Toronto Stock Exchange (TSX, formerly TSE) is the largest stock exchange in Canada, the third largest in North America and the seventh largest in the world by market capitalization. Based in Canada's largest city, Toronto, it is owned by and operated as a subsidiary of the TMX Group for the trading of senior equities. A broad range of businesses from Canada, the United States, Europe, and other countries are represented on the exchange. In addition to conventional securities, the exchange lists various exchange-traded funds, split share corporations, income trusts and investment funds. The Toronto Stock Exchange is the leader in the mining and oil & gas sector; more mining and oil & gas companies are listed on Toronto Stock Exchange than any other exchange in the world.

The Toronto Stock Exchange likely descended from the Association of Brokers, a group formed by Toronto businessmen on July 26, 1852. No official records of the group's transactions have survived. On October 25, 1861, twenty-four men gathered at the Masonic Hall to officially create the Toronto Stock Exchange. The exchange was formally incorporated by an act of the Legislative Assembly of Ontario in 1878.

Toronto (/təˈrɒntoʊ/, colloquially /ˈtrɒnoʊ/) is the largest city in Canada and the provincial capital of Ontario. It is located in Southern Ontario on the northwestern shore of Lake Ontario. A relatively modern city, Toronto's history dates back to the late-18th century, when its land was first purchased by the British monarchy from the Mississaugas of the New Credit. The settlement was later established as the Town of York and proclaimed as the new capital of Upper Canada by its lieutenant-governor, John Graves Simcoe. In 1834, York was incorporated as a city and renamed to its present name. The city was ransacked in the Battle of York during the War of 1812 and damaged in two great fires in 1849 and in 1904. Since its incorporation, Toronto has repeatedly expanded its borders through amalgamation with surrounding municipalities, most recently in 1998.

With over 2.6 million residents, it is the fifth most populous city in North America. Its metropolitan area has over 5.5 million residents. Toronto is at the heart of the Greater Toronto Area (GTA), and is part of a densely populated region in Southern Ontario known as the Golden Horseshoe, which has a population of nearly 9 million people as of 2011. The census metropolitan area (CMA) had a population of 5,583,064, and the Greater Toronto Area had a population of 6,054,191 in the 2011 Census. Its cosmopolitan and international population reflects its role as an important destination for immigrants to Canada. Toronto is one of the world's most diverse cities by percentage of non-native-born residents, with about 49% of the population born outside Canada. Toronto is also consistently rated as one of the world's most livable cities by the Economist Intelligence Unit and the Mercer Quality of Living Survey.

A stock exchange is a form of exchange which provides services for stock brokers and traders to trade stocks, bonds, and other securities. Stock exchanges also provide facilities for issue and redemption of securities and other financial instruments, and capital events including the payment of income and dividends. Securities traded on a stock exchange include shares issued by companies, unit trusts, derivatives, pooled investment products and bonds.

To be able to trade a security on a certain stock exchange, it must be listed there. Usually, there is a central location at least for record keeping, but trade is increasingly less linked to such a physical place, as modern markets are electronic networks, which gives them advantages of increased speed and reduced cost of transactions. Trade on an exchange is by members only.

The initial offering of stocks and bonds to investors is by definition done in the primary market and subsequent trading is done in the secondary market. A stock exchange is often the most important component of a stock market. Supply and demand in stock markets are driven by various factors that, as in all free markets, affect the price of stocks (see stock valuation).
