Believe me, the Government of Ontario will pickup the tab for the road. They started this planning back in 2005 and it is in high gear right now. I personally had conversations with one of their people a month ago.
This is from 2005 Ontario Government Release for just one of the areas they are looking at AND there working group are very aware of Noront and exploration now going on in James Bay lowlands:
The Northern Ontario Heritage Fund Corporation (NOHFC) will provide $146,297 to enable the Northern Roads First Nations Transportation Authority to undertake the first stages of planning for a proposed all-weather road system. The system would extend northwards from the end of the existing all weather road north of Red Lake to Sandy Lake First Nation, linking Deer Lake, Keewaywin, North Spirit, McDowell Lake and Poplar Hill First Nations.
These remote communities are currently only accessible by air service and by seasonal winter roads. The mandate of the transportation authority is to manage and oversee all the activities associated with the planning, design, development, construction, operations and maintenance of the proposed all weather road. The project’s initial steps include assessing economic impacts and benefits, strategic planning and defining the roles and responsibilities.
