Great image of Montreal as well. The layering and different scale of the city always blows me away.

I don't know about better ecologically. It just is. This is going back to primary school science. Either my memory or the science I recall is no longer valid. However, native forests consisting of Edmonton's dynamic evergreens, birch, etc. are a more primitive stage in the evolution of forests compared to native hardwood forests consisting of Toronto's mighty maples and oaks. Health and welfare of the canopy is probably best with urban forest departments putting emphasis on planting native species over fast growing, dynamic or, pretty as they have did a generation ago.
