Final answer:
The Toronto Stock Exchange (TSX) is Canada's main stock exchange similar to the NYSE, whereas Chi-X Canada (Chi-X) is an ATS that allows electronic trading of securities without a physical floor.
Step-by-step explanation:
The Toronto Stock Exchange (TSX) is Canada's primary securities exchange where stocks are traded, acting similarly to the New York Stock Exchange (NYSE) in the United States. Unlike the TSX, Chi-X Canada (Chi-X) is an alternative trading system (ATS) that provides a venue for trading securities outside of traditional stock exchanges, offering a platform for trade execution that does not have a physical trading floor like the NYSE or TSX. Similar to how the Nasdaq operates without a physical trading floor and provides electronic trading, Chi-X Canada also enables transactions to happen electronically. Both the TSX and Chi-X facilitate the trading of securities, but they operate differently and cater to different types of investors and market participants.
