Northwest Territories Department of Infrastructure (DOI)

The Northwest Territories Department of Infrastructure manages approximately 2,200 kilometers of all-season roads and operates over 1,400 kilometers of winter roads — including seasonal ice roads — that are the lifelines for remote communities in Canada's north. The primary all-season freight corridor is Highway 1 (the Mackenzie Highway) and Highway 3 connecting Yellowknife to southern Canada. Ice roads, particularly the iconic Tibbitt to Contwoyto Winter Road, are critical for supplying diamond mines and northern communities. The department administers commercial vehicle regulations, manages critical river ferry crossings during open water season, and coordinates with airlines for intermodal freight in areas inaccessible by road year-round.
