Andre De Grasse

Raised in Markham, Ontario, he went to St. Marguerite Bourgeoys Catholic Elementary School in Scarborough from kindergarten to the second grade and later transferred to Mother Teresa Catholic Elementary School in Markham to continue until grade eight where he won his first race in 2006. He also attended Father Michael McGivney Catholic Academy and Milliken Mills High School. De Grasse is a Roman Catholic having been influenced by his mother's faith. He has the word "hope" and a prayer tattooed on his arm.

In his first race De Grasse ran wearing basketball shorts and flat shoes and using no starting blocks, he secured a time of 10.9 seconds in a 100 m race. He was spotted by future coach Tony Sharpe who noticed his potential because of this. At the 2013 Canada Games De Grasse won three gold medals in the 100, 200, and 4×100-metre relay. He attended Coffeyville Community College in 2013 and 2014 before transferring to USC for his junior season in 2015. In 2016, he established Andre De Grasse Holiday Classic Basketball Tournament, a charity event that supports Andre De Grasse Family Foundation. In September 2017, he appeared at WE Day, a WE Charity event in Toronto. De Grasse also created and participates annually in a basketball tournament named "Holiday Classic at Markham" at Pan Am Centre. All proceeds from the tournament go to the Andre De Grasse Family Foundation.

De Grasse's legal 100 m time of 9.97 to win the Pac-12 championship in May 2015 was the first time he ran under 10 seconds. At the 2015 100 m NCAA championships De Grasse ran a wind-assisted time of 9.75 to win; the wind was +2.7 m/s. The 9.75 made him the seventh fastest man in the world and fastest Canadian in any conditions. Also at the 2015 NCAA Championships, De Grasse produced a wind-aided 19.58 (+2.4) 200 metres. That was nearly a half a second faster than his own national record set four weeks earlier. After the race, with encouragement from his friends to keep going in the pursuit of titles, he said "So I ask myself...world champion? Olympic champion? Why not me? I've come this far, and I've only scratched the surface. I want to keep it going. Track is fun to me, and as long as it stays this way, I expect to keep getting better."

The 2015 World Championships in Athletics took place in Beijing. At the event De Grasse ran sub-10-second times in the heat and semi-final on his way to the eighth lane in the final. There, De Grasse tied for the bronze medal with American Trayvon Bromell in the 100m, running a 9.92. He became the first Canadian to win a medal in track's marquee event since Bruny Surin raced to silver in 1999. After the final De Grasse said "I didn't know who had won the race, I didn't know you could actually tie with someone for a bronze medal. So I am very happy for Trayvon and proud of myself to come away with a personal best. To race against these guys and make the final, I couldn't end the season any better than that. I can't let [the lane assignment] distract me. At the end of the day, it's the 100m final. This was the biggest race of my life so I wasn't going to think about no lane assignment. I had a lot of confidence after the semi-finals, being that close to Bolt, and that raised my confidence for the final." De Grasse also participated in the 4 × 100m relay where he won a second bronze medal, running a 38.13 together with Aaron Brown, Brendon Rodney, and Justyn Warner.

De Grasse turned professional in December 2015, signing with Puma for $11.25 million.

In July 2016, he was named to Canada's Olympic team. De Grasse advanced to the finals of the 100m at the 2016 Summer Olympics after running a time of 10.04 in his heat and then 9.92 in the semi-finals. De Grasse placed third and received the bronze medal behind Usain Bolt and Justin Gatlin, at 9.91 seconds, which was his personal best time. He was the first male athlete to win a medal for Canada at the 2016 Summer Olympics. Bolt was visibly supportive of De Grasse during both the semis and finals, hugging him after the race and saying to reporters "He came through again. He's going to be good, he runs just like me, I mean he's really slow at the blocks but when he gets going, he gets going." De Grasse said of his relationship with Bolt after that "We were just having some fun. Me (sic) and Usain met back in January, we did a lot of things together. He feels like I'm the next one, and now I'm just trying to live up to it." Former Canadian Olympic Champion Donovan Bailey was seen jumping up and down in the CBC Sports studio, cheering on De Grasse. After, he said, "I'm shaking. This is great for track and field in Canada."

De Grasse's success at the Olympics led to his winning the Lionel Conacher Award as the Canadian Press' male athlete of the year, and be presented with the Rising Star Award by the IAAF. In April 2017 De Grasse was a recipient of a Harry Jerome Award.

On January 10, 2018, De Grasse was named to Canada's 2018 Commonwealth Games team. However, he had withdrawn before the games began due to his hamstring injury.
