The east coast isn't in yet this year, it's been too warm. It should be good in another couple weeks, hopefully. it's great when it's in though. Highly recommended!
yes, you could climb lines similar to PC every day up in Canada, pending the avy forecast. PC is a long route, but there are tons of other things that are 300m or more. Get "Waterfall Ice" by Joe Josephson...
if you're looking to go cheaply, Cody or Hyalite are easier places to camp (even though the nights can be mighty cold). The RCMPs don't seem to like it when I bivy out on the Icefields Parkway.
