From the London Mail [caution, tabloid]:
An elderly woman was euthanized within hours of her husband claiming she changed her mind after insisting she wanted to live. Canada‘s Medical Assistance in Dying laws allow patients to request a painless death if an assessor agrees their terminal condition meets certain requirements.
Patients often wait weeks, but it can happen the same day the application is lodged if judged to be medically urgent by a MAiD provider. However, she told the assessor she ‘wanted to withdraw her request, citing personal and religious values and beliefs’ and instead wanted inpatient hospice care.
