To track how firms were affected by the appreciation of the Canadian dollar in 2003 and 2004 and the steps they took in response, the Bank included supplementary questions in the quarterly Business Outlook Survey conducted by its regional offices. About half of the firms surveyed reported being adversely affected, one-quarter experienced a favourable impact, and the remainder reported no effect. Jean Mair classifies and summarizes the firms' responses, identifying the sectors that were most and least affected. Causes of the impacts are identified, as well as the actions firms took as a result of the appreciation. The article looks at these actions over time to see what they tell us about firms' adjustment process.
