May 31 (Reuters) - Canada's main stock index opened

higher on Friday, as bets of a June rate cut by the Bank of

Canada rose after the domestic economy missed first-quarter

growth forecast, while the much-awaited U.S. inflation data came

in line with estimates, lifting broader sentiment.

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

S&P/TSX composite index was up 42.91 points, or 0.19%,

at 22,114.62.
