Well, I guess it's (finally) official. From CTV:
Justin Trudeau has confirmed to CTV News that he will take on the Bloc Québécois in the next federal election when he runs for the Liberals in the Montreal-area riding of Papineau.
Trudeau was originally expected to run in the Montreal-area Outremont riding, recently vacated by Jean Lapierre, a former Liberal cabinet minister.
Instead, he will seek nomination in the tougher Papineau seat, currently held by Bloc MP Vivian Barbot.
"I don't want to be handed anything, I don't need to be handed anything, I'm more than capable of bringing the fight and it will be a chance for me to demonstrate my own political abilities," said Trudeau.
