The mountains of western Canada are dicey during the fall and summer, and certain areas can weather in for weeks at a time...
If you are going to fly in the fall (October/November) I would go anywhere in the Prairies. That's Alberta, Saskatchewan, or Manitoba. Sometimes cold, sometimes windy, but long stretches of clear skies and open airspace.
Check prices, and don't forget to add in the taxes... some provinces have Provincial Sales Tax on training, some don't.
