(Reuters) – Futures tracking Canada’s main stock index edged up on Wednesday, mirroring their Wall Street peers, ahead of the U.S. Federal Reserve’s monetary policy decision later in the day.

December futures on the S&P/TSX index were up 0.2% at 5:42 a.m. ET (1042 GMT).

Cananda’s main share index touched a four-week low on Tuesday, hurt by lower oil prices and political unrest in Canada.
