Toronto Public Health (TPH) is responsible for assessing the health of Toronto’s population by measuring, monitoring, and reporting health determinants and risks, health outcomes and related health inequities.

The Rapid Risk Factor Surveillance System (RRFSS) supports this mandate by providing timely, local data on the health of Toronto residents. The RRFSS is a voluntary telephone survey that includes questions about chronic diseases, nutrition, physical activity, tobacco use and other health issues.

In 2016, a random sample of about 2,400 Toronto residents 18 years and older were included. In 2017, about 1,800 Torontonians were interviewed. In 2018, about 1,800 will be included in the survey.

RRFS is conducted by the Institute for Social Research (ISR) at York University on behalf of TPH and other areas of Ontario. ISR has extensive expertise in survey research.
