New research from Statistics Canada’s Longitudinal Immigration Database reveals a nuanced picture: while fewer foreign postdoctoral fellows are arriving in Canada and fewer are staying permanently, those who do obtain permanent residency earn significantly more than other immigrant groups. Inflows have declined since 2021, permanent residency conversion rates dropped from 28% to 22% across successive cohorts, and long-term active presence is declining yet among those who stay, earnings outpace virtually every comparable immigrant group.
Who are Foreign Postdoctoral Fellows and Why Do They Matter for Canada?
Foreign postdoctoral fellows are highly trained researchers typically holding a PhD or nearing its completion who accept fixed-term appointments at Canadian universities and research institutions. They lead independent projects, collaborate across disciplines, support graduate training, and drive much of Canada’s scientific publishing and innovation output.
They arrive in Canada under the International Mobility Program (IMP), using a Labour Market Impact Assessment (LMIA) exemption code (C44) specifically for postdoctoral appointments. To qualify, a foreign national must be appointed to a time-limited position in a field related to their PhD, be receiving a stipend or salary, and be selected on the basis of academic excellence.
For Canada, attracting postdoctoral talent is a strategic investment. These individuals fill a critical role in sustaining the productivity of research institutions and advancing scientific knowledge in areas ranging from medicine to artificial intelligence to clean energy.
Are Fewer Postdoctoral Fellows Coming to Canada?
The short answer is yes and the trend is worth understanding in context. In the 2000s and 2010s, between 2,100 and 3,400 foreign postdoctoral fellows entered Canada annually. After a sharp COVID-19-related dip in 2020 and a partial recovery in 2021, inflows fell to levels below even the early 2000s by 2024. That decline stands out against the broader trend in temporary foreign workers, whose numbers have grown substantially over the same period.
As a result, foreign postdoctoral fellows now make up roughly 0.3% of all temporary work permit holders down from about 3% in the early 2000s. The ratio of postdoctoral fellows to Canadian-educated PhD graduates has also fallen, from 0.44 in 2010 to 0.25 in 2023.
The composition of postdoctoral fellows has changed too. Eastern Asia and Northern and Western Europe were historically the dominant source regions but their combined share dropped from 57% in 2000–2004 to 40% in 2020–2024. Meanwhile, more researchers are arriving from Southern Asia, Africa, Latin America, and the United States. The gender gap is also narrowing men represented 70% of the 2000–2004 cohort, dropping to 60% in the most recent cohort.

How Many Postdoctoral Fellows Stay in Canada Permanently?
This is one of the more striking findings. Across the cohorts studied, only about one in four postdoctoral fellows transitions to Canadian permanent residency within ten years of first arriving.
Specifically, 28% of those who arrived between 2000 and 2004 had obtained permanent residency within a decade. That rate dropped to 26% for the 2005–2009 cohort and 22% for the 2010–2014 cohort. And for the two earliest cohorts where even longer tracking is available, the rate barely moved beyond year ten.
Compared to other temporary foreign workers, this is a relatively modest retention rate. Among workers admitted through the Temporary Foreign Worker Program, 10-year permanent residency rates rose to nearly 49% for the 2010–2014 cohort more than double the postdoctoral rate. But here’s the important nuance: lower retention doesn’t necessarily mean failure. Postdoctoral researchers operate in globally connected labour markets where international mobility is the norm, not the exception. Many return home, move to another country, or take up academic positions elsewhere after their Canadian appointment concludes. That’s not brain drain — it’s brain circulation, and Canada participates in it as both a sender and receiver of talent.
Do Those Who Stay Actually Do Well in Canada?
The earnings data makes a compelling case. Among former postdoctoral fellows who remained in Canada and were actively working after obtaining permanent residency, earnings outperformed every other immigrant comparison group by a wide margin.
