How old is Summer McIntosh? Comparing Canada swimming star to Katie Ledecky at age 17 | Sporting News

Summer McIntosh does not just represent the future of Canadian swimming — she is the now.

The native of Toronto put her name on the Olympic map three years ago in Tokyo. McIntosh was the youngest Canadian at the 2021 Olympics, but she did more than just show up. She showed out, finishing fourth in the women’s 400m freestyle and setting a new Canadian national record with a time of 4:02.42.

While McIntosh did not earn a medal then, the teenager is one of the favorites to finish atop the podium now. McIntosh is a threat to take the gold medal away from Team USA’s Katie Ledecky, who also starred on the Olympic stage at a young age.
