Dec 11 (Reuters) - Futures tied to Canada's resources-heavy main stock index fell on Monday, tracking a decline in commodity prices, while investors await a raft of economic data and decisions from major central banks during the week. More inflation data out of the United States, including November consumer prices, would be on the watchlist ahead of the Fed's rate decision. Among individual stocks to look out for, TD Securities downgraded Orla Mining OLA.TO to "hold" from "buy".
