With approximately 50,000 children and youth younger than 15 years of age immigrating to Canada annually (2), not to mention the children born in Canada to immigrant/refugee families within their first decade of living in this country, the importance of understanding these intricacies and challenges becomes even more acute. We highlighted the need to understand both the official definitions of status, or lack thereof, for families and children new to Canada (3) (which can have implications for the type of health care services that individuals may or may not qualify for) as well as the unique backgrounds, cultures, migration stories, belief/ support systems, positive/negative experiences and health perceptions that can greatly impact each child’s physical and mental health and well-being. In our previous commentary, we also briefly touched on the importance of migration process factors (4), immigrant-specific factors (eg, the ‘healthy immigrant effect’, ‘resettlement stress’ and ‘convergence effect’, among others) (5-7), and the social determinants of health (8) (Box 1) including the disproportionate role that they have in the health of children and youth new to Canada. As stated in a previous commentary (9): Anyone who has worked with an immigrant child and family, be it in an office, emergency room, home visit, school meeting, or elsewhere, can relate to the sense of frustration at knowing or at least feeling that there are barriers and challenges that we could do a better job of alleviating.
