Ontario Transport Minister Prabmeet Sarkaria says the federal government conceded to “fringe groups” in rejecting a plan to allow jets to land at Toronto’s Billy Bishop Airport.

“If this is how they’re going to treat bigger projects, I don’t think you’ll get much built,” he said at a Tuesday news conference in St. Thomas, Ont., while promising to move ahead with the plan.

A source with knowledge of the discussions told CBC News that, in response, Ontario is now rethinking its support for the Alto high-speed rail project.

Several hours after that conversation, 11 MPPs from Ontario put out a statement questioning Alto.
