Downtown Montreal is the central business district of Montreal, Quebec, Canada. It lies at the foot of Mount Royal, a major urban park and popular tourist destination, and extends toward the Saint Lawrence River. The downtown area contains most of the city''s skyscrapers which, by law, cannot be greater in height than Mount Royal. The two tallest of these are the 1000 de La Gauchetière and 1250 René- Lévesque, both of which were built in 1992. The Tour de la Bourse is also a significant high-rise and is home to the Montreal Exchange that trades in derivatives. The Montreal Exchange was originally a stock exchange and was the first in Canada. In 1999, all stock trades were transferred to Toronto in exchange for an exclusivity in derivatives trading.
