The Digital Research Alliance of Canada (formerly Compute Canada) manages national HPC clusters running customized Slurm workload manager configurations and contributes open-source tooling for scientific computing. Their open-source stack powers university research across the country.

The National Research Council of Canada (NRC) publishes numerous open-source tools and datasets for materials science, climate modelling, construction standards, and aerospace research. Their open-data and open-software initiatives are publicly available via the Government of Canada's open resource portal.

Statistics Canada releases open-source tools and R/Python packages for statistical analysis and data dissemination. Their tools include the Canadian Statistical Dissemination Architecture (CSDA), open microdata tools, and visualization packages used by researchers across Canada.

Developed by the National Research Council of Canada, the NRC Word-Emotion Association Lexicon (EmoLex) is a widely-cited open linguistic resource mapping words to emotions and sentiments. It is freely available for research and has been used in thousands of NLP studies worldwide.

Aries Verifiable Credentials Registry (VCR), part of the Hyperledger Aries family of Digital Trust technologies, provides a searchable public directory based on Verifiable Credentials (VCs). It was historically known as both OrgBook (which is actually a deployment of Aries VCR) and Indy Catalyst. Aries VCR is actively developed by the British Columbia Government’s Digital Trust Team in Canada, and the most well-known live example is OrgBook BC. In an instance of Aries VCR, credentials can be issued from a variety of authorities about subjects in the instance. A core set of credentials are issued by an authority responsible for “creating” the subject. Other credentials can then be issued against the subject of these core credentials. All credentials are stored in a secure digital wallet and accessed via its website or the public API. This means an instance of Aries VCR can be an authoritative public registry of any referenceable information.
