While interest in youth aging out of substitute care has translated into a growing number of scientific publications across the world, it is still difficult to estimate the Canadian contribution to this research field. A scoping review was undertaken to provide a comprehensive overview of the scientific literature on aging out of substitute care in Canada. Results reveal a number of notable trends, research gaps and future avenues to uncover areas where more research is needed. The discussion highlights the relevance of integrating previous findings into new research activity and provides recommendations to build a more cohesive knowledge base.
