Gabriel (Gabe) Mastromatteo


Gabe Mastromatteo made his Olympic debut at Tokyo 2020 where he was a finalist with the men’s 4x100m medley relay, swimming the breaststroke leg.

Mastromatteo qualified for his first senior national team by winning silver in the 50m and 100m breaststroke events at the 2019 Canadian Trials. Later that summer, he made his debut at the World Aquatics Championships in the 200m breaststroke. He would also compete at the 2019 World Aquatics Junior Championships, winning silver in the 50m breaststroke and bronzes in both the mixed and men’s 4x100m medley relays. He came close to another medal in the 100m breaststroke, finishing fourth. 

That was Mastromatteo’s second appearance at the world juniors. In 2017, he won gold with the mixed 4x100m medley relay and was a finalist in the 50m breaststroke. It was also in 2017 that Mastromatteo won four medals at the Canada Summer Games in Winnipeg, including three gold. Individually, he broke the Canada Games record in the 50m breaststroke to stand atop the podium. He was also a gold medallist in the 4x50m and 4x100m medley relays.

In 2018, Mastromatteo won gold in the 100m breaststroke and was a finalist in the 200m breaststroke at the Junior Pan Pacific Championships. In 2019, he committed to attending the University of Toronto and competing for the Varsity Blues. He was named U Sports Outstanding Male Swimmer of the Year in 2023 after winning gold in the 50m breaststroke and 100m breaststroke at the U Sports Championships while setting U Sports records in both events.
