MAiD was legalized in Canada in June of 2016, when the federal government passed the Medical Assistance in Dying (MAID) Act, which established the eligibility criteria and procedural safeguards for medically assisted suicide. In March 2021, new legislation was passed that expanded eligibility for MAID.
 

In the original legislation, a person had to have a terminal diagnosis, death had to be foreseeable, they had to have two witnesses. The 2021 legislation (Bill C-7) removed procedural safeguards so a person does not have to have a terminal diagnosis, death does not need to be foreseeable, only one witness is needed and it can be a medical professional.

MAiD is set to further expand in March 2027 for mental illness.
