Quotron Target of Suits: Two Canadian stock exchanges filed lawsuits accusing Quotron Systems Inc., a major distributor of financial information, of misusing data provided by the exchanges. The Toronto Stock Exchange and Montreal Stock Exchange sought a total of $53 million in damages and restitution for alleged breach of contract and fraud in use of market data from 1985 to 1989. The lawsuits said Quotron broke an agreement to cut off subscribers’ computer links to Canadian market data if they did not pay a fee for the information. Quotron spokeswoman Roxanne Taylor said the lawsuits were “without merit.”
