You cannot do this in Quebec, where self-administered MAID is not legal. It is allowed, however, in the rest of Canada.
In Quebec, in the event of a serious illness, you can request and receive MAID with complete peace of mind if you meet the legal criteria. It will be administered by a physician.
In Canada, outside of Quebec, a physician or nurse practitioner can administer MAID to you. A physician can also prescribe medication that you would take in front of him or her.
