You will have to open an international trading account. This can be done through Nabtrade, Commsec and other big banks. Note that most retail investors trading platforms won't let you trade Canadian stocks (IG etc).
I strongly advise you to get in touch with your broker and assess the situation.
When trading on foreign stocks you have to factor in the conversion rates and the time difference : for example the Toronto Stock exchange opens in 14 hours (GMT-4), so you will have to trade at nightime.
