Taking Part

By taking part in the Ontario Health Study, you’ll be helping to find new ways to prevent and treat major diseases like cancer, heart disease and diabetes. You’ll also help to improve the health of future generations. There are plenty of ways to participate. Read more below about our registration process and blood collection program below.

Register for the Study

The first step is to sign up and fill in our baseline questionnaire. This questionnaire will ask questions relating to your personal and family health histories, demographic information, diet, physical activity level, alcohol/tobacco use and many other factors that can help researchers study the underlying causes of chronic diseases.

Blood collection

The more information researchers have, the more questions they can answer about chronic diseases like cancer, heart disease and diabetes. That’s why we’re inviting selected participants who were between the ages of 30-74 when they completed the OHS questionnaire to also provide a blood sample. Participation will enhance the data you’ve already given and may allow you to learn something that you did not know about your health. Click here to learn more.
