International migrant workers play an increasingly important role in the global economy and labor markets. As of 2017, there were 164 million migrant workers around the world, representing 4.7% of all workers. Although found in a variety of sectors, both the Global North and South rely heavily on migrant agricultural workers to fulfill domestic labor shortages in the agricultural sector. This paper explores migrant agricultural worker policies and demand in Thailand, Italy, and Canada and compares the policy responses to COVID-19 and the subsequent treatment of migrant agricultural workers in these three countries. Using the documentary method, we first develop detailed cases of each country’s migrant agricultural worker policies, demand, and response to COVID-19. Then a comparative analysis is conducted between Thailand, Italy, and Canada to identify emerging themes in policy, COVID responses, and migrant agricultural worker treatment. Despite the critical importance of migrant agricultural workers to each country to agricultural economies and food security, many workers still face policy challenges and mistreatment that were exacerbated by COVID-19. This work highlights the need for governments and policymakers to create new inclusive policies that guarantee improved labor, health, and safety standards and quality of living for all migrant agricultural workers, guaranteeing their basic human rights.
