I have scrambled and/or climbed most all the mountains in Kane's book and compiled much of my first hand beta here on SP. If you Googled scrambles in the Canadian Rockies, it is kind of hard to miss at the top of your search as it is frequently used. http://www.summitpost.org/canadian-rockies-scrambles/363160
This index list is broken down into areas/parks and is in order of east to west. Like Kane, I used an assessment of east-moderate-difficult. I also supply a suggested gear call for each and evey routes as well as time of year to climb. What Kane does not supply is a list of favorites, which like many guidebooks, I have done here via *** system. The index page shows those ***, thus you can quickly hone into an area and then favorites without having to click through each page.
If you want to step it up to potential roped climbing, then use this link to access my first hand account of most of the alpine climbs within your range. Again, any time you just google alpine climbs in the Canadian Rockies, it will be first and foremost, often used, so easy to find without having to remember the link. Same system in terms of east to west and favorites on the index page.http://www.summitpost.org/canadian-rockies-alpine-climbs/371653
Enjoy your visit. Typically expect plenty of snow lingering for this time of year at higher elevations. Good Luck!
