It's funny that people think voting changes things like this, especially when the issue in question is something that was drafted up by a room full of lawyers and lobbyists.
The roomful of lawyers and lobbyists aren't the ones who get to pass the law. If you're Canadian then you likely know that a Harper/Conservative majority would love to ram this stuff through, whereas the other parties aren't so inclined. Given that we've had minority governments (a foreign concept to Americans) for the last three elections, a few votes can actually sway things quite a bit in this election.
