June 3 (Reuters) - Futures for Canada's main stock index

slipped on Monday as investors turned cautious ahead of the Bank

of Canada's interest rate decision and more economic data later

this week.

June futures on the S&P/TSX index were down 0.2% at

6:45 a.m. ET (10:45 GMT).

The main event for the week would be the BoC's rate decision

on Wednesday. The central bank is expected to trim interest

rates to 4.75%, according to three-quarters of economists in a

Reuters poll that showed three further cuts this year, with the

last one hanging on a knife's edge.

The loonie was marginally higher against the U.S.

dollar at C$1.3654.

The expectations of a rate cut were boosted after the

Canadian economy expanded at a slower-than-expected pace in the

first quarter, data showed on Friday.

Investors will also closely monitor the domestic labor

market report, due end of the week, for the central bank's

future interest-rate path.

Meanwhile, S&P Global's manufacturing Purchasing Managers'

Index (PMI) for May is due at 0930 ET.

Among sectors, materials could be in focus after copper

prices rose as data from top consumer China showed stronger

factory activity and U.S. inflation data reinforced hopes of

interest rates cuts by the Federal Reserve this year.

The Toronto Stock Exchange's S&P/TSX composite index

ended higher on Friday, adding to its monthly gain, as

investors rotated to more defensive areas of the market.

Across the border, futures linked to S&P 500 and

Nasdaq Composite climbed as U.S. Treasury yields fell

after Friday's inflation data raised hopes of interest rate cuts

in 2024.

In individual stocks, brokerage RBC cut the rating of Canada

Western Bank to 'sector perform' from 'outperform',

while National Bank of Canada made a similar rating change on
