The Montreal Curb Market was a stock exchange created in 1926 in Montreal, Canada for trading in stocks that were considered to be too speculative or junior to be traded on the Bourse de Montréal. As these companies matured, trading in their shares was transferred to the Bourse.
In 1953, the Montreal Curb Market changed its name to Canadian Stock Exchange.
In 1974, the Canadian Stock Exchange merged with the Bourse de Montréal, under the larger exchange’s name.
