By John Tilak TORONTO (Reuters) - Canada's main stock index rose on Thursday as shares of energy and gold producers jumped with commodity prices, offsetting a decline in BlackBerry Ltd. A Reuters report, citing a person familiar with the matter and documents, said on Wednesday that Samsung recently talked to BlackBerry about buying the smartphone maker for as much as $7.5 billion. BlackBerry shares, which shot up nearly 30 percent in the previous session, were down 16.4 percent at C$12.55. “Gold made a dramatic move today, breaking out of the resistance levels and the stocks are reacting on the positive,” said John Ing, president of Maison Placements Canada. The Toronto Stock Exchange's S&P/TSX composite index was up 62.01 points, or 0.44 percent, at 14,146.44.
