Roared on by a hometown crowd in Toronto on Thursday, the 17-year-old sensation got to the wall first in a time of four minutes 24.38 seconds, smashing her old mark of 4:25.87 set last year.
McIntosh, a two-time world champion in the 400 IM, was just under world-record pace midway through the race and picked up the tempo on the breaststroke leg to open a two-second gap with 100 metres to go.
"I was really just focusing on having fun with the race and kind of taking it 100 metres at a time because it's a pretty mentally challenging race," said McIntosh, who trains in Sarasota, Florida.
"Whenever I get to race in front of a big crowd, I think it really gives me a lift. Just that complete adrenaline rush is awesome."
It was McIntosh's third win at the Olympic trials, also taking top spot in the 400m and 200m freestyle events.
McIntosh is set to appear in her second Olympics that could include potential showdowns with American great Katie Ledecky and Australian double Olympic champion Ariarne Titmus.
