Migrant Brokers: How Nigerian Health Workers in Canada Shape Migration Back Home

When a nurse in Lagos texts a former colleague now working in a Canadian hospital, the exchange is more than a catch-up between friends. It is a transaction in one of the most consequential currencies of the global health workforce: information about whether, and how, to leave. A new study by sociologist Sheri Adekola of the University of Guelph, published in Discover Social Science and Health, examines precisely these exchanges, tracing how Nigerian health workers who have settled in Canada act as information brokers for professional contacts who remain in Nigeria. The research, supported by the Social Sciences and Humanities Research Council of Canada and approved by the Wilfrid Laurier University Research Ethics Board, draws on bilateral survey and interview data from 59 Nigerian health workers residing in Canada and 63 non-migrant health professionals in Nigeria, offering a rare paired view of both ends of the same migration corridor.

The theoretical starting point is transnationalism, the idea that migrants do not simply cut ties with their countries of origin but remain embedded in cross-border networks of money, obligation, communication and care. Migration scholars have long argued that this continued engagement does something more than sustain family bonds: it reproduces migration itself. When migrants send remittances, share photographs of new homes, or describe their working conditions, they signal to non-migrants that emigration is feasible and beneficial. Adekola’s study tests this claim empirically in a corridor where the stakes are unusually high. Nigeria’s health system has been visibly strained by the emigration of physicians, nurses and other professionals, a phenomenon so widespread in popular discourse that it has acquired its own vernacular label, and destination countries such as Canada actively recruit internationally educated health workers to fill persistent labour shortages.

The survey results document just how intensely the Nigerian migrants in Canada remain plugged into their home networks. Across four domains of transnational activity, engagement levels were strikingly high. Some 88.1 percent of the Canadian-based respondents reported participation in social transnational activities, such as regular communication, family obligations and community ties spanning the two countries. Knowledge transfer activities, including professional advice and the sharing of expertise, were reported by 83.1 percent. Credential acquisition, meaning the pursuit of Canadian qualifications, licences or certifications that anchor professional integration, stood at 76.3 percent, while economic activities such as remittances and investments reached 74.6 percent. The one clear outlier was political participation, reported by only 10.2 percent of respondents, suggesting that the transnational lives of these health workers are organized around family, profession and finance rather than formal politics.

The brokerage hypothesis at the heart of the study found direct support in the survey data. Migrants who participated in transnational activities were more frequently approached by contacts in Nigeria for migration advice, and 75 percent of the Canadian respondents reported receiving such inquiries. In other words, the density of a migrant’s cross-border engagement appears to translate into their visibility and availability as a source of migration knowledge. This is the mechanism the study names transnational information brokerage: the practice by which migrants contextualize, filter and communicate migration knowledge within their networks. The concept matters because migration decisions are not made in an informational vacuum. Aspiring migrants must interpret visa rules, credential recognition requirements, licensing examinations, labour market conditions and the lived realities of working in a foreign health system, and brokers are the people who translate that complexity into actionable guidance.

Yet the study’s most provocative finding complicates the simple story in which migrant brokers drive migration chains forward. On the Nigerian side, 81 percent of the health professionals surveyed expressed migration intentions, confirming that the aspiration to leave is nearly universal in this population. But only 39 percent had actually sought information from migrants abroad. That gap between aspiration and brokerage is the analytical pivot of the paper. If transnational engagement reliably seeds migration intentions, one might expect the majority of aspiring migrants to be tapping their diasporic contacts for advice. Instead, most were not, and when respondents explained their preference for Canada as a destination, they attributed it to institutional information channels rather than personal networks, citing immigration promotion and media narratives as the sources that had shaped their views.

This asymmetry carries real consequences for how migration systems work. If the dominant images of Canada circulating among Nigerian health professionals come from official promotion and media coverage rather than from people who have made the journey, then the information underpinning one of the world’s most significant health worker flows is systematically incomplete. Institutional channels have incentives to emphasize opportunity; media narratives tend to compress complex experiences into success stories. What they rarely convey is the granular, often difficult middle ground of the migration experience: the years spent re-qualifying, the credential recognition hurdles, the licensing examinations, the experience of being internationally educated in a destination health system that treats foreign training unevenly. These are precisely the domains in which migrant brokers possess knowledge that no website or advertisement can replicate.

The study’s findings suggest, moreover, that migrant advice may cut in both directions. A broker who has struggled through credential recognition, worked below their qualification level, or watched colleagues burn out in an unfamiliar system may counsel caution, delay or alternative pathways as readily as encouragement. Brokerage, in this reading, is not a one-way amplifier of migration but a moderating influence that can temper aspirations with realism. That possibility reframes the classic image of migration chains, in which each successful pioneer pulls the next cohort along. Chains may also include brakes, exercised by migrants whose transnational position gives them both the credibility and the motivation to tell aspiring migrants what the institutional channels leave out.

The analysis also speaks to a broader question of health equity that extends well beyond the Nigeria-Canada corridor. Adekola argues that access to professional integration within destination health systems is mediated by informational asymmetries, meaning that the migrants who succeed fastest are often those with the best access to accurate, insider knowledge about how credential recognition and labour market entry actually work. Health workers without well-placed brokers must navigate the same systems with less information, facing longer delays, costlier detours and a higher risk of de-skilling. Within the global migration system, then, information functions as a stratifying resource. Two nurses with identical qualifications and identical determination may experience radically different integration trajectories depending on whether someone in their network has already mapped the terrain.

The policy implications follow directly. Migration governance structures and credential recognition processes are not merely administrative machinery; they shape, and are shaped by, the flows of knowledge that move through migrant networks. For destination countries concerned with the fair integration of internationally educated health professionals, the findings suggest that transparency and accessible information about recognition pathways could reduce the dependence on informal brokerage and level the playing field for candidates without diasporic connections. For origin countries watching their health workforce drain away, the study suggests that interventions aimed at retention cannot ignore the informational infrastructure of migration, because aspiration in this population is nearly universal while the moderating voice of experienced migrants reaches only a minority of those contemplating departure.

What emerges from the study is a picture of migration decision-making as a negotiated, networked process rather than an individual calculation. Nigerian health workers in Canada remain deeply engaged across economic, social, professional and credential-related dimensions of transnational life, and that engagement makes them sought-after advisers. But the aspirations of their Nigerian counterparts are formed substantially before those conversations happen, shaped by immigration promotion and media narratives that paint destination countries in broad, optimistic strokes. The brokers then enter a system already tilted toward departure, and their influence may be to refine, redirect or occasionally discourage rather than to initiate. Understanding health worker migration, the study implies, requires attending not just to who moves and why, but to who knows what, who tells whom, and how the knowledge that circulates between Lagos and Toronto is produced, filtered and believed.
