As Dwight Duncan officially announces he won't be going after the Ontario Liberal leadership or seeking re-election as MPP, the provincial finance minister says he's not ruling out politics all together.

Duncan says he always thought about serving an MP one day. Duncan's provincial riding of Windsor-Tecumseh is held federally by NDP MP Joe Comartin.

Until then, he says he will do whatever he can to help the Ontario Liberals get re-elected. He says while he will support long-time friend and former Liberal Minister Sandra Pupatello if she decides to thrown her hat into the ring, Duncan underlined he will not take an active role in the leadership race.

At the federal level, Duncan says he likes the prospect of Justin Trudeau and Marc Garneau taking over the top job.

Duncan says he doesn't have a job lined up yet, as he waits for an election to be triggered in Ontario.

With both the Premier and long-time MPP Greg Sorbara resigning recently, he says he doesn't think people are jumping ship, pointing to what he calls "talented back rows" in MPPs like Teresa Perruza.

Duncan says he always believed governments have a life-span of eight years, and that's when people are compelled to move on. Dalton McGuinty has been in power since 2003.
