Regarding the underground city in Canada...
Montreal...
With over 32 km of tunnels spread over an area of twelve square kilometres, the 60 residential and commercial complexes comprise 3.6 square kilometres of floor space, including 80% of all office space and 35% of all commercial space in downtown Montreal. Services include shopping malls, hotels, banks, offices, museums, universities, seven metro stations, two commuter train stations, a bus terminal and the Bell Centre. There are more than 120 exterior access points to the underground city. Some 500,000 people use the underground city every day, especially to escape the traffic and/or Montreal's harsh winters and hot summers.
