Statistics Canada produces statistics that help Canadians better understand their country—its population, resources, economy, society and culture. In addition to conducting a Census every five years, there are about 350 active surveys on virtually all aspects of Canadian life.
You can find data about your city in the Census - type in your city. For example, Montreal. If you are looking at a specific cultural group in Montreal, such as the Haitian community, you can search the profile table and use the control-F feature on your computer to search for mentions of Haiti. You can view the number of community members who speak Haitian Creole as their mother tongue, number of Haitian immigrants, population by ethnic origin, etc.
The Canadian Community Health Survey gathers health-related data at the sub-provincial levels of geography (health region or combined health regions).
Statistics Canada provides data about immigration and ethnocultural diversity, including data from the 2022 Census on immigrants, second-generation Canadians, and visible minorities.
If you are looking for information about Aboriginal Peoples in Canada, Statistics Canada maintains Statistics on Indigenous Peoples. The Health and Well-Being section contains data on topics such as food security and eating habits. The Indigenous Population Profiles are available for selected cities and communities.
There are also potentially a number of thematic reports produced by Statistics Canada related to specific communities - for example, Changes in the socioeconomic situation of Canada’s Black population, 2001 to 2016 includes some useful information about the Haitian community in Canada. These can usually be found by searching the Statistics Canada site.
