Reportable Diseases Toolkit

Ontario health care providers are required to report any suspect or confirmed reportable diseases or their etiologic agents as per Ontario Regs 559/91 and amendments under the Health Protection and Promotion Act (HPPA). Download a printable list: Printable Reportable Disease List (current as of October 2017).

Some of the diseases must be reported immediately due to the need for public health follow-up. The remaining diseases can be reported as soon as possible and at least by the next working day. The diseases which require IMMEDIATE reporting are marked with an * on the Printable Reportable Disease List (current as of October 2017). Patient consent is not required for reporting this information. The Personal Health Information Protection Act (PHIPA) explicitly allows health care providers to disclose information to the local Medical Officer of Health for purposes outlined under the HPPA.



A reportable diseases toolkit for health care providers has been adapted with permission from the Leeds, Grenville and Lanark District Health Unit. Each of the diseases is listed in the navigation menu on the left-hand side of the page (or below on a mobile device).

The goal of this toolkit is to improve accessibility to credible and up-to-date information on Ontario’s reportable diseases in a format that is quick and easy to use, all in one location.

The information available for each disease includes reporting requirements, epidemiology, risk factors, diagnosis and testing, treatment and case management (if applicable), patient fact sheet, and additional resources with links attached.
