The TSX Venture Exchange is a stock exchange in Canada. It is headquartered in Calgary, Alberta and has offices in Toronto, Vancouver, and Montreal. All trading through the Exchange is done electronically, so the Exchange does not have a "trading floor". It was previously known as the Canadian Venture Exchange (CDNX), but in 2001 the TSX Group (now known as the TMX Group) purchased it and renamed it.

The TMX Group also owns the Toronto Stock Exchange (TSX). The Toronto Stock Exchange is the senior equity market, while the TSX Venture Exchange is a public venture capital marketplace for emerging companies.

As of November 2010, the TSX Venture Exchange had 2,364 listed companies with a combined market capitalization of $60,811,203,235.

The Canadian Venture Exchange was created in Canada on November 29, 1999 as a result of an agreement among the Vancouver, Alberta, Toronto and Montreal exchanges to restructure the Canadian capital markets along the lines of market specialization.

The CDNX was created by the merger of the Vancouver Stock Exchange (VSE) and the Alberta Stock Exchange (ASE). The focus of the CDNX was junior companies, i.e., those whose assets, business and market capitalization were too small to be listed on the Toronto Stock Exchange (TSX). Often, these were resource exploration companies, but also came to include new high technology ventures. The exchange had its corporate headquarters in Calgary, Alberta, and its Operations headquarters in Vancouver, British Columbia, with additional offices in Toronto and Montreal.

Ian G. McClelland (born 22 June 1942, Trail, British Columbia) is an Edmonton-based businessperson, who was a member of the Canadian House of Commons from 1993 to 2000, and a member of the Alberta Legislative Assembly from 2001 to 2004.

Ian McClelland graduated from the Northern Alberta Institute of Technology in 1965, as a member of the first graduating class in Photographic Technology. In 1975, he started Colorfast Corporation, which grew under his management and ownership to become the largest independent photofinisher in Western Canada. At its peak, the company had twenty seven retail outlets, three manufacturing facilities and serviced five hundred retail outlets in Western Canada. McClelland sold the business to an employee, when he stood as a candidate in the 1993 federal election. In 1992, McClelland was honoured as a "Distinguished Friend of the Institute" by the Northern Alberta Institute of Technology.

McClelland was elected in the Edmonton Southwest electoral district under the Reform party in the 1993 and 1997 federal elections, thus serving in the 35th and 36th Canadian Parliaments. He served as a Deputy Speaker in the 36th Parliament, and was the first member of the Official Opposition to be so appointed. In 2000, McClelland announced that he would not seek a third term, and did not stand for re-election in the 2000 federal election.
