TSX opens higher on healthcare, materials support

Canada's main stock index opened slightly up on Tuesday, supported by a rise in material and healthcare stocks, while investors assessed stronger-than-expected producer prices data from the U.S. that dampened hopes of interest rate cuts this year.

At 9:31 a.m. ET (13:31 GMT), the Toronto Stock Exchange's S&P/TSX composite index TSX was up 30.97 points, or 0.14%, at 22,290.14.
