The TSX traces its informal beginnings back to the formation of an association of brokers by 12 Canadian businessmen in 1852. On 25 October 1861 the stock exchange was officially founded through the passage of a formal resolution at Toronto’s Masonic Hall. A total of 18 stocks could be traded. Trading in the early days consisted of half-hour sessions, which allowed for small numbers of trades.

In 1871 there were 14 firms that traded stocks on the exchange, having paid $250 each for the privilege, a so-called “seat.” By 1901 the price for a seat had risen to $12 000 and trading volume was close to one million shares per day. The increased popularity of stock trading caused the exchange to move to bigger offices. In total, the exchange moved five times over the course of its existence and today is located in the Exchange Tower at 130 King Street West in Toronto.
