Discovering the Power of Mobility in Canadian Research
A groundbreaking study published today in the Journal of Evolutionary Economics has illuminated a critical dynamic in Canada's vibrant research landscape: collaborations with mobile scientists significantly enhance the scientific performance of Canadian researchers. Titled 'Scientists on the move: The impact of collaboration with different mobility groups on the performance of Canadian scientists,' this research led by Amirali Karimi, Catherine Beaudry from Polytechnique Montréal, and Vincent Larivière from the Université de Montréal, analyzes data from over 58,000 Canadian scientists.
Active researchers who began publishing since 2008 form the core sample, drawn from comprehensive Web of Science bibliometric data. The findings underscore how cross-border and domestic movements foster innovation, positioning Canada as a hub for high-impact science. This comes at a pivotal time, as Canadian universities grapple with global talent competition amid evolving funding landscapes.
The study's timing aligns with heightened discussions on bolstering Canada's research ecosystem. With universities like the University of Toronto and University of British Columbia actively recruiting international talent, these insights offer actionable guidance for fostering productive partnerships. For those exploring opportunities in Canadian academia, platforms like research jobs provide a gateway to connect with leading institutions.
Defining Researcher Mobility and Its Role in Science
Researcher mobility refers to the physical or institutional movement of scientists—such as professors, postdocs, and principal investigators—across universities, cities, provinces, or international borders throughout their careers. This phenomenon, distinct from virtual collaborations via email or video, involves relocating to new labs, departments, or countries, often driven by prestigious fellowships, grants, or career advancement opportunities.
In the Canadian context, mobility manifests in several forms: domestic shifts between institutions like McGill University and the University of Waterloo, or international relocations facilitated by programs from the Natural Sciences and Engineering Research Council of Canada (NSERC) or the Canada Research Chairs program. Mobile scientists carry with them diverse methodologies, interdisciplinary perspectives, and expansive networks, which can catalyze breakthroughs in fields ranging from artificial intelligence to climate modeling.
Historically, Canada has benefited from 'brain circulation'—a shift from one-way brain drain to cyclical talent flows. Statistics indicate Canadian researchers exhibit higher mobility rates than the global average in areas like environmental sciences, where over a notable percentage engage in international moves. This mobility not only enriches individual careers but elevates national scientific output, as measured by publication volume and citation impact.
Unpacking the Study's Rigorous Methodology
The researchers employed a novel classification system to delineate five mobility groups among collaborators: locals (stayers within Canada), immigrants (foreigners who relocated to Canada), emigrants (Canadians who moved abroad), foreigners (non-Canadian collaborators remaining abroad), and travelers (frequent cross-border movers). Classification relied on publication affiliations over time, using algorithms to detect shifts in 'mode countries'—the primary publication location—refined through multi-year windows and manual checks for accuracy.
Performance metrics were multifaceted: SumFracArt for fractional authorship contribution (accounting for team size), NbArticle for raw publication productivity, and Mean Normalized Citation Score (MNCS) for scholarly impact, normalized against field-specific expectations (MNCS=1 indicates average impact). Panel data regressions with fixed effects isolated collaboration effects, using log-transformed collaboration counts to handle skewness. Gender interactions further probed disparities, drawing from a robust sample of 58,511 scientists active through 2023.
This approach surpasses prior studies by disaggregating mobility types and focusing exclusively on Canadian-authored papers, providing granular insights into knowledge spillovers. Robustness checks via bootstrapping confirmed results across indicators.
Key Findings: Universal Boost from Diverse Collaborations
Across all performance metrics, collaborations with every mobility group yielded statistically significant positive associations. This holistic uplift demonstrates that exposure to varied experiences—whether from domestic stayers or globe-trotting travelers—amplifies output and influence.
- Contribution (SumFracArt): Strongest links with emigrants and foreigners, suggesting high-value inputs from outward and external networks.
- Productivity (NbArticle): Foreigners topped influences, likely due to sparking prolific co-authorships.
- Impact (MNCS): Immigrants led, bringing novel ideas that resonate globally.
These patterns align with broader literature, where mobile researchers historically garner up to 17% more citations through enhanced networks. In Canada, where higher education research and development (HERD) spending constitutes a key R&D pillar, such collaborations could propel universities toward top global rankings.
Spotlight on Specific Mobility Groups' Contributions
Delving deeper, emigrants—Canadian scientists abroad—excel in boosting fractional contributions, perhaps by maintaining strong ties and facilitating reverse knowledge flows. Foreigners, collaborating remotely from overseas institutions, drive publication volume, indicative of efficient, high-output partnerships without relocation costs.
Immigrants, integral to Canada's multicultural research fabric, uniquely elevate citation impact, their cross-cultural insights yielding field-transcending papers. Travelers, the most dynamic group, contribute broadly, embodying 'brain circulation' that enriches all metrics. Even locals provide stability, enhancing productivity through reliable domestic teamwork.
Visualizations from the study (e.g., Figures 1-6) map these groups' prevalence in Canada's research landscape, highlighting concentrations in STEM fields at institutions like the University of Alberta and Simon Fraser University.

Gender Dynamics: Amplified Benefits for Women Researchers
A striking revelation: female Canadian researchers experience magnified gains from certain collaborations. Interactions with immigrants boost both contribution and impact more for women, while local peers enhance productivity. This suggests mobility partnerships help mitigate gender gaps in citations and output, prevalent in Canadian academia.
Policy-wise, this advocates targeted networking for women, aligning with Canada Research Chairs' equity initiatives. Universities can leverage this by prioritizing inclusive mobility programs, fostering equity in higher ed careers.
Canada's Strategic Initiatives to Harness Global Talent
Echoing the study's implications, the Government of Canada launched the $1.7 billion Canada Global Impact+ Research Talent Initiative in December 2025. This tri-agency program targets over 1,000 elite researchers in AI, biotech, clean tech, and more, offering chairs worth $4-8 million over eight years.Learn more on the official site
Aimed at early-career and senior talent, it streamlines immigration and funds infrastructure, directly addressing mobility barriers. Universities nationwide, from Dalhousie to UBC, stand to benefit, amplifying performance as per the new study.
Real-World Case Studies from Canadian Universities
At Polytechnique Montréal, lead authors' home, international hires in engineering have spiked citation rates, mirroring study findings. Similarly, the Université de Montréal's Observatoire des Sciences et des Technologies exemplifies immigrant-led bibliometric advances.
The University of Waterloo's quantum computing collaborations with emigrants abroad have yielded high-MNCS papers, while McMaster University's health researchers benefit from foreigner partnerships. These cases illustrate practical uplifts: one Waterloo team reported 25% productivity gains post-mobility hires. For aspiring researchers, postdoc positions often serve as mobility entry points.
Challenges Facing Researcher Mobility in Canada
Despite benefits, hurdles persist: visa delays, funding instability, and family relocation costs deter moves. Provincial disparities—Ontario and Quebec lead in HERD spending—exacerbate uneven access. Gender and equity barriers further complicate flows, as noted in the study.
- Spousal employment: Key for dual-career scientists.
- Grant portability: NSERC enhancements needed.
- Cultural integration: Mentorship programs vital.
Addressing these ensures sustained performance gains.
