Each Census cycle, a great number of statistics are produced and disseminated by Statistics Canada in census profiles and various data tables. In addition, many custom tabulations are created based upon requests sent to Statistics Canada Head Office as well as those submitted in the Research Data Centres. For the 2021 Census, the system currently used to produce these estimations, the Computer-assisted Product Specification System (CAPPS), will be replaced by the Statistics Canada Generalized Tabulation Tool (GTAB). From a methodological viewpoint, this transition brings its share of challenges, as well as opportunities to improve the quality of disseminated data while continuing to protect the confidentiality of respondents. These challenges and opportunities will be further explored throughout the presentation.
