Sept 4 (Reuters) - Canada's main stock index opened

subdued on Thursday after a softer-than-expected U.S. private

payrolls report, while investors awaited domestic employment

data that could influence the Bank of Canada's September

interest-rate decision.

At 9:31 a.m. ET (1331 GMT), the Toronto Stock Exchange's

S&P/TSX composite index was down 0.03% at 28,743.51

points.
