Through a 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.
