Canada's main stock index was muted on Tuesday, as dismal earnings from Teck Resources Ltd and Restaurant Brands International Inc offset strength in energy stocks.

At 9:41 a.m. ET (13:41 GMT), the Toronto Stock Exchange's S&P/TSX composite index was down 7.43 points, or 0.05%, at 16,072.12.

The materials sector, which includes precious and base metals miners and fertilizer companies, recouped early losses and added 0.1% as gold futures rose 0.1% to $1,904.6 an ounce.

Teck Resources shed 5.6%, the most on the TSX, after the company missed analysts' estimates for quarterly profit, hurt by a steep drop in the prices of steelmaking coal.

The second-biggest decliner was Restaurant Brands International, down 2.9% after the restaurant chain posted third-quarter profit below analysts' estimates.

On the TSX, 141 issues were higher, while 74 issues declined for a 1.91-to-1 ratio favouring gainers, with 15.65 million shares traded.

The largest percentage gainer on the TSX were Colliers International Group Inc, which jumped 10.5% after the real estate service provider reported upbeat quarterly results.

Cenovus Energy Inc rose 5.2%, marking its second session in black, two days after the oil producer said it would buy rival Husky Energy Inc.

The most heavily-traded shares by volume were Nevada Copper Corp, Bank of Montreal, and Royal Bank of Canada.

The TSX posted no new 52-week highs and no new lows.

Across all Canadian issues there were one new 52-week highs and two new lows, with a total volume of 27.25 million shares.
