"I was just wondering if the winter road that has been mentioned requires a permit .Apparently the natives have been using something they say is a winter road .

And can Noront get heavy equipement such as bulldozers heavy hauler trucks .and loaders in with out a winter road ."

Winter roads are a yearly thing. A new winter road on a new route would have to be permitted. All manner of heavy equipment is run across ice roads which cross all manner of waterways. The ice thickness due to weather conditions has be checked for safe travel. Cold weather means workable roads.
