High Liner Foods is buying back shares held by Nova Scotia Business Inc. for 4-million-dollars. The Lunenburg based seafood giant gave notice to shareholders earlier this month that it would buy back non-voting common shares. In 1984, the province invested 5-million-dollars in High Liner Foods, now the country's largest value-added seafood company. The shares have earned the province 5-point-3-million-dollars in dividends. High Liner employs 325 people in Nova Scotia.
