Again, from 1990 to 1992, the annual change in the CPI dropped from 5 per cent to 2 per cent. Deflation refers to a sustained fall in prices, where the annual change in the CPI is negative year after year. The best known example of deflation in Canada was during the 1930s when prices fell more than 20 per cent over a four-year period.
