What's New With the OHS?
Since 2010, the Ontario Health Study (OHS) has been working hard to build a platform for chronic disease research. Working together with the research community and Ontarians across the province we are now following the health of about 225,000 people and have collected more than 41,000 blood samples. We’re building a database of health information and a biobank so researchers can better understand the link between genetics, lifestyle and environment—and the role they play in our health.
In this section, you’ll find information about the various Study activities and upcoming initiatives.

It is with great excitement that we announce the launch of the Ontario Health Study’s Blood Collection Program! You have already made a great contribution to health research by joining the Study and completing our first online health questionnaire. Now, if you also provide a blood sample to the OHS, researchers will be able to study the information you’ve already provided in connection with your blood sample. This will give them even greater insight into the various factors that influence health and quality of life.
In order to make it possible for all OHS participants to easily provide a blood sample, we have partnered with LifeLabs® Medical Laboratory Services. This partnership makes it easy for OHS participants to visit one of LifeLabs’ 120 locations throughout the province to provide a sample at their convenience.
