June 7 (Reuters) - Canadian National Railway Co CNR.TO
CNI.N said Chief Executive Claude Mongeau, who returned to
work in January after a six-month sick leave, will step down at
the end of this month.
Canada's biggest railway on Tuesday named Luc Jobin as its
new president and CEO, effective July 1.
"I was filled with joy returning at the helm earlier this
year, but I gradually came to realize that it is difficult to
fulfill such a demanding role given my new condition as a
laryngectomee," Mongeau said in a statement.
Mongeau took a break from the job in August 2015 after the
discovery of a rare type of tumor in his throat.
