Can I complain about a doctor online?

I had an absolutely terrible incident with a homophobic doctor. I have taken all the steps to report him to the local College of Physicians and Surgeons, and I hope he gets disciplined, but that doesn't address the systemic problem of homophobia in family physicians in my area (and it doesn't help me find a less homophobic doctor to switch to). I would like to blog about the incident, contact gay and lesbian associations, etc, but I am worried about being sued for libel/slander/I don't know. Will I get in trouble if I write publicly about this incident? Can I use the Dr's name? I'm in Alberta, Canada.
