"Over the past few years I’ve put my life into this," McIntosh said. "To achieve something like this, it was very unexpected. It was never in my dreams to do this tonight or even a few years ago. This just blows my mind."

McIntosh was competing in the trials to see who would represent Canada at the world championships in Japan this year as well as the Pan American Games in Chile.
