Alberta Health Services said Monday it is aware of at least four patients who are currently seeking access to a physician-assisted death.

The case of Ms. S., a Calgary woman granted a personal exemption allowing doctors to help her die, is raising questions about barriers to accessing physician-assisted death in Alberta after she travelled to B.C. to end her life.

A Calgary woman who received a legal exemption for doctor-assisted death has ended her life in Vancouver with the help of two physicians.
