My colleague David Jones started a wiki in late 2008 that is intended to be a collegial site in which to share examples of how Canadians are using social media.
Although 57 organizations and consultancies have shared their work, the pace of uploading examples has eased. 'Doctor' Jones as he is known on Twitter has put out a call for Canadian social media professionals to reinvigorate their contributions. I think the wiki is worth reviving, so I am doing my small part to encourage you to do your part.
If all you want to do is review some of the work, take a look at the navigation bar on the left on the wiki.
