A source familiar with the plans told QP Briefing that the two leaders will be joined in Ottawa by their respective finance and industry ministers to unveil a support package designed to help businesses and workers navigate ongoing trade disruptions.

The proposed changes will be included in an upcoming package of legislation expected to be introduced during the fall session at Queen's Park.

Under the changes, the province will appoint the chairs of Durham, Halton, Muskoka, Peel, Waterloo and York regions, as well as the warden of Simcoe County. Niagara's regional chair is already appointed by the province.
