CANADA STOCKS-TSX higher shortly after open; Shopify falls sharply

TORONTO, Oct 31 (Reuters) - Canada's main stock index rose on Tuesday as financial stocks kept the index in positive territory despite a hefty decline in Shopify Inc shares and weaker resource stocks.

The Toronto Stock Exchange's S&P/TSX composite index was up 13.09 points, or 0.08 percent, at 16,015.87 shortly after the open.

Six of the index's 10 key sectors rose, but information technology fell 0.9 percent on Shopify, which was down 7.8 percent. (Reporting by Solarina Ho; Editing by Chizu Nomiyama)
