McIntosh first drew international recognition when, at age 14, she was the youngest member of the Canadian team for the 2020 Summer Olympics, where she achieved a fourth-place finish in the 400 meter 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 meter freestyle and 400 individual medley events, at the Canadian national trials. McIntosh's performance at the 2024 Summer Olympics, in which she won four individual medals (three gold and one silver), further increased her fame, with Time dubbing it the "Summer of Summer".

Accolades bestowed upon McIntosh include the Northern Star Award as the top Canadian athlete of 2024, three consecutive Bobbie Rosenfeld Awards as The Canadian Press' choice for Canadian female athlete of the year (2023–2025), and two World Aquatics Female Swimmer of the Year honors (2024–2025).
