The 2018 survey asks Canadians questions about awareness, knowledge, attitudes, and behaviours related to Sexually Transmitted and Blood-Borne Infections (STBBI). To some extent, the survey builds on previous surveys commissioned by the Public Health Agency of Canada in 2003, 2006, and 2012, although most of the current survey has been redesigned to align with current program objectives. Evidence gathered through this survey is intended to enhance the capacity of all players to contribute to reduce the health impact of STBBI in Canada by 2030.
