text: In 1998, the production company now known as Motion International asked Vanasse to co-host a Québec-based children's science show, Les Débrouillards. Producer Lorraine Richard and director Léa Pool spotted her there, and offered Vanasse her first big break in the role of Hanna in Set Me Free (Emporte-moi) (1999), a story of a teenager trying to find her identity in a tormented family environment. The film was presented at forty festivals, and shown in twenty countries. Her performance was highly acclaimed both nationally and internationally and earned her the 2000 Best Actress Jutra Award.
  Vanasse then played Lucie (the teenage love interest of Benoit Langlais's main character, Zac) in the controversial Québec TV series Deux frères (fr) (1999). Her character became very prominent in 2000–2001, and the debate stirred by the violent realism led her to become, together with Langlais, a spokesperson for the government-funded TV program Parler, c'est grandir, a broadcast aimed at youngsters from unstable backgrounds. In 2001, she applied for the ITHAKA program and took a six-month break in Greece to devote herself to travel and academics, after which she played Donalda in Charles Binamé's epic, Séraphin: Heart of Stone (Séraphin: un homme et son péché) (2002). She was cast as an FLQ terrorist in the 2006 miniseries October 1970 on CBC's English network. Vanasse appeared in such Canadian productions as Sans Elle, Ma fille, mon ange, and the Canadian/American/British mini-series Killer Wave.
