Quick Summary

The Parliamentary Budget Office reports that the Alto high-speed rail project between Toronto and Quebec City could cost between $75 billion and $113 billion, surpassing initial estimates of $60 to $90 billion. The higher costs are attributed mainly to tunneling and elevated structures, with each additional kilometer adding significant expenses. The report also notes that including a potential stop in Kingston adds uncertainty due to mixed construction challenges and environmental factors.

Story summary

The Parliamentary Budget Office (PBO) released a report on Thursday indicating that the cost of building a high-speed rail line between Toronto and Quebec City, known as the Alto project, could range from $75 billion to $113 billion. This estimate exceeds the federal government's previous projection of up to $90 billion. The PBO noted that adding a stop in Kingston, Ont. would increase uncertainty due to easier construction but higher population density and ecological sensitivity. The project aims to connect Toronto and Montreal within approximately three hours, aiming to revitalize transportation infrastructure but raising concerns about the growing national debt under Prime Minister Mark Carney's administration.
