TORONTO (Reuters) - The Toronto Stock Exchange's main index ended sharply higher, boosted by resource issues, as healthy US economic data put investors in a buying mood after a week of volatility.The S&P/TSX composite index finished up 135.19 points, or one percent, at 13,859.52, making up for its 108.49 point loss in the previous session.

North American stock markets got a mid-afternoon boost after the US Federal Reserve's Beige Book said US economic activity expanded from mid-April through May and that overall wage pressures had not risen.

Strong US retail sales, consumer spending data and lower bond yields also helped prod investors.

The markets have been sensitive to rate-hike worries, as well as volatility in Chinese stocks.

"They're temporary things," said John Kinsey, portfolio manager at Caldwell Securities.

"They're not long-lasting and then the bulls take over again and that's what's happened today. It's the usual suspects: the oils, materials and the financials."

All of the index's 10 main sectors were higher, led by a 1.6 percent rise in the resource-laden materials group and a 0.9 percent jump in energy shares. Combined, the sectors make up more than 40 percent of the index's weight.

The heavyweight financials group, which comprises about 30 percent of the market, rose 1.1 percent.

Shares of aluminium producer Alcan rose 74 Canadian cents, or less than 1 percent, to C$88.47, while zinc miner Teck Cominco surged C$1.86, or four percent, to C$47.85.

Earlier Wednesday, Alcan said it was considering its alternatives to a US$28.4 billion hostile take-over offer from US-based Alcoa.

It also said it signed a long-term deal to supply Airbus with a variety of high-performance products for its aircraft.

Energy shares got a boost from higher crude prices after US inventory data showed gasoline stockpiles below normal at the start of the summer driving season.

Canadian Natural Resources rose C$1.20 to C$70.68, and EnCana climbed 82 Canadian cents to C$67.06.

In financials, Bank of Nova Scotia climbed C$1.07 to C$52.99, while Royal Bank of Canada rose 71 Canadian cents to C$57.06.
