Step One
Obtain a donor consent form from the school of anatomy of your choice. One copy will be kept with the school, and one will be kept by you.
Step Two
Talk to your family and executor, and make them aware of your wishes.
Step Three
Make note in your will:
“Upon my death, I direct that my body, if acceptable and needed for anatomical studies and medical research, be delivered to the Division of Anatomy at the University of Toronto (or to the nearest Medical School).”
