March 12 (Reuters) - Canada's resource-heavy main stock index looked set to open lower on Monday, hurt partly by a drop in commodity prices after weak trade data from China.
China's trade balance plunged $31.5 billion into the red in February as imports swamped exports to leave the largest deficit in at least a decade and fuel doubts about the extent to which frail foreign demand or seasonal distortion drove the drop.
