The BALSAC file is under the responsibility of 4 partner universities: UQAC, Université Laval, McGill University and Université de Montréal. Under an agreement between the four institutions, UQAC is mandated for the day-to-day management of the population file, including all matters related to the protection of personal information and access to data.


BALSAC is directed by Ms. Hélène Vézina, professor in the Department of Humanities and Social Sciences at UQAC.

Hélène Vézina holds a doctorate in demography from the Université de Montréal and is a professor in the Department of Humanities and Social Sciences at the Université du Québec à Chicoutimi. Her research program addresses historical demography and population genetics issues in a multidisciplinary context. She has participated in projects on kinship, ancestral origins, fertility and longevity in the Quebec population as well as on various genetic and multifactorial diseases. She has also studied the genetic, ethnocultural and demographic diversity of Quebec's regional populations and the demohistorical factors that have helped shape this diversity. Her research is based on the exploitation of genealogical and family data from the BALSAC file, which she has been using since her doctoral thesis on the demographic and genealogical aspects of Alzheimer's disease. Since 2010, she has been leading the development and exploitation of the BALSAC population file. From 2013 to 2018, she led a project funded by the Canada Foundation for Innovation (CFI) to develop an integrated infrastructure of historical microdata on the Quebec population (IMPQ). She is currently working on a new CFI-funded initiative to create i-BALSAC, a multi-sectoral platform for leading-edge research in the biomedical and social sciences.

Interinstitutional Steering Committee

The Interinstitutional Steering Committee is based on the inter-institutional agreement that unites the 4 universities mentioned above in defining common orientations for infrastructure development and research. Founded in 2011, the committee includes a representative from each university:
– Hélène Vézina, UQAC
Marc St-Hilaire, Université Laval
Bernard Brais, McGill University
Damian Labuda, Université de Montréal

BALSAC Guidance Committee

Founded in 2020, this new committee, composed solely of UQAC professors, aims to promote the use of the BALSAC file, to encourage new collaborations and to provide avenues for the development and use of data likely to benefit the entire university community.
To date, it is composed of:
– Hélène Vézina, Department of Humanities and Social Sciences
Marie-Christine Brault, Department of Humanities and Social Sciences
François-Olivier Dorais, Department of Humanities and Social Sciences
Catherine Laprise, Department of Fundamental Sciences
Simon Girard, Department of Fundamental Sciences
Vincent Arnaud, Department of Arts and Literature
Sylvain Hallé, Department of Computer Science and Mathematics
