resource wanted - good book or online resource for trees (in Canada)?

Is there a good book or online resource for trees (in Canada)? I am looking for info like IDing trees, information on roots (deep vs shallow), requirements regarding light/moisture/etc. and ideally hardiness zone too.

If you are interested in native trees in your area try browsing through this site: Alberta Native Plant Council

Oh cool. Thanks!

I think it depends on where you are in Canada.  The trees that grow where I live on the West Coast, most of which won't grow a few miles inland.  A few more miles inland, and different trees again.

Do you have a local park or nature centre?  The people there could recommend a book for your location (then you can come back and tell us which book was right for where you are).  That's what we do when we move to a new city, check out the local parks, make friends with the staff, ask what books they use as a reference.

Alberta. Not sure if there is a specific book for our region. I was thinking some North American tree book or so. That hopefully has prairie tree also.
