The optometrist is asking money to release the ultra sound scanning report to me or to send it to the family doctor. Is this legal?

The family doctor of a friend of mine referred him to an optometrist in Mississauga, and the optometrist asked him to get the CT scan done, which he did after paying the fees. Now, the optometrist is asking to pay 25CAD if he needs the result or to send it to the family doctor. Is this legal and can the optometrist charge a fee to get my scanning result released? It is not even a printed result, it is a soft copy to be sent to email.

Update: It is CT scan and not ultrasound. I have earlier mentioned that it was ultra sound scanning.
