The Ontario Chronic Disease Prevention Alliance (OCDPA) was officially formed in February 2003 to address the urgent need for integrated action and collaboration on the issue of chronic disease prevention. Since its formation, the Alliance has provided overviews on the determinants and risk factors for chronic disease development; addressed the economic cost of chronic disease in Canada; and identified the priorities of action in chronic disease prevention.
