Complete geographic keys for census spatial units

A key dataset linking Dissemination Areas (DAs) to some higher-level geographic units used in the 2021 Census of Population. This dataset provides the hierarchical relationships between DAs, Census Tracts (CTs), Census Subdivisions (CSDs), Census Divisions (CDs), Census Metropolitan Areas (CMAs), and Provinces (PRs). It is created based on the Statistics Canada's geographic reference files.
