TORONTO, Sept 1 (Reuters) - Canada’s main stock index moved slightly higher on Thursday as gold miners bucked bullion’s fall after an August sell-off and investors cheered the expansion of Tim Hortons into Britain.

The coffee and doughnut chain’s owner Restaurant Brands International Inc was among the most influential movers on the index, up 2.2 percent to C$63.73.

Gold miners also gained, even as the price of gold fell, after having lost significant ground over the course of August, with Barrick Gold adding 2.5 percent to C$22.84.

At 10:14 a.m. EDT (1414 GMT), the Toronto Stock Exchange’s S&P/TSX composite index was up 51.04 points, or 0.35 percent, to 14,648.99.
