Broker organizations were identified as pivotal for ensuring connections among network members, for supporting immigrant family access to services through their involvement with multiple providers, and for developing cultural competence capacities in the system overall. Network cohesiveness differed depending on the type of need being addressed, as did the organizations playing the role of broker. Service providers were able to extend their reach through the co-location of services in local centres and schools attended by immigrant families and their children. The study demonstrates the value of ties across service sectors facilitated by broker organizations to ensure the delivery of comprehensive services to young immigrant families challenged by an unfamiliar system of care.
