The Wapusk Trail is a winter road that starts in Gillam, Manitoba, where Manitoba Provincial Road 280, between Thompson, Manitoba and Gillam, Manitoba, ends.
The Wapusk Trail is rebuilt every year out of snow, from Gillam, Manitoba, eastward first, to Shamattawa, Manitoba, then to Fort Severn, Ontario. It then curves slightly south, but still east, through Polar Bear Provincial Park, along Hudson Bay, to Peawanuck, Ontario, about 30 kilometers inland.
The road is very narrow in some sections. There is little room for error on this road. The first 90 km of the road west from Fort Severn is the worst part of the road when the wind is blowing. The road is difficult and it’s a nightmare in the wet or dark (or both). The number of trucks averages is between 30 to 40, with 44 trucks being the record number of trucks in one year, transporting consumer goods, fuel and construction materials. It takes about 12 to 17 hours to get to Gillam, depending on the conditions. Conditions can change quickly and be harsh.
For most people in Fort Severn, or Peawanuck, this is their only means of transport, other than by plane. "Wapusk" is Cree for "White Bear", and there are many polar bears around. The communities of Shamattawa, Manitoba, and Fort Severn and Peawanuck, Ontario, on the Wapusk Trail are mostly Cree.
