Luc Jobin, the ceo of Canadian railway operator CN Rail, has stepped down with immediate effect.
Jean-Jacques Ruest has been appointed as interim president and ceo until a permanent replacement is in place.
CN said that in an increasingly competitive market, the company must act with speed and innovation to retain its leadership position. The company also highlighted the immediate operational and customer service challenges it has been facing since autumn 2017 - a result of high demand and insufficient network resiliency, coupled with severe winter weather conditions.
"The board believes the company needs a leader who will energise the team, realise CN's corporate vision and take the company forward with the speed and determination CN is known for," said board chairman Robert Pace.
An international search for a new ceo is now under way.
