I don't know the laws in Canada. But even here in the USA where you do have the right to your records, it doesn't cover the doctor's personal notes etc. What records you do have a right to here are appointment comments of whether you arrived or not, what your diagnosis is, your ( or the insurance company)payments, your history which you gave them in the first place, etc.

I personally do NOT think it is a good thing for any mentally (or physically) unwell person to read their files, even if they were open to them. I'm sure the reasoning is the same as to why we do not have access to everything the doctor notates

Be well.
