Hi Mailman,
While not a civi-flier at all - all my time is military - I do fly in the rocks daily and see the operators.
If you want to live near a snow capped mountain and fly - you'll want to live in BC or Alberta.
I suggest you check out avcanada.ca for the ins/outs of working for the civi operators out here.
Point your search engine towards:
1) Pacific Coastal Airways
2) Central Mountain Airways
3) Jazz (Air Canada regional service)
If you have any float time I would suggest Harbour Air - based out of Victoria, BC.
