The World Professional Association for Transgender Health - WPATH standards now state that a letter recommending hormone replacement therapy is suggested for a physician to begin treatment for transgender clients. In 2014 I participated in HRT Letter training with Rupert Raj in order to provide that service to individuals who feel that they are ready to transition. I can provide this service online as well so your location in Ontario or Nova Scotia is not a barrier to affirming support.
At least six sessions will be required to "meet" in order to prepare the letter. I then send the draft letter back to you for feedback prior to preparing it for you to share with your physician.
