Katia was born in Beirut, Lebanon and grew up in Saudi Arabia until the age of five. Of Armenian descent, the whole family moved to Montreal, Canada in 1985. As a child, Katia was always imitating characters and learned the art of performing at a young age. Her mother and aunt taught her piano and she continued her music entering a specialized music school. She performed recitals and concerts until the age of 20. She never gave acting a thought seeing as she came from a conservative family and their hopes of her entering engineering. She was soon bitten by the acting bug, and entered John Abbott College, in the Professional Theatre Department. Upon graduation, she moved out West to Vancouver and studied Acting for Film. Soon after school, she got an agent and on her first ever audition landed the supporting role in "Traffic" (2004).
