This whole thread is about being able to buy things in Canada. So the same benefits as anything else you would buy here instead of importing from another country. Pricing I am not sure of, but quicker shipping times, cheaper shipping, no duties (obviously something will be included in the cost, but prob less than if you imported it yourself). Also if you have a problem, you're dealing with someone in Canada and things can be rectified cheaper and faster. Also, it looks like Nafta will be going away, so its going to get more expensive to move things over the border.
You're obviously an intelligent guy, I don't really see why I would need to spell this stuff out
