Moraille will make her candidacy official during a news conference set for Tuesday morning in Montreal North.
A byelection is expected to be called in the coming weeks in the riding to replace Liberal MP Denis Coderre, who is a candidate for mayor of Montreal.
Moraille, a native of Haiti, is a lawyer in arts and communications and has been with the law firm of Lussier & Khouzan since 2006.
With Bran Van 3000, Moraille sang lead on the band’s biggest hit, "Drinking in LA" and won several awards, including a Juno for "Glee" in 1998.
Another high-profile candidate will run in a byelection in the Bourassa riding — former NHL enforcer George Laraque for the Green party.
Bourassa — a diverse north-end riding with various ethnic groups and home to a large Haitian population — has been held by Coderre for the past 16 years.
Note to readers: This is a corrected story. An earlier version carried an incorrect spelling for Stephane Moraille's first name.
