If I had to guess I'd say those are maples might be Fall Fiesta Sugar Maples but idk for sure. As far as the columnar aspens go they're nice enough but the problem with a lot of those columnar varieties is that although they grow quickly and are space efficient, they also die fairly young as well.
Personally I wish that cities in Alberta would plant more heritage trees that although slow growing will someday create a really great and diverse urban forest. I wish I saw more oak, maples and even walnuts trees in Alberta. Unfortunately a lot of new communities avoid large slow growing trees due to small/non-existent front yards and a desire to plant fast growing trees.
