Municipal police received a 911 call early Saturday morning and arrived to find the child unresponsive in a bed.
The child was pronounced dead at a local hospital.
A spokesperson says the investigation was turned over to the provincial police because the context of the death was suspicious.
Police are currently interviewing witnesses in order to determine whether a criminal act took place.
The child's mother was also questioned.
Some media outlets have reported that the child was a girl, but police haven't confirmed that.
The spokesperson said all deaths involving young children are considered suspicious.
The child's body has been transported to Montreal where an autopsy will take place.
