I have written, many times over the years, about small-scale commercial uses in residential neighborhoods. Here in Toronto, they are generally not permitted. The small convenience stores and bodegas that remain are often legal non-conforming uses.
Today I came across a great example from Calgary. I don't know if it was done on an as-of-right basis or if variances were needed, but it is an example of small-scale commercial on a site that used to be low-rise residential.

Developed by RNDSQR and designed by FAAS Architecture, the project houses three street front commercial units that are now leased -- according to their website -- to an ice cream shop, a coffee shop, and a pizza + wine bar. The second flour houses office space.
Congratulations to the team behind this development. It looks like a terrific project. And in my view, being able to leave your home and walk to things is one of the greatest urban amenities out there.
