Andre De Grasse is skipping the Canadian championship in Ottawa due to tightness in his hamstring.

De Grasse, a seven-time Olympic medallist and the anchor of Canada's 4x100-metre gold-medal team at the 2024 Paris Summer Games, said the injury will keep him from competing this weekend.

"Unfortunately, I won't be competing this weekend," De Grasse told CTV News.

"I picked up a little bit of tightness a couple of weeks ago with my hamstring so I'm going to play it safe and not do any extra damage I need to do. I'll just be here this weekend signing autographs, doing meet-and-greets, taking pictures and just hanging out with my fans and making sure everyone has a chance to see me."

However, the 200m Olympic champion from 2021 said he'll be good to for the  World Athletics Championship when the event takes play in Tokyo from Sept. 13-21.

"I have about five-six weeks, so I should be good. It's just a little bit of tightness in my hamstring so I don't want to risk it and make it worse," De Grasse said. "I've been getting a lot of treatment from the team doctors here, making sure I'm ready to go when it matters."

On the track, sprinter Audrey Leduc of Gatineau, Que., won the senior women's 100-metres championship on Friday night, clocking 11.06 to top the eight-runner final at the Canadian track and field championships.

The 26-year-old Leduc, who holds the Canadian records in the 100-metres (10.95) and 200 metres (22.36) — both set in 2024 — finished just ahead of Olympian Sade McCreath (11.09) of Ajax, Ont., and Jacqueline Madogo (11.21) of Ottawa, who became the 200-metres national champion in 2023.

Olympian sprinter Duan Asemota of Montreal won the men's 100-metre championship in a 10.12 photo finish, just edging out Aaron Brown (10.13) of Toronto, who was part of Canada's 4x100-metre relay team that won gold in 2024. Eliezer Adjibi (10.21) of Ottawa finished third.
