Health-evidence.ca has nearly 5, 000 registered users, and sees over 40, 000 visitors annually representing more than 150 countries. In the development of the health-evidence.ca registry, 21 topic areas of interest to public health decision makers were identified through focus groups and consultations with key informants within the public health setting. The purpose of the registry is to facilitate access to review-level evidence for decision makers working in program planning and policymaking in public health and health promotion [19] . All reviews in the registry are indexed according to these 21 Focus of Review topic areas allowing site visitors to search the registry using common public health terms. In addition, each registered user completes a profile when signing up to the site checking off as many of the 21 topic areas relevant to them. This enables each registered user to receive a list of reviews related to their areas of interest, along with a rating of the methodological quality of each review, each quarter when the registry is updated.
