Canada's main stock index rose Tuesday as energy and gold mining shares gained ground after falling in morning trading amid heightened tensions between Democratic People's Republic of Korea and the United States.

Six of the index's 10 main groups ended higher.

The Toronto Stock Exchange's benchmark Standard & Poor's/TSX Composite edged up 30.67 points, or 0.2 per cent, to close the day at 15,082.70.

Canada's top banks declined, with Bank of Montreal down two percent to 90.56 Canadian dollars, and Bank of Nova Scotia declining 0.6 percent to 76.73 Canadian dollars.

The Canadian dollar was trading at an average price of 79.90 U.S. cents, down 0.22 U.S. cent, while oil prices backtracked 60 cents to 45.97 U.S. dollars a barrel and gold prices jumped 6.90 to 1,322.20 U.S. dollars an ounce.

On the economic schedule, Statistics Canada reported that its industrial product price index fell 1.5 percent in July, mainly due to lower prices for motorized and recreational vehicles, while its raw materials price was down 0.6 percent in the same month, mostly attributable to lower prices for metal ores, concentrates and scrap.
