Justin Trudeau makes the leap into federal politics in Papineau. Now held by the Bloc (by less than a thousand votes in the last election), Papineau is Pierre Pettigrew's old riding. It's also the smallest geographically and one of the poorest.

(Perhaps confusingly, Quebec also has an electoral district called Papineau, which lies north of the Ottawa river between Argenteuil and Gatineau ridings.)
