The Canadian men's and women's 4x100-metre relay teams qualified for the 2025 World Athletics Championships with performances on Saturday at the World Athletics Relays in Guangzhou, China.

The men's team of Andre De Grasse, Aaron Brown, Brendon Rodney, and Jerome Blake finished second in their heat to qualify for Sunday's final, but more importantly for them, clinch a spot at the world championships in Tokyo.

"We handled business," Brown said after the race. "The first order of business, like [head coach] Glenroy [Gilbert] said, was to qualify for Tokyo. So we checked that box off."

Canada's Olympic champion men’s 4x100m team, featuring Aaron Brown, Jerome Blake, Brendon Rodney and Andre DeGrasse finish second in their heat to move to the finals at the 2025 World Athletic Relays in Guangzhou, China.

That automatic qualification was in doubt for the reigning Olympic champions until De Grasse lifted his team in the anchor leg. The Markham, Ont., native held off Australia and the Netherlands to cross the line in 38.15 seconds and secure second place behind Japan (37.84).

"We ran a bit shaky, everyone kind of felt a little bit flat," Brown said after the race. "But it's the first round, and if Paris tells us anything, we make magic in the finals.

"We adjust, we watch the tapes and see what we did wrong, and clean up for the finals and get ready to put on a show."

The Canadian women's 4x100m race unfolded much like the men's. Thanks to a blazing-fast anchor leg, Sade McCreath, Marie-Éloise Leclair, Catherine Léger, and Audrey Leduc secured their spot in Tokyo.

Canada's women's 4x100m team, featuring Sade McCreath, Marie-Eloise Leclair, Catherine Leger and Audrey Leduc finish second in their heat to move to the finals at the 2025 World Athletic Relays, and world championships.

Canada was in fourth place when Leduc took the baton but she powered past the Italian and Dutch runners to secure a second-place finish (43.11) and clinch automatic qualification for the world championships and Sunday's final.

"It's a relief," Leduc said about qualifying for Tokyo. "It's very exciting to get there on the first try, to do it in the heats and go to the final without having to do the other [repechage] round."

Women's 4x400m advance

The Canadian women's 4x400m team also booked a spot a worlds. Jasneet Nijjar, Zoe Sherar, Lauren Gale, and Madeline Price finished fourth in their heat, but their time (3:37.28) was fast enough to qualify for Sunday's final and the world championships.

Canada's women's 4x400m team, featuring Jasneet Nijjar, Zoe Sherar, Lauren Gale and Madeline Price qualify for the semi finals on time in their heat to move to the finals, and world championships.

In the debut of the mixed 4x100m event, the Canadian team advanced to the final by posting the top time across all of Saturday's heats.

Gabrielle Cole, Jacqueline Madogo, Duan Asemota and Eliezer Adjibi combined to finish in 40.90 to book their spot in the final. 

The mixed 4x100m is not being contested at this year's world championships, so no qualification was on line, but Asemota said the team is still looking to impress at the World Relays.

"Now that we got our feet wet, we're ready to go into the finals and let it all loose, and make Canada proud," he said.
