First thing to do is educate yourself. You need to know what the different types of funds are, and what types of instruments you might own.
I don't know what the rules are in Canada, in the USA one of the things you need to avoid is churn. A broker can generate more money for themselves by having you buy and sell more often than is absolutely necessary. Every trade costs you money, and makes money for the broker. I had a fund for my son's college money that made zero dollars over a five year period (on a 4k investment, so it's not like it broke me or anything) because I gave him permission to trade as he saw fit and he burned up all of my gains in trading fees.
Energy stocks or energy-heavy mutual funds should be a good bet for the next few years, as Dood said. I think any resource based stuff, especially Canadian resources, should be good for you.
For a younger person, at least down here, I would be buying real estate like it was candy. Prices are so depressed that if you can afford to hold it for a while I think it just HAS to make money.
