The transfer of the laboratories from the Ministry of Health and Long-Term Care to PHO in December 2008 and the relocation of the laboratory are key aspects of the province’s multi-year plan to renew the province’s public health system. The decision to move the Toronto laboratory was made in 2006, prior to the establishment of PHO, in response to the recommendations of several post-SARS inquiries and expert panels.

Other renewal efforts began in 2007 within government and continued within PHO to achieve operational efficiencies, faster turnaround times and increase scientific and technical expertise, and implement new laboratory platforms and technologies. This means that health care providers have timely clinical results to inform patient care and that public health organizations have improved ability to monitor, detect and manage public health issues.

The new laboratory will replace the aging and inadequate Etobicoke facility with a purpose-built, highly specialized and flexible space designed to meet current and future clinical and public health needs, support a more integrated approach to diagnostic, outbreak and incident management, and enable faster turnaround times for test results.

The move will enable Public Health Ontario to remain at the forefront of infectious disease detection and control, providing essential services to Ontarians and the health care system and responding to emerging public health issues.  The relocation will also strengthen PHO’s links to academic, health care and private sector partners, fostering more collaborative research, practice and knowledge exchange with the world-class health research community situated in and around the Discovery District.

​New lab to serve as Ontario’s central infectious disease testing and reference facility

The new laboratory has been designed and is being built in accordance with Canadian Biosafety Standards and Guidelines, is now underway. It will be certified to ensure it meets or exceeds operating standards and guidelines established by the Public Health Agency of Canada and the Canadian Food Inspection Agency, in addition to Ontario Laboratory Accreditation standards.

We consistently earn high ratings for quality, safety and accreditation, and are committed to ensuring laboratory staff, visitors, other building occupants, the public and the environment are safe.
