Website and Data Usage Policies


The Canadian VirusSeq Data Portal (CVDP, also referred to as "the Portal") is an open-access data portal intended to facilitate access to Canadian SARS-CoV-2 sequences and associated non-sensitive metadata adhering to the FAIR Data principles. The Portal will manage and share limited contextual metadata and viral genome sequences among Canadian public health labs, researchers and other groups interested in accessing the data for surveillance, research, and innovation purposes. In doing so, it will complement the controlled-access platform developed by the National Microbiology Laboratory (NML).

The Portal will harmonize, validate, and automate submission to international databases and enable the creation of real-time dashboards that summarize the Canadian data contributions while facilitating exploration and access. The Data Portal is funded by Genome Canada.

The CVDP is not providing access to any personal data at the current time. If you are submitting sequences or metadata to the CVDP, do not include any data that could reveal the personal identity of the source.


COVID-19 is an emerging and rapidly evolving situation. To promote responsive, collaborative, research and public health surveillance, virus sequences and minimal metadata are released on the CVDP rapidly and should be considered draft and subject to change.

Beyond limited editorial and quality controls and some internal integrity checks, the quality and accuracy of the record are the responsibility of submitters, not of the CVDP. It is also the responsibility of submitters to ascertain that they have the right to submit the data. The CVDP team will work with submitters to provide feedback on metadata and sequence data to improve the overall quality and consistency of the data submitted.

Data users guidelines

Access to the data provided within the CVDP is provided in a completely open manner, and at no cost to members of the scientific community and other interested parties. Nevertheless, users are expected to follow the CVDP policy on Recognition of the work of data submitters. Users should not attempt to make use of the portal data to attempt to re-identify specific individuals. In the unlikely case you come across identifying data, please swiftly report the event, indicating the problematic dataset, at

Data standards guidelines

As data needs change over time, the data standard implemented by the Data Portal evolves (additional fields and terms may be added, requirements may be updated, etc). This may alter the database schema as well as the types of information provided by data stewards. For more information, please contact Dr. Emma Griffiths at

Recognition of the work of the data submitters

You may use the data from the CVDP to author results obtained from your analyses of relevant data, provided that your published results acknowledge, as the original source of the data, VirusSeq, CPLHN and its members.

Proposed sentence: “The authors of the manuscript would like to acknowledge the original source of the data VirusSeq, CPLHN and its members.”

Please note that the data that is being shared is the work of many individuals and should be treated as unpublished data. If you wish to publish research using the data, contact us at first to ensure that those who have generated the data can be involved in its analysis. You are responsible for making the best efforts to collaborate with representatives of the Originating Laboratory responsible for obtaining the specimen(s) and involve them in such analyses and further research using such Data.
