A 10-year-old boy died at a home in Brampton, Ont., on Friday afternoon.
Paramedics and police responding to a 911 call shortly after 5 p.m. found the child unresponsive in the home on Homeland Court, in the Dixie Road and Howden Boulevard area.
The boy was declared dead at the scene.
Police are investigating and an autopsy is being conducted, though results aren't expected for a couple days.
Peel Regional Police spokesman Const. Adam Minnion said the boy's body showed no obvious signs of trauma.
"That's what makes this a little bit more challenging for us, is it's not clear cut for us to walk in and go, 'There's been an obvious assault taken place, we can make arrests right away,' " Minnion said.
"Generally speaking… most people would think that a 10-year-old child is in relatively good health, so we have to make sure that the death either occurred naturally or whether or not there was some type of neglect or assault."
Police would not say who called 911.
Minnion said police constables will be posted around the home until it's determined whether the boy's death was from natural causes or involved potential foul play.
The city of Brampton borders Toronto to the northwest.
