In reply to Doug:
I don't think Dougherty’s book has been updated, just reprinted. It's known colloquially here as the "Book of Lies" and if you can find a copy, get more recent information from a source such as Summit Post, or one of the several Facebook groups.
Unfortunately there isn't one guidebook to rule them all, but I would recommend:
Northen Exposure - rock climbing in Jasper NP
Banff Rock by Chris Perry (you can download Bow Valley Rock for free, here: https://www.banffrock.ca/ )
11,000 of the Canadian Rockies
Search Gripped for new routes - here's one I recommend - https://gripped.com/routes/achilles-spire-is-a-big-5-8-rockies-route-you-sh...
Rogers Pass Alpine (not in the Rockies, but about an hour and a half West of Lake Louise), an amazing alpine climbing area on some excellent rock
Bugaboos - also not in the Rockies, but easily accessible from any of the Rockies climbing bases
