Premier McGuinty's decision to step down as liberal leader is a surprise to Thunder Bay MPP Bill Mauro who says McGuinty has been good to the north. Mauro says we have made great strides in this part of the province, and it couldn't have happened without McGuinty. Mauro says he respects McGuinty's decision and says he personally thanked the premier for the support he has shown to him and his riding of Thunder Bay-Atikokan
