An 11-year-old girl was behind the wheel of a sports utility vehicle on Friday when it rolled over, killing a 12-year-old female passenger near Mackenzie.
A 41-year-old man was also in the 1994 Jeep YJ at the time of the crash, which occurred around 7 p.m. on Causeway forest service road.
Police are investigating what led to the crash and have not yet decided whether or not charges will be recommended.
"The investigation is ongoing and we're still examining all the circumstances involving the incident," RCMP spokesman Cpl. Dan Moskaluk said.
The North District traffic specialists are assisting Mackenzie RCMP detachment in conducting the probe. Moskaluk said it was too early to say how long the investigation could take.
"You have a collision analyst report to be received, vehicle inspection and just the whole investigation itself looking at all the circumstances," Moskaluk said.
The names of those involved in the incident have not been released and police have not said if those involved in the incident are related.
The 12-year-old girl was declared dead at the scene and the road was closed for 10 hours due to the investigation.
The impact of the crash on the community with a regional population of 4,500 has been devastating, according to police.
"The impact on the community and in our elementary and high schools has been significant," Mackenzie RCMP detachment commander Sgt. Syd Lecky said in a news release. "Investigators and RCMP victim assistance workers continue to work with the community in providing support to the affected families."
