This article evaluates the role civil society organizations play in helping noncitizen migrant workers access to social rights in Canada. The study focuses on the bilateral Canadian Seasonal Agricultural Workers Program, a temporary worker scheme that brings Mexicans to Canada to work as harvesters for a four‐to‐eight‐month period. Despite the common description of this program as “best practice,” questions are raised about the ability of workers to access citizenship rights and even limited labor protections. We draw on primary field research conducted in the province of Ontario's agricultural sector to consider how involvement of civil society state actors operating at a variety of scales—local, national, international, and the extra territorial—in a range of social justice struggles expands access to social citizenship rights for Mexican migrant workers.
