C.D, Howe Intitute's Business Cycle Council classifies Canada's recession according to their severity, with Category 4 recessions being the second highest after Category 5, which is a depression. It defines Category 4 recessions as having substantial declines in real GDP and employment for a year or longer. The early 1990s recession in Canada is classified as a Category 4 recession, the same category as the early 1980s recession. Notably, the early 1990s recession did not have as deep a contraction as the early 1980s recession, but was of longer duration as it had four years of less than 2.3% growth in real GDP (1989-92), while the early 1980s recession only had two years of less than 2.3% growth (1980 and 1982), and only the early 1990s recession actually saw a decrease in GDP per capita, that being by $29 in 1991. Both recessions had high unemployment after the recessionary period had officially ended with unemployment rates of 12% and 11.4%, in 1983 and 1993, respectively. Other sources describe the early 1990s recession as "the deepest in Canada since the Great Depression of the 1930s" naming it "the Great Canadian Slump of 1990-92."
