AB:The boom and bust cycles Alberta has experienced since the 1970s were mirrored in the career of Peter Pocklington who owned the Edmonton Oilers hockey team. He bounced from success to failure – first building a business empire which included an auto dealership; real estate; food processing, oil and financial trust companies. The Oilers, led by Wayne Gretzky and then Mark Messier, won 5 Stanley Cups between 1984 and 1990. But the sale of "The Great One", labour troubles, and the collapse of his companies led to financial problems off the ice and a losing hockey team on the ice. He was forced to sell the franchise in 1997.
