Please update your contact info for the Ontario Health Study

Nov 4, 2016 // Study Updates

One of the most important challenges in a long-term study is keeping in touch with participants to collect up-to-date information. As the study continues into the future with follow-up questionnaires and other initiatives, it is important that we are able to communicate with our participants. In order to ensure we are able to reach you, we ask that you please add a contact phone number to your account.

The Ontario Health Study will continue for a long time – at least several decades. During this time it is likely that many people will move or change their email address. Though our primary method of staying in touch with you will continue to be through email, we may also contact you by phone or by mail if necessary.

How do I update my contact information?

  1. Log into your account. If you are having trouble logging in or remembering your username or password, please click here.
  2. Click “My Profile” from the main menu and then click “Personal Information.”
  3. Update your information in the fields provided and then click “Apply.”Any invalid entries will be marked in red.

How will my information be protected?

Your personal information is stored and encrypted at the same level banks use to protect online transactions. Your personal information is also stored separately from your questionnaire responses and blood sample.

If you require assistance at any point, please reach out to us by contacting a member of the team at 1-866-606-0686 or
