The impact of World War II on Vancouver was both positive and negative. On one hand, the establishment of military bases and the influx of war-related industries brought in jobs and economic growth to the city. On the other hand, this came at the cost of civil liberties as the government implemented restrictive measures such as censorship and internment of Japanese Canadians. The war also had an impact on the social fabric of the city, as the influx of soldiers and war-industry workers led to housing shortages and increased racial tensions. The war-related industries also brought in new technologies but also left behind a significant environmental impact on the city, as the shipbuilding yards and aircraft manufacturing plants caused pollution and contamination in the areas where they were located.
