TORONTO — Summer McIntosh has once again made waves—this time rewriting swimming history books at the 2025 Canadian Olympic Trials. The 18-year-old Toronto phenom delivered one of the most dominant performances in the sport’s recent memory, setting not one, not two, but three world records in a single meet.
On June 8 at the Toronto Pan Am Sports Centre, McIntosh stunned the crowd and the international swimming community by breaking the women’s 400 m freestyle world record with a time of 3:54.18, edging past the previous mark set by Australia’s Ariarne Titmus.
But she wasn’t done.
Over the course of the meet, she also established new world records in the 200 m individual medley (2:05.70) and the 400 m individual medley (4:23.65)—a feat only matched by swimming legends like Michael Phelps.
McIntosh breaks own 400 IM mark to set third world record in five days.
