TORONTO, Nov 16 (Reuters) - Canada's main stock index broke a six-day losing streak on Thursday, helped by gains among its biggest banking stocks as bond yields rose, while continued weakness in oil prices weighed on its energy companies.
* The Toronto Stock Exchange's S&P/TSX composite index ended the session up 56.89 points, or 0.36 percent, at 15,935.37.
* It had fallen 1.6 percent prior to Thursday's session since closing at an all-time high of 16,131.79 on Nov. 7.
* The energy group retreated 0.7 percent, with Seven Generations Energy Ltd falling 9.2 percent to C$16.58 after announcing its capital investment plans for 2018. Suncor Energy Inc lost 0.8 percent to C$45.02 as oil prices extended their falls on worries about U.S. oversupply.
* The financials group, which accounts for more than a third of the index's weight, gained 0.7 percent as bond yields in both Canada and the United States moved higher. Bank of Nova Scotia rose 0.9 percent to C$83.99 and Canadian Imperial Bank of Commerce added 1.2 percent to C$114.18.
* Shares in Shopify Inc rose 6 percent to C$132.51 after the commerce software company said it had reached a deal with United Parcel Service Inc to provide its U.S. member merchants with discounted shipping rates.
* Among the most active Canadian stocks by volume were Aurora Cannabis Inc, down 13.2 percent to $5.40 and Canopy Growth Corp, down 6.5 percent to $17.26.
* Canopy Growth said late on Wednesday that it was investing in fellow marijuana producer TerrAscend Corp. Aurora said it had arranged a $100 million financing.
