If you are a Canadian, get out there and bloody vote!!!
With very few exceptions, there is nothing you will do today that is more important.
I don't care if you follow politics religiously and know who you'll vote for, follow it and still have no clue or don't even know who is running and have to throw darts to decide. GO VOTE!!!!!
Even an uninformed random vote tells the politicians that we are watching them and makes them less likely to screw around. When you don't vote, you tell them you don't care what they do at all - can you afford to send that message?
If you have never voted before and have no clue who is running and can't choose then toss a freaking coin. Getting involved in the first step. Chances are next time you'll know a little more and the time after that even more.
