The six-part one-hour drama shoots in and around Toronto through the summer and is set to premiere on Global in Canada in early 2024.

Set in the morally grey world of assisted suicide, Mary Kills People is an intense, controversial, and thought-provoking drama.  The series follows Dr. Mary Harris (Dhavernas), a single mother and emergency doctor by day, who also moonlights as an underground angel of death — helping terminally ill patients who want to die and slip away on their own terms. So far Mary has managed to stay under the radar; but business is booming, and her double life is getting complicated.  When her world starts to unravel, Mary realizes she’s going to have to fight dirty if she’s going to stay in the killing game.

Also announced today are additional cast members joining Dhavernas in the series. Jay Ryan (Top of the Lake, Beauty and the Beast) has been cast as Joel, one of Mary’s terminally ill clients, but a mutual attraction blurs the lines of their doctor-patient relationship, while Richard Short (Vinyl, 666 Park Avenue) has joined as Des, Mary’s trusted partner in crime. Rounding out the cast is Lyriq Bent (Book of Negroes, Rookie Blue) as Frank, Joel’s friend who worries he’s getting in too deep with Dr. Death, Greg Bryk (Bitten, A History of Violence) as Grady, Mary’s drug supplier, Abigail Winters (Between, Saving Hope, Rookie Blue) as Mary’s teen daughter who learns that the people closest to her are not what they seem and Charlotte Sullivan (Rookie Blue) as Nicole, Mary’s concerned sister.

“With Tara’s dynamic and thought-provoking pilot script, Tassie’s stewardship, Holly on board, and an unbeatable cast now set, Mary Kills People has all the markings of a game-changing television event,” said Jocelyn Hamilton, President, Canada, eOne Television. “We are grateful to our long-time partners at Global for passionately embracing the project and can’t wait for viewers to embrace it with the same enthusiasm.”
