Hi Fi,
British Columbia has snow.. lots of it!
Areas such as Bella Coola in the North of the Province have great snow from end of October – April but you can actually Heli- Hike/ Heli- Ski nearly all year round.

Whistler is extremely film friendly with the season starting mid November through until early April.
I’ve also attached some photographs from a town called Smithers, again in Northern BC when I was filming there in January 2011.
If you need any further information please get in touch, http://www.locationfixervancouver.ca
