The purpose of the CAMH's Provincial System Support Program (PSSP) is to create and build the implementation capacity of regional and local Implementation Teams. Using Active Implementation frameworks, NIRN is supporting CAMH to develop the infrastructure for sustaining and scaling interventions in children’s mental health and addiction sectors across the Province. NIRN staff will provide Implementation Science expertise and serve as consultants to assess current “systems”, provide recommendations for building capacity, create opportunities to apply principles of implementation science, and support leadership and build implementation capacity of Service Collaboratives.
