Weaker than expected first quarter growth out of the United States failed to damper the mood during Wednesday trading on the Canadian Markets. For the tale of the tape, the TSX Exchange rallied 0.73%, while the TSX Gold Index tacked on 0.4% and the TSX Venture Exchange, Canada’s largest junior exploration bourse, surged 2.10% with the advancers beating out the decliners by a 486 to 316 margin on good volumes of 205 million shares traded.
