The Toronto Stock Exchange is commonly known as the TSX. The TSX is operated by TMX Group Limited, which also operates a number of other exchanges, including the TSX Venture Exchange (TSXV). The TSXV is recognized as the primary Canadian market for junior issuers, while the TSX is regarded as the primary Canadian market for senior issuers, together representing significant international markets in terms of capital raised and number of listed companies.

For the most part, the TSX does not recognize the difference between primary and secondary listings, and little distinction is drawn between foreign and domestic companies in terms of initial listing requirements. However, it is expected that prospective issuers with properties or business in certain emerging markets will face additional scrutiny as the TSX has issued additional guidance for the review of applications by emerging market issuers.

TSX applicants are divided among three listing sectors: diversified, mining, and oil and gas. The listing categories are set out as follows:

• Diversified companies.
  • Income & revenue-producing companies.
  • Pre-income-producing companies.
  • New enterprise companies.
• Mining companies.
  • Producing mining companies.
  • Mineral exploration and development-stage companies.
  • Senior mining companies.
• Oil and gas.
  • Oil and gas companies.
  • Senior oil and gas companies.

The total market capitalization of the TSX was approximately C$6.29 trillion (approximately US$4.58 trillion) as of 31 December 2025, representing an approximate 28% increase since 31 December 2024 when the market capitalization of the TSX was approximately C$4.91 trillion (approximately US$3.58 trillion).

The TSX and TSXV are global leaders in listing issuers in the resource sectors, including mining and oil and gas companies. As of 31 December 2024, approximately 40% of the world's public mining companies were listed on the TSX and TSXV, and approximately 47% of the world's mining financings in the five years prior thereto were completed by companies listed on the TSX and TSXV. Approximately 18% of all global public oil and gas companies are listed on the TSX and TSXV. The TSX and TSXV also list a growing number of technology and innovation companies (including those in the technology and life sciences sectors).

As of 31 December 2025, there were 2,089 companies listed on the TSX. Of these, 83 companies were foreign-based, representing approximately 4% of all TSX issuers.

In Canada, securities regulation is achieved through a combination of regulation by securities regulators, self-regulatory organizations and exchange level supervision. In the case of most public securities matters, there are issues to be addressed at each level. However, in terms of listing requirements, the TSX sets its own standards. In any case, while neither the applicable provincial or territorial securities commission nor the Canadian Investment Regulatory Organization is directly involved in the application process, these organizations impose restrictions on many other aspects of the securities regulation process.
