of RCAF Station North Bay (in 1966 retitled "Canadian Forces Base North Bay" and in 1993 as "22 Wing/Canadian Forces Base North Bay") took three years, during which it became the largest industry in the community: a status it held for more than four decades. In October 1963, the North American Air Defence Command (NORAD) opened its Canadian operations centre at the base. Manned by American as well as Canadian military personnel, the centre, situated 60 storeys underground to withstand a nuclear strike, monitored Canada's northern, east-central and Atlantic airspace, identifying and tracking all air traffic in this airspace, and responding to airborne emergencies, crime, and suspicious, unknown and potentially hostile aircraft. In 1983 this responsibility was expanded to all of Canada, and in October 2006 the base's NORAD operations (as of 1981, called North American Aerospace Defence Command) moved into a new, state-of-the-art facility above ground, where it continues to provide surveillance, identification and tracking of aircraft, and warning and response to emergencies, attacks and other crises, for the air sovereignty of Canada and North America. In summer of 2013, the base commenced surveillance of space via SAPPHIRE, Canada's first military satellite, that was launched into orbit from India in February. Beginning in the 1990s, the base weathered a series of massive cuts by the federal government, and at one point was earmarked to close. Subsequently, a large portion of its infrastructure, including all of its airfield assets, such as hangars, fuel depot and control tower, were sold or demolished. By the 21st century, the base was no longer the city's top industry. One by-product of the air base's creation in 1951 was the extension of the existing airport's runways to handle the largest military aircraft. The long runways at North Bay have been maintained as an alternate landing site for Toronto's Pearson International Airport and were used during the September 11 crisis as an emergency landing site for several international aircraft. It was also a designated emergency field for NASA's Space Transportation System, better known as the Space Shuttle. On March 17, 2007, North Bay was announced as the winner of 2007 Kraft Hockeyville contest. North Bay received $50,000 to upgrade their local arena, Memorial Gardens, and also hosted an NHL pre-season game between the New York Islanders and the Atlanta Thrashers. Geography North Bay is located approximately north of Toronto, and differs in geography from Southern Ontario
