About Summer McIntosh

Summer Ann McIntosh (born August 18, 2006) is a Canadian competitive swimmer. A four-time World Aquatics champion, two-time Commonwealth Games gold medallist, and silver medallist at the 2024 Olympic Games, she is the current world record holder in the women's 400 metre individual medley.

McIntosh first drew recognition when, at age 14, she was the youngest member of the Canadian team for the 2020 Summer Olympics, where she achieved a notable fourth-place finish in the 400 metre freestyle. The following year she became the youngest World Aquatics champion in swimming in over a decade, and the first Canadian to win two gold medals at a single World Championships, for which she was dubbed a "teen swimming sensation." In March and April 2023, in the span of five days, she set her first and second world records, in the 400 metre freestyle and 400 individual medley events, at the Canadian national trials. She won her first Olympic medal in 2024, silver in the 400 metre freestyle.
