Statistics Canada (and similar bodies in other countries) is a great source for consumer demographics. You can see the population, income, family size, and other details for various locations. The video below will show you how to search and navigate StatCan data. As an example, look at the StatCan data for Nanaimo.

Some cities produce Community Profiles, which often add some useful local context to StatCan data. Check out Nanaimo's 2021 Community Profile as an example. Search for these using Google with search terms like: "community profile" victoria
