He is also a research member of McGill University’s Centre for Research on Children and the Centre de recherche et d’expertise Jeunes en difficulté, board member of the Canadian Child Welfare League of Canada and Associate Editor of Child Abuse and Neglect. Based in Montreal, Tonino and his CRC team are focused on better understanding the implications of using administrative data in longitudinal studies to better inform child welfare practice and policy. Specifically, Tonino and his CRC team seek to understand the broader systemic, socioeconomic, and neighbourhood factors that keep children chronically involved in child welfare and negatively impact parental capacity. Many of his CRC lead projects consider the trajectories and outcomes of children involved with child welfare as well as the influences of social spending, socioeconomic vulnerabilities, and neighbourhood-level services on children and families.
