TORONTO - Premier Dalton McGuinty is insisting his deputy premier isn't going anywhere and says he won't shuffle his cabinet despite George Smitherman's musings about running for mayor of Toronto.

McGuinty says Smitherman is working “as hard as ever” to implement the Green Energy Act, a key piece of legislation aimed and creating thousands of jobs in the province.

After months of denying he is eyeing the mayor's job, Smitherman gave a strong signal three weeks ago that he's considering making a bid.

His comments led to talk of a cabinet shuffle, with Attorney General Chris Bentley rumoured to possibly be poised to take over as minister of energy and infrastructure.

NDP Leader Andrea Horwath says it's time for Smitherman to declare his intentions to avoid further distractions.

Smitherman has left the door open for a possible run since his initial comments and promised to decide by January.
