The Michael Smith Foundation for Health Research, which is funded by the Government of British Columbia, adopted an "Open Access to Research Outputs Policy" on July 6, 2009. (Thanks to Be Openly Accessible or Be Obscure.)
Here's an excerpt:
All MSFHR Award Recipients who receive an award or an award renewal after July 7, 2009 must ensure that all final peer-reviewed journal manuscripts that arise from research supported by that award (in whole or in part) are made freely accessible through either the Publisher's website or an online repository within six months of publication.
The Policy applies to any manuscript that is supported from funding in whole or in part from a MSFHR Award. The manuscript must be peer-reviewed and is accepted for publication in a journal on or after July 7, 2009. This includes all graphics and supplemental materials that are associated with the article. The Policy does not apply to non-peer-reviewed materials such as book chapters, reports, monographs, conference proceedings and editorials.
Additionally, Award Recipients are now required to deposit bioinformatics, atomic, and molecular coordinate data, as already required by most journals, into the appropriate public database immediately upon publication of research results.
Authors are encouraged, but are not required, to submit final peer-reviewed manuscripts accepted before July 7, 2009, if they have appropriate copyright permission. MSFHR Award Recipients are responsible for ensuring that any publishing agreements concerning submitted manuscripts fully comply with this Policy.
