A thorough search of http://www.health-evidence.ca allowed us to indentify the top areas of interest to public health decision makers, and provide an overview of the availability of review-level evidence within these areas. In this paper we will not only identify topic areas of high interest to public health decision makers, we will also highlight existing gaps as well as identify topic areas with an abundance of high-quality evidence. One objective of this paper is to identify the quantity of systematic reviews available on the effectiveness of public health interventions, so as to encourage researchers and research funders to conduct/fund systematic reviews where gaps exist. A second objective is to identify the quality of systematic review evidence on the effectiveness of public health interventions in order to encourage higher quality methodological reviews and higher level synthesis of topics areas rich in high-quality reviews (e. g., review of reviews).
