Migration influx has helped countries like Canada, Australia, and the UK balance aging populations and falling birth rates. Migration fills labour shortages, with the US thriving due to a growing labour pool, albeit on a smaller scale than Canada. However, despite population growth, living conditions in Canada are worsening due to high housing costs and limited job opportunities, leading to a per-capita GDP decline. This has prompted Canada to reduce immigration targets. These factors have led to calls for stricter immigration controls and housing reforms. Despite these issues, immigration remains vital for economic growth, necessitating balanced government policies.
