History of TMX Group

TMX Group originated from the Toronto Stock Exchange (TSX), founded in 1861 that initially listed 18 stocks. By the end of the 1990s, TSX was the national exchange for senior equities. Its counterpart in Quebec, the Montreal Exchange (MX), handled trading in derivatives. Other exchanges in Vancouver, Calgary, and Winnipeg merged to form the Canadian Venture Exchange (CDNX), which traded junior equities.

TSX was registered as a for-profit enterprise in 1999, making it eligible to be a publicly traded stock. In the early 2000s, TSX assumed ownership of the Canadian Venture Exchange (CDNX) and renamed it the TSX Venture Exchange. TSX officially changed its name to the TMX Group in June 2008.

TMX acquired Trayport, a London-based energy-trading platform, from the Intercontinental Exchange (ICE) in 2017. This allowed TMX to access global utility, energy, and derivatives markets and satisfied the British government’s interests in a diversified marketplace for trading software.In 2021, TMX Group acquired AST Investor Services Inc. and its subsidiary AST Trust Company in Canada, a provider of transfer agency, corporate trust, and related services to Canadian public and private companies.


In 2021, the Toronto Stock Exchange listed the world’s first Bitcoin ETF.
