Reference Data as a Service (RDaaS) API

The Reference Data as a Service (RDaaS) API provides a list of codesets, classifications, and concordances that are used within Statistics Canada. These resources are shared to help harmonize data, enabling better interdepartmental data integration and analysis.

This dataset provides an updated version of the StatCan RDaaS API specification, originally part of the Government of Canada’s GC API Store, which permanently closed on September 29th, 2023. The archived version of the original API specification can be accessed via the Wayback Machine .

The specification has been updated to the OpenAPI 3.0 (Swagger 3) standard, enabling use of current tools and features for API exploration and integration. Key interactive features of the updated specification include:

  • Try-It-Out Functionality: Allows a user to interact with API endpoints directly from the documentation in their browser, submitting test requests and viewing live responses.
  • Interactive Parameter Input: Simplifies experimentation with filters and parameters to explore API behavior.
  • Schema Visualization: Provides clear representations of request and response structures.
