Canadian National Railway Claude Mongeau was president and CEO of Canadian National Railway from 2010 to 2016, previously serving as CFO for almost a decade.

Mongeau's promotion to CEO resulted in the resignation of several senior executives. Four years into his tenure, the company experienced a 73% increase in mainline derailments, which The Globe and Mail described as a "deterioration" of its safety record. As a result, Mongeau's bonus was reduced.

During his overall tenure, operating ratio declined from 63.6% to 55.9%.

Norfolk Southern Railway Mongeau, who has served as an independent director on the Norfolk Southern board of directors since 2019, was appointed as the chairman of the board in 2024. Mongeau's new role as chairman of the board also includes chairing the executive committee, reflecting his time in the railway industry. His appointment comes during a critical time for Norfolk Southern in managing the aftermath of the 2023 East Palestine, Ohio, derailment.

SNC-Lavalin Mongeau was a member of the board and audit committee of SNC-Lavalin while he was working full-time as the CEO of Canadian National. While he was on the board at SNC-Lavlin, the company was caught paying bribes to government officials in Libya, amounting to $48 million over a decade.

While on the audit committee, Mongeau helped oversee an investigation into the scandal, leading to the resignation of the CEO and the company being charged with fraud and corruption. During the audit committee investigation, the Financial Post wrote a story critical of full-time CEOs serving on the boards of directors of other companies, calling out Mongeau by name.
