TORONTO, Aug 3 (Reuters) - Toronto's main stock index retreated from a six-week peak but still ended higher on Tuesday as a weak U.S. dollar helped boost energy issues and investors played catch-up with prices on other stock markets after a holiday Monday in Canada.
The index's hefty energy sector, up 1.3 percent, led the charge with Suncor Energy Inc (SU.TO) up 2.4 percent at C$34.71, and Canadian Natural Resources (CNQ.TO) rallying 2.3 percent to C$36.21. The price of oil pierced a three-month high above $82 a barrel. [O/R]
The index's materials group rose 0.9 percent as gold prices climbed, boosting such names as Barrick Gold (ABX.TO), up 0.5 percent at C$42.46, and First Quantum Minerals (FM.TO), up 4.6 percent at C$67.37.
The TSX was closed on Monday, missing out as stock prices rose in the United States and elsewhere.
"The main reason why we're doing so well really is because we're playing catch-up to what transpired in not just the States but world markets over the (Canadian) holiday," said Levente Mady, market strategist at Union Securities in Vancouver.
U.S. stocks closed at their highest level in 10 weeks on Monday, while global markets surged, in part as European bank earnings boosted optimism. Analysts also said the TSX's rise on Tuesday reflected lingering optimism about Monday's U.S. data, which showed manufacturing growth in July was better than many analysts had expected.

On Tuesday, the Toronto Stock Exchange's S&P/TSX composite index .GSPTSE finished the session up 69.17 points, or 0.59 percent, at 11,782.60, with eight of its 10 main sectors higher. Earlier, the index touched a six-week high of 11,872.89.

Separately, there were reports the BlackBerry maker RIMM.O may be considering concessions to India and Kuwait after their governments voiced concerns that the BlackBerry could be a security threat. [ID:nLDE6720WQ] For more related stories, please see: [ID:nN02151382]
RIM shares were the top net loser on the market, and closed 4 percent lower at C$56.77.
Gold miner Kinross Gold Corp (K.TO), down 6.4 percent at C$15.79, was the most heavily traded stock on the TSX. Kinross said it will buy the 91 percent of Red Back Mining Inc RBI.TO that it does not already own for around $7 billion to create one of the world's largest gold miners.
Red Back Mining shares, the second most heavily traded stock on the market, rallied 5.5 percent to C$27.45. [ID:nN02108994]
Gold miners generally supported the TSX's move higher as investors speculated about the potential of other mergers and acquisitions, said Gareth Watson, Canadian Equity Advisor, Portfolio Advisory Group, ScotiaMcLeod.
"Gold stocks are potentially reacting to that proposed merger between Kinross and Red Back. Whenever you see that type of M&A activity, that sometimes sparks speculation about who else may be on the M&A block next," Watson said.
The blue chip S&P/TSX 60 index .TSE60 closed 3.50 points, or 0.51 percent, higher at 688.53.
