I'm also in Canada and if you know of someone you want to be referred to, write down all their contact info, take it into your GP and ask for a referral. They rarely deny you unless you are way off base with your choice based on the symptoms.

I am waiting to go to the brain injury rehab clinic in july, so I have no idea if they are good or not, but every major center will have one. (Ottawa, Montreal, Toronto, etc)

My GP didn't even KNOW we had a brain injury rehab clinic in our city. I happened to google search my city and brain injury and found info on their website about it.

I actually called the clinic first and discussed my symptoms and whether or not they were the sort of thing they dealt with and the intake nurse said definitely and gave me all the info to give to my doc.

When I presented it to my doc, he was not all that keen at first, but I told him that I would like them to do an assessment and then if they had anything to offer me, great, if they said I did not have pcs / tbi then I would learn to live with my symptoms (or take the antidepressants my doc keeps pushing!) and get on with my life. That seemed to sell it for him.

Best of luck.
