Officers with the Greenstone detachment of the OPP are reporting a tragic death over the recent long weekend.
Police say a 16-year-old girl was killed in an incident involving an all-terrain vehicle on Saturday evening.
OPP officers did not release details of the fatality until Wednesday.
The teen was from St. Catherines, Ont., and was off-duty from her summer job as a counsellor at Camp Auger, which is just outside Geraldton, when the incident occurred.
Police say she was not wearing a helmet at the time.
