Em Siobhan McCourt is an award-winning genderfluid actor, director, producer, and stage-combatant whose creative mandate is to bring marginalized peoples to screens around the world. Originally hailing from Edmonton, Alberta, Em graduated theatre school in Alberta with distinction, performing as both an accomplished theatre actor and fiddle player across Canada. He moved to Toronto, Ontario to dive into film in 2015, and now moves between Canada and Ireland for work.

Em's debut film performance was a role in Matt Shakman's Cut Bank, which was the first film role he ever auditioned for, and the experience he has credited with igniting his passion for screen acting. Em pursued her career as an actor beginning in her late teens, and began following the drive to create when he moved to Toronto. Training primarily with Armstrong Acting Studios, Em developed a well-honed talent for honesty and grudging vulnerability that spans comedy (Kim's Convenience (2016)), historical (Murdoch Mysteries (2008)), drama (Jupiter's Legacy (2021)) and much in between.

Born in rural Alberta, Em and his family moved frequently during his childhood, living in Edmonton and Calgary, and even spending a year living in Ireland so that Em and her siblings could get to know their Irish extended-family. For years after, their friends all claimed Em and their siblings had developed deeper Irish accents.

He has created with Ariadne Deibert for their joint Youtube channel 5 Minutes You'll Never Get Back, and works to promote gender diversity with her production company Vicarious Playground Productions.

Em has dual citizenship with their homeland, Ireland.
