She's kept it quiet for two months but on Tuesday Linda Jeffrey stood in front of the lights and cameras to say she's done with Queen's Park.
Next to her husband, Jeffrey announced she has tossed away her post as Municipal Affairs Minister officially launching a bid for another political office - Mayor of Brampton.
Jeffrey claims she made the decision to clean up city hall, pointing to spending scandals and lawsuits.
She says she made up her mind in January and underlines Kathleen Wynne has been supportive, calling it a privilege to serve under the province's first woman premier.
Jeffrey brushed aside criticism she was launching a campaign inside Queen's Park, something other candidates are unable to do.
In a statement, Wynne called Jeffrey "a woman of integrity and honesty and I wish her all the very best in her next endeavours."
