On March 15, 1999, the Vancouver Stock Exchange (VSE), the Alberta Stock Exchange (ASE), the Toronto Stock Exchange (TSE) and the Montreal Exchange (ME) announced that they had signed a Memorandum of Agreement to restructure the exchanges.
Through a realignment plan, the Toronto Stock Exchange became Canada's sole exchange for the trading of senior equities. The Montreal Exchange assumed responsibility for the trading of derivatives and the Vancouver and Alberta Stock Exchanges 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.
On November 26, 1999 the B.C. Securities Commission recognized CDNX as an exchange in British Columbia under section 24(b) of the Securities Act. Notice and Interpretation Note (NIN) 99/45 summarizes the instruments used by the Commission in connection with the recognition of CDNX.
In 2001, CDNX was taken over by the TSE.
On April 8, 2002, the TSE re-branded its organization and adopted the acronym TSX. The CDNX was renamed TSX Venture Exchange.
On June 11, 2008, the TSX Group changed their name to the TMX Group Inc.
The TMX Group's key subsidiaries operate cash and derivative markets for multiple asset classes including equities, fixed income and energy.
