Popular Ottawa Liberal MP David McGuinty hinted he may run for the party's leadership next year.

While he didn't exactly say yes, he certainly didn't say no when prodded by CTV News Channel's Mercedes Stephenson at the party's biennial convention on Saturday.

McGuinty, brother of Ontario Premier Dalton McGuinty, said he owes it to himself, his family, constituents and the party to explore his options.

"I have to give it some consideration," he told Stephenson. "There's a lot at stake. I've got to find the best way to serve right now.

"It's a great privilege to serve in public life. It can be a tough life, a demanding life ... so I'm considering every option," he said.

McGuinty is no stranger to federal politics.

He's been elected four times in his Ottawa South riding and served at the forefront of the Liberal caucus as Opposition House leader, charged with facing off against Conservative pit bull John Baird.

McGuinty is well known for his heckling skills in the House and serves as energy and natural resources critic.

Interim leader Bob Rae, in an interview on CTV's Canada AM Friday, also didn't rule a run for the party's helm.