In the first full calendar year after gaining permanent residency, former postdoctoral fellows earned approximately 15% more than other IMP work permit holders and about 20% more than former TFWP workers in observed earnings. Those gaps widened over time. By year eight, postdoctoral fellows earned roughly 31% more than other IMP participants. By year ten, they earned over 51% more than former TFWP workers. Compared to immigrants who arrived directly as permanent residents, former postdoctoral fellows earned roughly twice as much even after adjusting for demographic differences.
These are not small differences. They speak to the high earning potential of PhD-level professionals who have built networks and expertise within Canadian research systems and then transitioned into the broader labour market.
What About Long-Term Presence in Canada?
Even among those who obtain permanent residency, active presence in Canada gradually declines. The proxy used in this research is income tax-filing, a reasonable indicator of whether someone is living and working in Canada in a given year.
About 86% to 89% of former postdoctoral fellows filed taxes in their first full year after admission. By year five, that dropped to 78% to 82%. By year ten, it fell further to 69% to 74%. These rates are lower than other immigrant groups. Former TFWP participants, for comparison, showed a 10-year tax-filing rate of 85% to 91%.
Again, context matters. Postdoctoral careers are internationally mobile by design. A former postdoctoral fellow who spends several years in Canada, earns permanent residency, and then takes a faculty position at an international university hasn’t failed the system, they’ve followed the typical arc of an academic research career.
What Does This Mean for Canada’s Immigration and Research Policy?
The findings carry real implications for how Canada thinks about postdoctoral talent. If retention is the only metric that matters, the picture looks disappointing. But if Canada considers the full contribution the research output, the graduate students trained, the publications, the economic earnings of those who stay, a more positive picture emerges.
From a policy standpoint, this study suggests that immigration and research frameworks should support flexibility. Not every postdoctoral fellow will stay permanently, and designing policy around that assumption may miss the point. What matters is making Canada attractive enough to draw the best researchers, giving them pathways to permanent residency if they choose to stay, and allowing the research ecosystem to benefit from their presence however long or short that may be.
For foreign postdoctoral fellows themselves, understanding the Canadian immigration landscape, including Express Entry, the Canadian Experience Class, and Provincial Nominee Programs is essential for those who do wish to build a long-term future in Canada.
One of our clients a biomedical researcher from India who completed a postdoctoral fellowship at a Toronto-area university came to ImmigCanada after his two-year appointment concluded. He had strong Canadian work experience, published research, and a solid language profile, but wasn’t sure how to translate that into a PR application.
His CRS score was 468. With guidance from RCIC Eivy Joy Quito, he enrolled in the Canadian Experience Class stream of Express Entry, improved his French language skills to gain bonus CRS points, and received an ITA within four months. His application was approved without any requests for additional information.
He now works as a senior research scientist at a Canadian biotech firm, earning well above the national median for his field, consistent with what the Statistics Canada data shows for postdoctoral fellows who stay.
Frequently Asked Questions
A: Yes. Postdoctoral fellows who gain Canadian work experience through their fellowship can apply through Express Entry’s Canadian Experience Class, the Federal Skilled Worker stream, or a Provincial Nominee Program, depending on their qualifications.
A: Foreign postdoctoral fellows typically work under the International Mobility Program (IMP) using LMIA exemption code C44. This permit is employer-specific and tied to the sponsoring institution.
A: Several factors contribute, increasing academic opportunities in source countries (especially China), precarious employment conditions in academia, and limited career progression pathways. However, the internationally mobile nature of postdoctoral careers is also a major factor: many researchers follow global opportunities rather than settling in one country long-term.
A: Yes. The data shows that former postdoctoral fellows who remain in Canada earn substantially more than other immigrant groups in some cases nearly twice as much as directly admitted permanent residents, even after controlling for demographic differences.
A: Generally yes, if the role falls under a NOC code recognized by Express Entry. The specific NOC classification depends on the nature of the work. An RCIC can help assess your eligibility.
A: Options include Express Entry (CEC or FSW streams), Provincial Nominee Programs, or in some cases, employer-specific work permits leading to a PR application. The right pathway depends on your occupation, experience, and provincial connections.
Your Path to Permanent Residency Is Closer Than You Think
