city's urban core, while rural areas in the city continue to be served by Hydro One. Transportation Public transportation The city maintains a bus-based public transit system, GOVA, transporting 4.4 million passengers in 2012. The year 2000 marked the most significant change in Greater Sudbury's local transit history, as outlying townships were annexed into the municipality to form Greater Sudbury, expanding Greater Sudbury Transit's service area to one larger than most Ontario municipal and regional public transit agencies. The Downtown Transit Center is the primary hub for local transit in Sudbury. Air The Greater Sudbury Airport maintains two paved runways and in length and serves 270,784 passengers per year (2017). The airport is served by three regional carrier lines: Air Canada Express to Toronto Pearson International Airport, Porter Airlines to Billy Bishop Toronto City Airport and Bearskin Airlines to several destinations in Northern Ontario including North Bay, Sault Ste. Marie, Timmins and Thunder Bay. Intercity transportation Several different agencies provide intercity transportation to Sudbury. Via Rail's Sudbury–White River train (a remnant of the old Lake Superior passenger service to Thunder Bay) serves a number of remote interior communities, some of which are not accessible by road, from the downtown Sudbury station. To the north and east of the city, Capreol station and Sudbury Junction station are stops on Via Rail's transcontinental passenger service, the Canadian, which passes through the area twice a week in each direction. Intercity motor coach service is available at the Sudbury Ontario Northland Bus Terminal, which is a stop for Ontario Northland motor coaches. Destinations include North Bay, Sault Ste. Marie, Hearst, Barrie, Toronto, and Ottawa. Roads and highways There are three highways connecting Sudbury to the rest of Ontario: Highway 17 is the main branch of the Trans-Canada Highway, connecting the city to points east and west. An approximately segment of Highway 17, from Mikkola to Whitefish, is freeway. The highway bypasses the city via two separately-constructed roads, the Southwest and Southeast Bypasses, that form a partial ring road around the southern end of the city's urban core for traffic travelling through Highway 17. The former alignment of Highway 17 through the city is now Municipal Road 55. Highway 69, also a branch of the Trans-Canada Highway, leads south to Parry Sound, where it connects to the Highway 400 freeway to Toronto; Highway 400 is being extended to Greater Sudbury and is scheduled for completion
