John Roth (businessman)

John Andrew Roth is a Canadian retired business executive. He was the chief executive officer and chairman of Nortel Networks between 1997 and 2001. While he was called "the most successful businessman in modern Canadian history" by Time magazine and named Canada's CEO of the Year by a Bay Street panel in the fall of 2000, by the ignominious end of his career it became clear that his mismanagement destroyed the company.
