TORONTO: Canada's main stock index was little changed on Thursday, a day after the US Federal Reserve surprised markets by leaving its stimulative bond-buying program in place as declines in resource shares offset strength in high-yielding sectors like utilities and telecoms.

The Toronto Stock Exchange's S&P/TSX composite index unofficially closed down 4.62 points, or 0.04 percent, at 12,926.78. Six of the 10 main sectors on the index were higher.
