Summer Ann McIntosh (born August 18, 2006) is a Canadian competitive swimmer renowned for her versatility and dominance in medley, freestyle, and butterfly events. She made her Olympic debut at age 14 at the Tokyo 2020 Games, finishing fourth in the 400m freestyle and setting multiple Canadian records. McIntosh quickly rose to international prominence, becoming the youngest Canadian world champion in swimming history and the first to win multiple golds at a World Aquatics Championships[1][2][4]. At the 2024 Paris Olympics, McIntosh made Canadian Olympic history by winning three gold medals in a single Games—the 400m individual medley, 200m butterfly, and 200m individual medley—and a silver in the 400m freestyle. She set Olympic records in the 200m butterfly and 200m individual medley, tying the Canadian record for most medals won at one Summer Olympics and serving as one of Team Canada’s Closing Ceremony flag bearers[1]. Her 2024 performance earned significant international acclaim, with media outlets highlighting her as a generational talent. McIntosh holds multiple world records, including in the 200m and 400m individual medley and the 400m freestyle in long course, as well as several in short course events. Notably, in 2023 at the Canadian Trials, she broke world records in the 400m freestyle and 400m individual medley, becoming the first swimmer aged 16 or younger to hold both records simultaneously. This feat made her the first Canadian since 1984 to hold two long-course world records at once[1][2]. Daughter of former Canadian Olympic swimmer Jill Horstead, McIntosh began competitive swimming at a young age and has set over 50 Canadian age-group records. She trains in Sarasota, Florida, and is recognized as one of the most successful and promising swimmers in Canadian history, with multiple national and international awards for her performances[2][4][5].
