Dec 12 (Reuters) - Futures for Canada's benchmark stock index edged higher on Friday after the index notched a record closing high in the previous session, in a week filled with highly anticipated central bank meetings.

Canada's TSX index .GSPTSE ended the prior session at 31,660.73 points, boosted by metal prices and domestic data, while the S&P 500 and Dow also posted record closes.

Futures on the S&P/TSX Composite Index SXFcv1 were up 0.2% at 1857.80 points by 06:20 a.m with the TSX poised for a weekly gain. The index is up 28% for the year and has outperformed its Wall Street peers due to a stellar performance from its mining and materials shares.

Investor sentiment this week was buoyed by a widely anticipated 25 bps cut from the U.S. Federal Reserve, while the Bank of Canada kept rates on hold, pointing to a resilient economy.

On Thursday, Canada posted a monthly international trade surplus in September, reversing a trend of seven consecutive months of deficits.

Gold XAU= prices hit a seven-week high, helped by a soft dollar, while silver XAG= extended its run at record prices. Copper was also trading near record peaks.

Oil LCOc1, CLc1 prices gained on concerns of supply over Venezuelan disruptions.

U.S-listed shares of Canadian cannabis companies Canopy Growth WEED.TO and Tilray Brands TLRY.TO rose premarket after a Washington Post report said U.S. President Donald Trump is expected to push the government to dramatically loosen federal restrictions on marijuana.
