An international search for a new CEO of Canadian National is underway following the news that Luc Jobin (left) is leaving the railroad effective immediately. In the interim Jean-Jacques Ruest (right) has been appointed by the board to serve as interim president and CEO. Ruest has been with the company for 22 years, the past eight as executive vice-president and chief marketing officer. Since Jobin's departure, CN has apologized for failing to keep grain shipments moving reliably by rail, and says it’s taking immediate steps to clear the backlog—including mobilizing more train cars and workers. The Chamber of Shipping has issued a statement on the backlog of all shipments and the need for improved fluidity and reliablity.
