Alberta Stock Exchange
In 1999 the Alberta Stock Exchange merged with the Vancouver Stock Exchange to form the Canadian Venture Exchange (CDNX) handling trading in junior equities. The Canadian Dealing Network, Winnipeg Stock Exchange, and the equities portion of the Montreal Exchange later merged with CDNX.
In 2001, the CDNX was acquired and rebranded as TSX Venture Exchange by the Toronto Stock Exchange, which itself was rebranded as the TSX Group Inc. In December 2007, TSX Group merged with Montréal Exchange Inc. to form TMX Group Inc.
The Alberta Stock Exchange was incorporated on October 25, 1913 by an act of the Province of Alberta and began operations in 1914 . Edmund Taylor was the first president of the exchange, which has been the principal petroleum industry exchange in Canada. From 1917 to 1925 operations ceased, partly as a result of the war. From 1926 to 1975 it operated as Calgary Stock Exchange.
