An ever-greater proportion of immigrants to Canada are from countries in the Global South, including Africa. The Southern African diaspora in Canada, the focus of this special report, currently exceeds 120,000 people and continues to grow. Guided by the new consensus that migration is, or can be, good for development, given that migrants from the South to the North rarely cut their ties when they emigrate, the authors of this report, led by Jonathan Crush, CIGI Chair in Global Migration and Development, provide a systematic knowledge base about the Southern African diasporas in Canada, insights about the actual and potential development impacts of these diasporas, and a new methodology for accessing information about diasporas.
