She trained for 2 months with the Pointe-Claire Swim Club to
convincingly portray Marilyn Bell in Heart: The Marilyn Bell Story (2001), who was the first to cross 32-mile
Lake Ontario in 1954.
She's used to doing her own dubbing for the French versions of her TV shows.
Her sister Gabrielle Dhavernas is also an actress and specializes in dubbing. The voice timbre of both actresses is so similar that Gabrielle can dub the voice of Caroline.
Her first name is pronounced Caro"lean" because of her French-Canadian heritage.
She learned English at a very young age, as her parents sent her to an English-speaking elementary school called The Priory School.
