Winter arrived early to Canada this year. Edmonton was getting snowfalls by early October and now in November, Ontario and Quebec were getting 20cm along the Saint Laurent river. Anyways, winter arrived early and there are no chances it goes away until March.
Regularly, it was used to be from Dec 1st to Apr 1st, but it is now officially on since Nov 13th. Short post, but just to give a heads up to my fellow Montrealers ;)
