Jan 4 (Reuters) - Canada's main stock index opened subdued on Thursday as data hinting at resilience in the U.S. labor market dampened investor optimism around early rate cuts, while strength in the energy sector cushioned against losses.

At 9:30 a.m. ET (1430 GMT), the Toronto Stock Exchange's S&P/TSX composite index was down 1.7 points, or 0.01%, at 20,816.88.
