The boy was found unconcious in a backyard pool during a family gathering Saturday evening, according to Quebec provincial police.
The family member revived the toddler and he was taken to hospital as a precaution. He was later released.
It's the third incident involving a young child and a backyard pool in Quebec in the past week.
Two other children died after they were found unconscious in pools in Laval and Kirkland.
According to the Lifesaving Society, backyard pools are the number one location where children under age five drown.
There have been 41 drownings in Quebec to date this year, 12 more than in 2011.
