Trudeau built a pipeline to the West Coast. Now that Canada can sell oil to Asia, will Canadians benefit from owning it?

The federal government bought the Trans Mountain project, finished building it, and now owns the pipeline.

The case was that access to tidewater would reduce U.S. pricing power and open global markets like Asia. Now that the pipeline exists and Canada owns it, the question is simple.

Does public ownership mean Canadians benefit through toll revenue, better pricing leverage, and higher tax income? Or does it mainly mean the public took the risk while most of the upside still flows elsewhere?
