Hetty, most TSX stocks trade in the US on the Pink Sheets with a different symbol and in US Dollars. Your broker can get you the symbol and the bid and asked prices. You can then trade them yourself at a low commission using your computer. Schwab and Fidelity encourage you to get a quote and trade yourself.
