New Municipal Affairs Minister

Premier Dalton McGuinty has named Environment Minister John Gerretsen as Ontario's new interim minister of municipal affairs and housing.

This after former minister Jim Watson confirmed he's quitting cabinet and will resign as a member of the Ontario legislature shortly, to run for mayor of Ottawa.

McGuinty is expected to make a more permanent shuffle to his cabinet next week to replace former deputy premier George Smitherman who stepped down last week and Watson on a more permanent basis, but other significant changes are also expected.
