Dhavernas was born in Montreal, Quebec, the daughter of the Québécois actors Sébastien Dhavernas and Michèle Deslauriers. Her first name is pronounced like "Carolyn" because of her French-Canadian heritage. Her last name is roughly pronounced "Daverna" for the English-speaking audience but originally pronounced "Davernaus" (aus like house). Her sister Gabrielle Dhavernas is also an actress and specialises in dubbing. The voice timbre of both actresses is very similar, so similar that Gabrielle can dub the voice of Caroline. She learned English at a very young age, as her parents sent her to an English-speaking elementary school.
