I've checked all carriers that are listed in the ITA Matrix 2. This includes Westjet and Porter. (Southwest & co do not fly to YHZ anyway.)
And, yes, I've checked one season ahead - every day up until October 2011 (you can't check any further). For a big number of destinations in Canada, the US and selected Carribean destinations. It was always cheaper up until Dec 15. OK, then it's XMas-season - but afterwards the prices don't drop back to the level of the upcoming five weeks.
