The Globe and Mail reports in its Friday edition that a report from Parliamentary Budget Officer Annette Ryan estimates that building a dedicated high-speed rail line between Toronto and Quebec City could cost between $75-billion and $113-billion. The Globe's Bill Curry writes that the PBO's range exceeds the $60-billion to $90-billion estimate from Alto, the Crown corporation overseeing the project. Alto has said its range is a preliminary estimate that will be refined and updated next year. The PBO report released Thursday is based on a review of international examples of the per-kilometre cost of building high-speed rail. Both the PBO's figures and Alto's estimates only include the cost of building the new line. The PBO report does not estimate the project's operational costs, saying ridership revenue coverage will be addressed in a future report. An internal document from 2023 shows operating and maintaining the line is estimated to cost between $62.6-billion and $67-billion over 40 years. That is in addition to the cost of construction. When construction and operational costs are combined with rolling stock purchases, the internal report said the total price tag over 40 years would be around $150-billion.
