Ontario Premier Doug Ford says Mississauga Mayor Bonnie Crombie should quit her day job if she decides to run for the Liberal party leadership.
Crombie recently said she's exploring a leadership bid for the provincial Liberals, who captured just eight seats in last year's election.
She has said she'll continue on as mayor while she mulls a leadership bid.
Ford, whose Progressive Conservatives were re-elected with a majority, says it would be a ``slap in the face'' to Mississauga residents for Crombie to remain mayor while running for Liberal leader.
A deadline of Sept. 5 has been set for candidates to register to run for Liberal leader. Contestants must pay an entry fee of $100,000 and a refundable $25,000 deposit.
Party members will cast their votes by ranked ballot on Nov. 25 and Nov. 26 and the Liberals will announce their new leader on Dec. 2.
