Grant recipients are required to ensure that any peer-reviewed journal publications arising from Agency-supported research are freely accessible within 12 months of publication. Recipients can do this through one of the following routes:
NSERC & SSHRC: This policy applies to all grants awarded May 1, 2015 and onward.
CIHR: This policy applies to all grants awarded January 1, 2008 and onward. CIHR grant recipients have additional responsibilities to make their research data publicly available.
If you have research funding from another source it is possible that your funder has an open access policy. Sherpa Juliet is a global database of funder's OA policies, and is a great way to quickly look up the details of the policy and how you comply.
