May 2025 Release of the Canadian Edition of SNOMED CT now available!

The May 2025 Canadian Edition (CA Edition) is harmonized with the SNOMED International May 01, 2025, monthly release. Content includes immunization/vaccine concepts, new French translations, and new concepts requested by Canadian stakeholders to support diverse implementation projects across the country. For the first time, the SNOMED CT Canadian Edition also includes new drug-related content to support the Canadian Medicines Terminology (CMT) project.

New concepts and descriptions have been created in this CA Edition to support Canadian implementations, including: ongoing immunization work; the Canadian Institute for Health Information (CIHI) pan-Canadian Health Data Content Framework (pCHDCF) and Canadian Core Data for Interoperability (CACDI); updates to the organism hierarchy to support provincial Laboratory Information Systems (LIS),  other projects from Ministère de la Santé et des Services sociaux du Québec (MSSS) such as CNESST, CISSSMO, and PTI.

Infoway also releases updated versions of SNOMED CT valuesets as part of the CA Edition. The May 2025 CA Edition of SNOMED CT and all pan-Canadian valuesets are available on the Infoway Terminology Server. 

Release notes for the CA Edition are available here, along with general editorial guidelines and guidelines for making change requests in the Canadian context.
