Finding demographic and geographic data is easy through the Government of Canada census data. Data is often available for key demographic and geographic questions, like how many people live in an area, or how many people are within a certain age range, income category, career area, etc.
Census data is gathered by Statistics Canada every five years and made available through various data tables. This is the main source for population counts in Canada.
The following video does a great job showing you how to find census data and use it for determining your market size and getting demographic information.
