By bundling services and encouraging interprofessional and interorganizational collaboration, integrated health care models counter fragmented health care delivery and rising system costs. Building on a policy impetus toward integration, the Ministry of Health and Long‐Term Care in the Canadian province of Ontario chose 6 programs, each comprising multiple hospital and community partners, to implement bundled care, also referred to as integrated‐funding models. While research has been conducted on the facilitators and challenges of integration, there is less known about how integration is generated. This article explores the generation of integration through the dynamic interplay of contexts and mechanisms and of structures and subjects.
