The Montreal Exchange said it namedBruno Riverin, president of Quebec's Caisse centrale
Desjardins, as its new president and chief executive officer.
    Riverin replaces former exchange president Andre Saumier,
who resigned in January to set up a brokerage firm.
    Riverin's appointment is effective March 26, the exchange,
Canada's second largest, said.
    The Caisse central is the main investment arm of Quebec's
huge credit union movement.
