The OPP is urging snowmobile enthusiasts to be careful.
There have already been five fatal motorized snow vehicle collisions in Ontario since the start of the season.
Police warn snowmobilers to exercise caution at all times while out enjoying what should be a safe winter recreational activity.
This is especially important during heavy snowfall, high winds, when snow banks are present and when visibility becomes obscured or is reduced to zero.
The Ontario Federation of Snowmobile Clubs (OFSC) provide designated trails that are marked, mapped, maintained and patrolled for the safety and enjoyment of all snowmobilers.
By avoiding closed trails and not riding on roads, lakes, unfamiliar terrain and private property, snowmobilers can greatly reduce their risk of getting into trouble.
