It is often argued that countries hosting large populations of skilled immigrants might benefit from their cultural and economic competencies in the development of international trade networks. Yet, in so doing, the state can be criticized for fetishizing the ethnic immigrant in market terms in order to extract ‘ethnic surplus value’. In this article, I examine these debates empirically in the case of India–Canada immigration and trade using interviews with traders, officials and immigrant entrepreneurs in British Columbia, Canada. Findings suggest that the supposedly positive relationship between trade and immigration is not obvious in the India–Canada case and there is no convincing evidence of the state managing successfully to extract ‘ethnic surplus value’. Rather, what appears most compelling is evidence of what can be termed a discourse of regional disadvantage circulated by immigrant and non‐immigrant business actors alike regarding the nature of India–Canada relations. Interview respondents link this discourse of disadvantage to the regional history of Indian immigration to Canada, which has traditionally comprised Sikhs from rural Punjab, and it functions to essentialize Indian immigrant ethnicity spatially within both the Indian and Canadian contexts. I focus on the theme of the extraction of ‘ethnic surplus value’ and regional disadvantage to reveal the limitations of both arguments about the economic nature of immigrant‐led network development. In both cases, I challenge these ideas with a critical emphasis on the role of immigrant agency and offer a more nuanced and complicated reading of the role of the state. As a result, I offer a detailed reading of how socio‐spatial immigrant networks are formed and operate at the regional scale, and how this complicates more abstract theoretical formulations regarding the trade and immigration nexus.
