Reports are coming in from across Canada of voters receiving pre-marked ballots favouring Conservative and Green candidates. It could be a printing error that only coincidentally favours the Conservatives and the party that is not in contention, but the given the Cons history of corruption and election fraud, I am concerned. If you receive a ballot like this be sure to request a new one.
