TSX falls as earnings misses, oil price fall weigh

TORONTO (Reuters) - Canada's main stock index fell in morning trade on Wednesday as energy shares followed oil prices lower, a small financial technology company plunged after its earnings missed expectations, and the country's largest railway posted a fall in revenue. The energy group retreated 1.4 percent, with oil back below $50 a barrel as U.S. inventories rose and more doubts emerged about OPEC's ability to strike an effective deal to cut production next month.
