The problem isn't that it's a bad sample size per se. Given Canada's population (~37M), you get something between 2-3% margin of error at 95% confidence level with that sample size. The problem comes down to how you get your samples — online polling especially is skewed by how you pick your audience. For example, if you only poll your friends, your friend's friends and so forth until you hit the number, you will likely see a pretty uniform result, which is obviously far from giving any reasonable insight.
