Canada’s Summer McIntosh wins 4th gold at worlds with 400m IM record, capping a dominant meet with 5 medals; now holds 13 career world championship medals.

A generational talent already among the top swimmers in the world, McIntosh may be the best swimmer to ever come out of Canada. She is a three-time Olympic champion, seven-time World Champion, holds six current world records and has set precedents that would have been unthinkable in Canadian swimming even a decade ago.
