Aug 29 (Reuters) - Canada's main stock index opened

subdued on Friday, weighed down by technology shares, but the

decline was limited by weaker-than-expected domestic GDP data,

which signaled potential interest rate cuts by the central bank.

At 9:30 a.m. ET (1330 GMT), the Toronto Stock Exchange's

S&P/TSX composite index was down 0.04% at 28,423.09

points.
