Peel police confirmed the relationship of the victims Monday morning.
Emergency crews were called to Elmvale Avenue and Conestoga Drive just after 2 a.m. for a single-vehicle crash.
Police said a vehicle crashed into a tree in the area and burst into flames.  After the fire was extinguished, three occupants of the vehicle were located and pronounced dead at the scene.
The siblings have been identified to CTV News Toronto by their uncle Alman Blackman as 19-year-old Tirzah, 17-year-old Judah and 16-year-old Pharaoh Blackman.

Anyone who knows them would tell you the same thing: they all had hearts of gold,” Blackman said Monday. “It’s a shame they didn’t have the chance to make the mistakes we all did. Everyone has stories, teenagers, reckless things… it’s a shame they didn’t get to make the mistakes we all do.” Blackman added that the victims’ mother, as well as their other siblings, are reeling from the loss. “Everybody’s sad, everybody’s sad. Nobody feels good,” Blackman said. Prior to the crash, police believe the white Honda Civic was traveling south and left the road for an unknown reason. The front of the vehicle sustained significant damage after the impact and a large amount of debris was scattered around the crash site.
