The December 2015 workshop (CCC 'Let's Talk Geocaching' Workshop - Dec 2015 by Canada's Capital Cachers, http://coord.info/GC677KX
) will talk about Winter Caching Tips & Tricks.
A good way to familiarize yourselves with the fun and realities of Canadian winters.
If you read the latest Groundspeak geocaching blog about Winter Geocaching (http://www.geocaching.com/blog/2015/12/winter-geocaching/
), make sure that you do NOT follow their advice to "bring a poking stick and poke that snow till you hear a clang or thud"... that would be the best way to damage a container already made brittle by the challenging conditions of cold weather. The CO will thank you for it.
