BRAMPTON, Ont. - Ontario Premier Dalton McGuinty is dismissing reports he may be considering a run for the federal Liberal leadership.

Several high-profile federal Liberals attended McGuinty's speech to the Economic Club of Canada on Tuesday, prompting renewed speculation he may run for federal party leader.

McGuinty has always rejected notions of running federally in the past, and today said he has not changed his mind.

He joked with reporters that he "wants to remain married."

McGuinty is in his third term as premier of Ontario, but was elected with only a minority government last month after two previous majorities.

He welcomed interim federal Liberal Leader Bob Rae at his speech Wednesday, a rare public mention from McGuinty of Ontario's former NDP premier.
