Justyn Warner

In August 2013 Warner anchored his Canadian teammates Gavin Smellie, Aaron Brown and Dontae Richards-Kwok to a bronze in the same men's sprint relay event at the 2013 World Championships in Athletics in Moscow, after Great Britain was disqualified for a baton exchange infraction.

In 2012, Warner qualified in the 100m for the 2012 Summer Olympics by winning his first Canadian championship in 10.15s. That also qualified him to be a member of the 4 × 100 m relay team. At the Olympic Games, Warner finished 13th overall running a personal best of 10.09s twice in both the heat and the semi-final. Next up was the 4 × 100 m relay with Gavin Smellie, Oluseyi Smith, Jared Connaughton & Warner anchoring. In the final, the Canadian relay team arrived in third place and initially believed they had won bronze but they were disqualified when officials judged that Connaughton had stepped on the lane line just before passing the baton. The relay team from Trinidad and Tobago were awarded the bronze.

Warner has a younger brother Ian who graduated from Iowa State University. His younger brother finished right behind him at the 2012 Canadian Olympic Trials with a time of 10.20.

Warner received a full scholarship to Texas Christian University where he competed in the NCAA as a Horned Frog under Darryl Anderson. He was a three-time All-American. He graduated TCU in 2009 with a bachelor's degree in Kinesiology.

A year later on August 16, 2006, he claimed the silver medal in the 100 m at the 2006 World Junior Championships in Athletics, held in Beijing, China, in a time of 10.39.

Warner is a graduate of Birchmount Park Collegiate Institute in Scarborough, Ontario. He was a double-sport athlete playing football and running track, where he was an outstanding sprint athlete. In 2005, his senior year he won four provincial O.F.S.A.A titles on the track: 100m, 200m, 4 × 100 m, and 4 × 400 m.

On July 30, 2005, he finished second in the 100 m at the 2005 Pan Am Junior Games, held in Windsor, Ontario, in a time of 10.26, a new Canadian Junior record.
