I'm in Ottawa and had my neuro psych assessment done about 14 months after my injury.

My physiatrist (rehab doc) at the rehab center here arranged for one through the inpatient program even though I'm an outpatient. I was very lucky as that almost never happens. That meant mine was covered through ohip. Normally, yes they do cost around $4000, at least that was what I was quoted.

Ask your docs at the brain clinic about it. They will probably be happy to refer you. If you have extended health plan benefits through work or your husbands work you may be able to claim at least part of the expense that way.

Make sure you go to someone well respected in the area. I know there are a couple in my area that my rehab doc warned me not to see when I was originally going to do it outside the rehab center. He said they primarily do the assessments for the car insurance companies and aren't necessarily great for people looking for actual information. For people looking for lawsuit paperwork they are fine.

Good luck.
