Claude Mongeau, chief executive officer of Canadian National Railway Co., is scheduled to have surgery on a "precancerous" tumour on his larynx, the company said on Wednesday.
Chief financial officer Luc Jobin will run the leadership team while Mr. Mongeau undergoes surgery in the coming weeks, followed by radiation therapy, the company said in a statement.
"This is a serious health setback for me personally, but one of CN's core strengths is that we have a very experienced and tightly knit senior team that knows how to lead our railway to success," Mr. Mongeau said in a letter addressed to the Montreal-based company's employees.
Mr. Mongeau, in his early 50s, said the tumour has not spread.
