Lately there has been a fair bit of regulatory discussion about social media.  However other than some general commentary under NI 31-325, the industry has received very little official guidance.  Folks who are interested in learning more about best practices in this area (and probably where the Canadian regulators may get inspiration when they publish guidance) may wish to take a look at a document from the SEC summarizing their findings and recommendations from reviews of Investment Advisors that use social media.  http://www.sec.gov/about/offices/ocie/riskalert-socialmedia.pdf.  It’s an interesting read on compliance challenges arising from the use of social media.
