The federal budget watchdog has warned that the construction of a high-speed rail line between Toronto and Quebec City could exceed Ottawa's projected costs. The report, issued by the watchdog, highlights potential financial risks associated with the project. The estimated cost of the rail line was initially set at a specific figure, but the watchdog suggests that actual expenses may be significantly higher. This warning comes as the project moves forward with planning and initial construction phases. The report does not specify the exact amount of the projected cost, but it emphasizes the need for careful financial oversight. The federal government has not yet responded to the watchdog's findings. The rail project is part of broader infrastructure plans aimed at improving transportation across Canada. The warning underscores the challenges of large-scale infrastructure projects and the importance of accurate budgeting.
