I haven't seen this on here yet, the powers that be most likely don't give a hoot anyway but signing this petition to the government of Canada is better than doing nothing. Writing a letter to your local MP is even better.
Edit: I should clarify, this is a petition to "call upon the Government of Canada to put any new firearms laws, bans, buyback programs or changes to licencing before the House of Commons to be debated."
