2011-12: Sparks assumed the lion's share of the goaltending duties for the OHL's Guelph Storm after splitting time with 20-year-old Brandon Foote early in the season. He played a career-high 59 games and was 27-25-4 with 5 shutouts and had a 3.11 goals against and .907 save percentage.

He won a gold medal at the 2013 U20 World Junior Championship in Ufa but did not see any action as the USA's third goalie behind John Gibson (Anaheim) and Jon Gillies (Calgary).
Standing 6’3 Garret Sparks frame allows him to be a very good blocking goaltender. He cuts down the angles well and is able to track play through traffic. In 2012-13 we saw a more consistent Sparks for the Guelph Storm; an area of concern in prior seasons.
Sparks will be looking to win over the Toronto Marlies backup position for the 2013-14 season.
