Posted this on the Canada Branch for you too, but pick up a copy of "Scrambles in the Canadian Rockies" by Alan Kane. It's about $20.

I live in Montana just South of the Canadian Rockies and I feel pretty confident in saying that you won't find aa lower snow pack than what is there this year. Trails should open really early. Check out Larch Valley between Morraine Lake and Lake Louise, Spectacular.

It would be a good idea to check the trail reports before you go to make sure the trails are not snowbound (or check with an information centre):
Banff
Yoho
Kootenay
Jasper
Kananaskis
(They show ski/snowshoe trails now, but will be updated with hiking trails in the spring.)

Bald Hills (Jasper) -- a great view of Maligne Lake, the Queen Elizabeth range, and the neighbouring valleys. Make sure you climb all the way to the top for the best views. You could wander around the top of the ridge for hours.
Wilcox Pass (Jasper) -- a nice view of the Athabasca Glacier
Emerald Triangle (Yoho) -- nice views of Emerald Lake.
Lake O'Hara (Yoho) -- top of my to-do list for this year. This one is limited access; the bus into the area can be booked in advance through Parks Canada. Check their website for details.
Sentinel Pass (Banff) -- Already mentioned for good reason. The Eiffel Lake trail branches off of the Sentinel Pass trail and is also very nice, as it provides views of the Wenkchemna Peaks most of the way along.
Burstall Pass (Kananaskis) -- Nice views into Banff NP. Crossing the flats may be very muddy/wet in June though.

Whistler is adjacent to Garibaldi Provincial Park which has lots of trails. I've only done Garibaldi lakes and black tusk (amazing) which has a trailhead between Whistler and Squamish, but there are trails from Whistler village.

Thanks very much for your advice guys, it really has been invaluable. Happy trekking everyone!

This is a great article on tripadvisor:

Overview HIKING GUIDEBOOKS Canadian Rockies (you probably can buy them all on Amazon)
The Best Day Hikes in the Canadian Rockies by Tim Jensen. Excellent reviews on this one. The book covers only the most rewarding day hikes throughout the Canadian Rockies, from short hikes to day long hikes. Clear descriptions and a detailed colour map for each hike. Great for each visitor of the Canadian Rockies.

The Canadian Rockies Trail Guide by Brian Patton and Bart Robinson. Many hikers regard this book as their "bible." If you want to buy only one book on hiking in the Canadian Rockies, you might consider investing in this one, which is now in its 8th edition and has been in print since 1971. You need to buy additional maps as the book does not contain detailed maps. The authors of the Canadian Rockies Trail Guide have also written 50 Walks and Hikes in Banff National Park, which is designed specifically for visitors to the park. It includes short walks, easy hikes, and day trips.

Don't Waste Your Time Hiking in the Canadian Rockies - An Opinionated Hiking Guide by Cathy and Craig Copeland. This book receives excellent reviews. Because of a few limitations (shortage of maps, for example), it needs to be used in conjunction with other resource materials.

Where Locals Hike in the Canadian Rockies by Cathy and Craig Copeland. Focuses on hikes within two hours of Calgary International Airport, primarily in Kananaskis Country.

Canmore and Kananaskis Country : Short Walks for Inquiring Minds by Gillean Daffern. It focuses on the shorter hikes (half-day or less) and has lots of nice notes on interpretation of history, plants, animals, and birds.

Hiking the Historic Crowsnest Pass by Jane Ross and William Tracy. The authors cover not only hikes but also the history of the places through which the trails pass. Because of the triumphs and disasters of its coal mines, this area has a rich and textured past.
