Why is 1930's a significant year to canada

Canada was hit hard by the Great Depression. Between 1929 and 1939, the gross national product dropped 40% (compared to 37% in the US). Unemployment reached 27% at the depth of the Depression in 1933. Many businesses closed, as corporate profits of $396 million in 1929 turned into losses of $98 million in 1933. Families saw most or all of their assets disappear and their debts became heavier as prices fell. Canadian exports shrank by 50% from 1929 to 1933. Worst hit were areas dependent on primary industries such as farming, mining and logging, as prices fell and there were few alternative jobs.
