canadian 4x100 m relay team finished in a third place. At the 1994 Commonwealth Games, Gilbert won the gold medal in 4x100 m relay and was fifth in 100 m. Gilbert also competed in bobsleigh at 1994 Winter Olympics, where he finished fifteenth in two-man bobsled and eleventh in four-man bobsled. As all modern sprinters muscularly built, Gilbert had particularly well-developed trapezius muscles.
At the AtlantaOlympics, the Canadian relay team weren't the hot favourites, although they won almost all the titles available during the last couple of years. At the 4x100 m relay final, the Canadian team beat United States by almost half a second, to establish itself the best relay team in the world. Gilbert also reached the quarterfinal of 100m.
After his retirement, Gilbert worked for a short time in CBC radio in Ottawa and is now a coach of Canadian 4x100 m relay team. He is also a coach for the Ottawa Lions Track & Field club, where he coaches sprints and relays.
