Migration has become a defining feature of contemporary global dynamics, propelled by the accelerating forces of economic globalization and transnationalism. According to the United Nations Department of Economic and Social Affairs (UN DESA, 2025), an estimated 304 million individuals were international migrants by the end of 2024, with approximately 65% migrating from the Global South to the Global North. This increasing trend is largely driven by the demand in countries in Global North for highly educated and skilled workers to address demographic challenges such as ageing populations, labor shortages, and the transition to knowledge-based economies. Beyond these economic drivers, migration is further shaped by demographic transformations and the growing ethnic and racial diversity in host countries, adding complexity to integration processes. Canada, a country fundamentally shaped by immigration, has significantly restructured its immigration policies to emphasize human capital attributes such as education, skills, and language proficiency. While these policy changes have enabled greater access for skilled immigrants from across the globe, persistent systemic barriers continue to impede their full employment integration. Many skilled immigrants remain underemployed or work in positions that do not align with their qualifications. This chapter introduces the book’s central focus: the paradox of skilled immigration in Canada, wherein immigrants are integral to economic development yet face disproportionate underemployment. It also outlines the book’s objectives, demographic profile of immigrant populations, research site, and a summary of the chapters that follow.
