context_page_description: The Toronto Stock Exchange is a stock exchange in Toronto, Ontario, Canada. It is the 9th largest exchange in the world by market capitalization. Based in the EY Tower in Toronto's Financial District, the TSX is a wholly owned subsidiary of the TMX Group for the trading of senior equities. A broad range of businesses from Canada and abroad are represented on the exchange. In addition to conventional securities, the exchange lists various exchange-traded funds, split share corporations, income trusts and investment funds. More mining and oil and gas companies are listed on Toronto Stock Exchange than any other stock exchange.
context_section_description: The TSE moved on Bay Street in 1913 and in 1937 opened a new trading floor and headquarters in an Art Deco building, still on Bay. By 1936, the Toronto Stock Exchange grew to become the third largest in North America.
  In 1977, it launched the TSE 300 index and introduced the CATS (Computer Assisted Trading System), an automated trading system, and began to use it for the quotation of less liquid equities. In 1983, the TSE vacated its Art Deco headquarters on Bay Street and moved into the Exchange Tower. The old TSE building later became the Design Exchange, a museum and education centre. On April 23, 1997, the TSE's trading floor closed, making it the second-largest stock exchange in North America to choose a floorless, electronic (or virtual trading) environment.
  In 1999, through a major realignment plan, Toronto Stock Exchange became Canada's sole exchange for the trading of senior equities. The Bourse de Montréal/Montreal Exchange assumed responsibility for the trading of derivatives and the Vancouver Stock Exchange and Alberta Stock Exchange merged to form the Canadian Venture Exchange (CDNX) handling trading in junior equities. The Canadian Dealing Network, Winnipeg Stock Exchange, and equities portion of the Montreal Exchange later merged with CDNX. In 2000, the Toronto Stock Exchange became a for-profit company. In 2002 its acronym was rebranded to TSX and it became a public company. ·
