Skeena-Bulkley Valley NDP MP Nathan Cullen's new job is to keep new Finance Minister Joe Oliver in check.
A shadow cabinet shuffle Thursday moved Cullen from the House Leader of the Official Opposition to the party's finance critic.
"I'm honoured and incredibly excited to take on this new assignment," Cullen said in a news release. "We've seen the Conservative government take a Bay Street perspective on managing Canada's economy for too long, giving reckless tax cuts to industries that don't need them, and leaving Canadian families to pick up the slack."
Cullen replaces Toronto MP Peggy Nash in the high-profile finance critic role.
Prime Minister Stephen Harper named Oliver the finance minister Wednesday, a day after Jim Flaherty resigned from cabinet.
