During the period that John Crow was Governor of the Bank of Canada—1987 to 1994— there was a worldwide recession and the bank rate rose to around 14% and unemployment topped 11%. Although since that time inflation-targeting has been adopted by "most advanced-world central banks", in 1991 it was innovative and Canada was an early adopter when the then-Finance Minister Michael Wilson approved the Bank of Canada's first inflation-targeting in the 1991 federal budget. The inflation target was set at 2 per cent. Inflation is measured by the total consumer price index (CPI). In 2011 the Government of Canada and the Bank of Canada extended Canada's inflation-control target to December 31, 2016. The Bank of Canada uses three unconventional instruments to achieve the inflation target: "a conditional statement on the future path of the policy rate", quantitative easing, and credit easing.
