An Important Notice Regarding Your Personal Health

The Ministry of Health and Long-Term Care (MOHLTC) is working with Ontario's health care providers to build a system in which your health care provider will have improved access to your personal health information including your laboratory test results.

The collection, use and disclosure of your personal health information are subject to the Personal Health Information Protection Act (PHIPA) and this notice is being issued to provide you with information to help you to decide whether or not you want to share your information. The Ministry is also subject to PHIPA.

For All Ontarians

Currently, laboratories submit your test results back to the health care provider who ordered the test(s) and any other practitioner copied on a requisition form. However, there may be several other health care providers involved in your care, who would not have access to your laboratory test information. The Ontario Laboratories Information System (OLIS) is an electronic system that will allow hospital and community laboratories to share your lab test results with health care providers, and will be a component of the Electronic Health Record.

As of mid-December 2010, the Ministry will assume custody and control of patients' laboratory test information that is submitted to and stored in OLIS. MOHLTC will then begin providing your test results to eHealth Ontario, to enable eHealth Ontario to share this information electronically with your health care providers. eHealth Ontario is the public agency that is working to deliver a secure and private electronic health care system for all Ontarians. As an agent of MOHLTC, eHealth Ontario can share this information electronically with any health care provider who delivers your health care in Ontario. MOHLTC will use and disclose your information only as permitted by law, and work to ensure that your information is secure and your privacy is respected.

Protecting Your Privacy

Your privacy is important. As a patient, you can withdraw or reinstate your consent for MOHLTC and/or health care providers who have not ordered your laboratory tests to access your laboratory test information contained in OLIS. If you choose to withdraw your consent, MOHLTC and/or health care providers who have not ordered your laboratory tests will not have access to this information through OLIS. Choosing to withdraw your consent will in no way affect your relationship with your health care provider(s), who will continue to provide care to you.

Deciding Not to Share Your Information

If you wish to withdraw or reinstate consent for MOHLTC or health care providers to access your test results submitted to OLIS, or for more information about this public notice, please call 1-800-291-1406 (TTY: 1-800-268-7095). More information about OLIS.
