...A link to [York University Library] Ejournal publishing support is prominently posted on the library's Services page for faculty. There is a whole page just on publishing using Open Journal Systems!.
YorkSpace is only one of York's 3 repositories, according to Leila Fernandez and Marcia Salmon, who also report that Canada is 4th among countries in societies publishing open access journals, in their presentation on Open Access Publishing.
Andrea Kosavic and Sharon Wong's Empowering Authors, a presentation for a Scholarly Communications Retreat at York, is well worth a look for some interesting approaches to explaining the key area of author rights to faculty.
The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
