Sylvie Moreau was born in Montreal. Both of her parents were teachers and they had 5 children. Her siblings all went into the acting business as well. Sylvie married François Papineau (born 1966, Laval), who is also an actor. The couple met while they co-starred in Célestine.
If Sylvie Moreau became one of the mass audiences favourites because of her regular presence on television (Catherine, Dans une galaxie près de chez-vous), she’s also thrived on stage (notably in Les voisins — Compagnie Jean Duceppe, L’odyssée — CNA and TNM, Un fil à la patte — Théâtre du Rideau Vert and CNA, La salle des loisirs — Théâtre d’Aujourd’hui, and all the Momentum productions) and on the big screen: Familia (L. Archambault), Les aimants (Y. Pelletier), Camping sauvage (A. Ducharme), Dans une galaxie près de chez vous (C. Desrosiers), Les immortels (P. Thinnel), Le manuscrit érotique (J.P. Lefebvre) and La bouteille (A. Desrochers).
Moreau won a Genie Award in January 2000 for Best Performance by an actress in a leading role for her work in Post Mortem, in which she co-starred with Gabriel Arcand. She also won a Gémeaux award for her work in the series, Catherine, which she wrote as well as starred as the title character. A graduate of the Université du Québec à Montréal, she took extensive courses as a mime at the École de mime corporel de Montréal.
