CFIB’s Business Barometer tracks small business confidence, expectations and operating conditions in Canada. It was revised as of the May 2009 issue. It is based on the same survey question on 12-month future business performance expectations collected annually 1987-2000, quarterly 2001-2008 and monthly since late 2008. The index is a weighted average of response scores: 100 for stronger performance, 50 for same performance, and 0 for weaker performance. The data are not seasonally adjusted.
