[6] Drouin's personal best jump of 2.40 m (7 ft 10+1⁄4 in), set in 2014, is the Canadian record and ranks him joint eighth on the overall list.

[8] Drouin first learned to high jump in kindergarten in Corunna, Ontario when his teacher introduced the sport to the class.

[9] He first achieved international success when he won the 2009 Pan American Junior Championships in high jump for Canada, clearing 2.27 m. He would continue on in his career competing in the NCAA with the Indiana Hoosiers track team where he would be the first Hoosier athlete to win an NCAA championship in high jump.

[13] Drouin was almost unable to get to the point where he could compete at the Olympics, having torn three ligaments in his foot in 2011 after jumping in a meet in Mississippi State and only returned to competition in April 2012.

[14] Drouin initially won the bronze medal at the 2012 Summer Olympics in London, England with a jump of 2.29 metres.

At these games he again found himself in the bronze competition with a personal best and a national record 2.38 m, but was unable to achieve 2.41 m. In contrast to London he stood in third place with Mutaz Barshim in second and the 2013 world leader Bohdan Bondarenko winning the gold.

[16] Drouin had a lot to say of the moment but felt he could achieve more: "I wanted to prove this year that I deserved to be on the podium in London 2012, feels good to have accomplished that goal.

"[16] One month after the Worlds, Drouin won his first major international title at the 7th edition of the Francophone Games held in Nice, France on Saturday September 14, 2013.

[18] Building on his new breakthroughs, the following outdoor season saw Drouin reach new heights when he bettered his Canadian record jumping 2.40 at the 2014 Drake Relays event in Des Moines, United States.

Drouin was proud of reaching what he deemed a prestigious height, saying, "That is a huge barrier distance, I think, for any elite high jumper.

"[23] At the 2016 Summer Olympics in Rio de Janeiro, Drouin jumped a season best height of 2.38 metres to win the gold medal, defeating Barshim and Bondarenko.

Drouin was the first Canadian to win a gold medal in a field sport since Duncan McNaughton, who also won the high jump at the 1932 Summer Olympics in Los Angeles.

[9] Drouin commented on the technique to The New York Times saying, "You see, jumpers try to run as fast as they can, and then they put their foot down and their leg isn't able to handle it.

"[9] Following the 2016 Rio Olympics, Drouin began training for decathlons with the goal of making the 2018 Commonwealth Games team in the multi-event.

"[26] On April 7, 2017, at the Sam Adam Multi Event meet in Montecito, California, he set the world decathlon best in the high jump at 2.28 m (7 ft 5+3⁄4 in).

Unfortunately the injury to his achilles tendon forced him, like fellow Canadian and medal favourite Andre De Grasse, to miss the championships.
