OTTAWA, Aug 24 (Reuters) - The Bank of Canada is asking Canadians for the first time to provide feedback on the inflation targeting framework it uses to set monetary policy, the central bank said on Monday. The bank has tried to keep the annual inflation rate at 2% since 1991, a goal that is reviewed jointly by the central bank and the federal government every five years. As part of its review, the bank says it plans to compare different monetary policy frameworks.
