Ontario Federation of Snowmobile Clubs is a non-profit organization responsible for the majority of all groomed snowmobile trails in the province of Ontario, Canada.
The Ontario Federation of Snowmobile Clubs (OFSC) is a volunteer-based, non-profit organization based in Barrie, Ontario. The OFSC represents 231 member snowmobile clubs who operate the world's largest recreational trail system — 39,000 kilometres of snowmobile trails that link most snowbelt communities in Canada's largest province. Ontario law requires that recreational and touring sledders purchase a Snowmobile Trail Permit from the OFSC to access or ride OFSC trails during the winter.
