REALTOR.ca

REALTOR.ca is the national residential property listing portal of the Canadian Real Estate Association (CREA), the cooperative trade association representing roughly 160,000 REALTORS® across some 60 member boards and associations in Canada. Unlike the United States, where roughly 500 independent MLSs each run their own data pipe, Canadian listing distribution is consolidated through CREA's REALTOR.ca Data Distribution Facility (DDF®), a single national syndication service that normalizes MLS® System data from member boards and republishes it to member websites, franchisor sites, real estate advertising websites and technology providers. CREA sits squarely in the middle of the Canadian value chain — it owns the consumer portal, the national listing pool, and the syndication rails that every downstream site depends on. Its API posture is real but closed: the DDF® Web API is a genuine OData surface at https://ddfapi.realtor.ca/odata/v1 with public, browsable documentation and a downloadable OpenAPI 3.0.4 description, yet every endpoint (including the OData $metadata document) returns 401 without a Bearer token, and tokens are only issued via client_credentials against identity.crea.ca using data-feed credentials that a REALTOR® or broker owner must first create and link in the member portal. CREA is a RESO member and states its data is normalized to the RESO Data Dictionary, but no CREA entry could be confirmed in the RESO certification directory, so this profile records the DDF® Web API as RESO-aligned rather than RESO-certified. There is no self-serve developer signup, no sandbox, no open data product, and no public consumer search API for realtor.ca itself.

REALTOR.ca publishes 2 APIs on the APIs.io network: DDF Web API and DDF Lead API. Tagged areas include Real Estate, Canada, Property Listings, MLS, and RESO.

REALTOR.ca’s developer surface includes documentation, API reference, getting-started guide, legal docs, support, engineering blog, changelog, and 30 more developer resources.
