At the Ontario Centre of Excellence for Child and Youth Mental Health (the Centre), our focus is on building community-based agencies’ capacity for evaluation within the context of evidence-informed practices. The Centre provides funding, support and training to enhance agencies’ evaluation skills and knowledge, and has developed a number of evaluation resources including this toolkit as additional learning tools. Through these resources and activities, the Centre aims to advance the implementation of evidence-informed practices for the optimum delivery of child and youth mental health services.
