Raised in Montreal, Caroline moved to New York in 1989 to study stand-up comedy at the New School of Social Research. She says her true training came from her first gigs at comedy club Catch A Rising Star. Performing around New York City, she quickly gained a reputation, and a name in the city's competitive comedy scene. These performances were augmented with appearances on MTV's Half-Hour Comedy Hour, Comic Strip Live and Caroline's Comedy Hour.
She then decided to move on to Los Angeles for a career in Hollywood, debuting in NBC television series Pride and Joy, with Jeremy Piven. She likely gained most fame for her role as Aunt Hilda on The WB's Sabrina, The Teenage Witch, and being a regular on Hollywood Squares.
