This led to an invitation in 2001 from singer-songwriter Daniel Bélanger to join his band as a keyboardist and vocalist in support of his well-received album Rêver mieux.

In 2004, Moffatt met French rock musician Matthieu Chedid at Montreal's FrancoFolies music and performance festival.

She subsequently remixed Chedid's "La Bonne Étoile" (from his 2003 album Qui de nous deux) as a virtual duet.

Her version of the popular song received wide airplay in France and helped introduce her to French music fans.

[3] In 2010, Moffatt contributed twelve tracks (all covers of English-language songs) to the popular Radio-Canada medical show Trauma, which were subsequently released as a soundtrack album.

[9] In March 2019, she was one of 11 singers from Quebec, alongside Ginette Reno, Diane Dufresne, Celine Dion, Isabelle Boulay, Luce Dufault, Louise Forestier, Laurence Jalbert, Catherine Major, Marie Denise Pelletier and Marie-Élaine Thibert, who participated in a supergroup recording of Renée Claude's 1971 single "Tu trouveras la paix" after Claude's diagnosis with Alzheimer's disease was announced.

On 26 February 2012, Moffatt came out as lesbian in an interview with Guy Lepage on the popular Quebec talk show Tout le monde en parle.
