TORONTO -- Ontario's premier says the revised Trans-Pacific Partnership must not come at the expense of key Ontario sectors, including the auto industry.

Kathleen Wynne says while freer trade and diversification is a good thing, she has heard concerns from many in the automotive sector over the course of TPP negotiations.

Wynne says she will continue to stand up for those Ontario jobs and for all of the province's workers and businesses.

Canada and the remaining members of the old Trans-Pacific Partnership said Tuesday they will forge ahead with the trade deal without the United States.

The fresh commitment leaves Japan as the largest player in a new 11-nation pact that spans two hemispheres and includes Canada and Mexico.

But with only a few publicly available details following the announcement, many questions remain unanswered.

"We will have more to say on Canada's decision to sign the Comprehensive and Progressive Agreement for Trans-Pacific Partnership once we learn all the details of this new trade agreement," Wynne said in a statement.

Wynne said she will work "to make sure we are achieving the best possible deal for Ontario."
