In the US a sole proprietorship is different than an LLC. It's basically just an alias that an individual uses to operate as a business. I think this is the same in Canada. An LLC limits your liability in the case that the business goes bankrupt or someone sues you or something like that so that your personal assets can't be taken.

I'm hesitant to give legal advice, especially to someone in another country whose laws I don't know, but in the US sole proprietorship are very common for small businesses and you can always switch to an LLC (or its Canadian equivalent) later.
