As a junior rider, Canadian Eric Lamaze showed great promise to emerge as one of Canada's great international equestrians. He entered grand prix jumping in 1992 and, within one year, was named to the Canadian national team, making his first major appearance at the 1994 World Equestrian Games. His career was nearly derailed in 1996, however, when his drug tests for the 1996 Summer Olympics came up positive for cocaine. He received a four-year suspension and was barred from participating in the Games. It was later decided that his personal circumstances – growing up with a mother who dealt drugs most prominent among them – were sufficient to have his ban lifted in time to participate at the 1998 World Equestrian Games. One year later he picked up a bronze medal in the team jumping event at the 1999 Pan American Games.

Lamaze was then offered an opportunity to represent his country at the 2000 Summer Olympics, but received lifetime banishment from the sport after testing for a forbidden stimulant. Believing his career to be over, he went to a party immediately after hearing his result and smoked a cigarette laced with cocaine. Less than two days later, however, the test that he failed was stricken from the record and he was given another opportunity to pass it and attend the Games. He failed again, this time for cocaine, and although he again avoided a lifelong ban, Canadian officials still refused to send him to Sydney.

Lamaze made one more comeback attempt and, by 2008, had become the first Canadian equestrian in two decades to be ranked among the top ten in the world. He also had two more Pan American medals under his belt from 2007: silver from the team jumping competition and bronze in the individual. In 2008 he finally made it to the Olympics and did not disappoint, capturing gold in the individual jumping tournament and silver in the team version. Although his champion horse Hickstead died in November 2011, Lamaze decided against retirement in the hopes of finding another to compete with for the 2012 Summer Olympics, where he finished 29th in the individual event and 5th in the team competition.
