From the Press Release:
. . . . Under this new Policy, which will apply to all grants awarded after January 1, 2008 that receive funding in whole or in part from CIHR, grant recipients must make every effort to ensure that their peer-reviewed research articles are freely available as soon as possible after publication. This can be achieved by depositing the article in an archive, such as PubMed Central or an institutional repository, and/or by publishing results in an open access journal. A growing number of journals already meet these requirements and CIHR-funded researchers are encouraged to consider publishing in these journals.
Additionally, grant 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. . . .
From the official policy on Access to CIHR-funded Research Outputs:
5.1.1 Peer-reviewed Journal Publications
Grant recipients are now required to make every effort to ensure that their peer-reviewed publications are freely accessible through the Publisher's website (Option #1) or an online repository as soon as possible and in any event within six months of publication (Option #2).
Under the second option, grant recipients must archive the final peer-reviewed full-text manuscripts immediately upon publication in a digital archive, such as PubMed Central or the grantees institutional repository. Publications must be freely accessible within six months of publication, where allowable and in accordance with publisher policies. Grant recipients may use the SHERPA/RoMEO database to locate summaries of publisher copyright policies. The SHERPA/RoMEO database will help grant recipients determine which journals allow authors to retain copyright and/or allow authors to archive journal publications in accordance with funding agency policies. However, CIHR recommends confirming with editorial staff whether archiving the postprint immediately, and making it freely accessible within six months, is permissible.
