Ontario is on board with the Supreme Court of Canada's ruling requiring consent from all provinces before any changes are made to the senate.
The premier says Ontario needs to be a part of any decision about changing "the character of the Senate."
In a written statement, Kathleen Wynne says she believes the Senate plays a "valuable role as a chamber of sober second thought,"and any changes must be consistent with that function.
Wynne underlines she's pleased that the Supreme Court has upheld the Ontario government's view that Ottawa must work with provinces.
She says if the federal government plans to lead a national senate reform discussion, Ontario will be happy to participate.
