Secondary suites have existed in Canada since the 19th century where they took the form of coach houses, servant houses, stabled converted to permanent apartments, and small apartments for young people within large houses. Secondary suites became increasing popular during the economic crisis of 1929 and the housing shortage following WWII. During this period the Canadian government actively supported the creation of secondary suites. However, suburbanization and zoning changes in the 1950s and 60s led to a decrease in secondary suites in Canada. More recently, secondary suites are increasing in popularity and many municipalities are reexamining their regulations to support secondary suites.
