Suburban expansion refers to the growth of residential areas located on the outskirts of urban centers, often characterized by single-family homes, shopping centers, and various amenities. This phenomenon gained momentum in Canada during the post-World War II era as increased immigration and population growth prompted a shift in housing preferences, leading many to seek space and a better quality of life outside the congested urban environments. The rise of automobiles, improved transportation networks, and changing societal values also played crucial roles in this movement.
