Introduction: since 2000, primary care (PC) reforms have been implemented in various Canadian provinces. Emerging organizational models and policies are at various levels of implementation across jurisdictions. few cross-provincial analyses of these reforms have been realized. The aim of this study is to identify the factors that have facilitated or hindered implementation of reforms in Canadian provinces between 2000 and 2010. Methods: A literature and policy scan identified evaluation studies across Canadian jurisdictions. Experts from British Columbia, manitoba, Nova scotia, Ontario and quebec were asked to review the scope of published evaluations and draft provincial case descriptions. A one-day deliberative forum was held, bringing together researchers (n = 40) and decisionmakers (n = 20) from all the participating provinces. Results: despite a relative lack of published evaluations, our results suggest that PC reform has varied with regard to the scope and the policy levers used to implement change. some provinces implemented specific PC models, while other provinces designed overarching policies aiming at changing professional behaviour and practice. The main perceived barriers to reform were the lack of financial investment, resistance from professional associations, too overtly prescriptive approaches lacking adaptability and an overly centralized governance model. The main perceived facilitators were a strong financial commitment using various allocation and payment approaches, the cooperation of professional associations and an incremental emergent change philosophy based on a strong decentralization of decisions allowing adaptation to local circumstances. so far the most beneficial results of the reforms seem to be an increase in patients' affiliation with a usual source of care, improved experience of care by patients and a higher workforce satisfaction. Conclusion: PC reforms currently under consideration in other jurisdictions could learn from the factors identified as promoting or hindering change in the provinces that have been most proactive.
