What were the three most significant forces driving the social and economic changes that occurred in Canada during the 1920s?

The three most significant forces driving social and economic changes in Canada during the 1920s were industrialization, urbanization, and the impact of World War I. Industrialization led to the growth of factories and the rise of a manufacturing economy, shifting labor from agriculture to urban centers. Urbanization brought about significant demographic changes, as people migrated to cities for work, leading to new social dynamics and cultural movements. Additionally, the effects of World War I reshaped national identity and contributed to changing gender roles, as women entered the workforce in greater numbers and demanded more rights.
