Mary-Sophie Harvey of Trois-Rivières, Que., was third in 3:54.88 to pick up her first international medal.

McIntosh continued her fantastic year that saw her win three gold medals and a silver at the 2024 Paris Olympics.

She is also set to compete in the 400-metre individual medley, 200-metre butterfly, 200 backstroke and four relays in Budapest.

The short-course championship takes place in a 25-metre pool, as opposed to the Olympic-standard 50-metre pool. McIntoshsaid before the event that competing in the shorter pool will give her a chance to work on her turns.

Australia's Ariarne Titmus holds the 400 freestyle long-course world record, which was previously held by McIntosh.
