COVID-19 Testing

Information for all

Effective September 24, 2020: Ontarians should only seek testing at assessment centres if you are:

  • Showing COVID-19 symptoms;
  • Have been exposed to a confirmed case of the virus, as informed by your public health unit or exposure notification through the COVID Alert app;
  • A resident or work in a setting that has a COVID-19 outbreak, as identified and informed by your local public health unit; and
  • Eligible for testing as part of a targeted testing initiative directed by the Ministry of Health or the Ministry of Long-Term Care.

Please go to the Region of Waterloo Public Health website for more information about COVID-19 symptoms, and complete the self-assessment tool. Click here for the link [opens a new window]. If you are unable to leave your home for testing due to a medical condition, speak to your health care provider or call an assessment centre.

All patients with positive results will be contacted by Public Health, otherwise please follow up with your family physician.

When will I get my results? We are starting to increase the number of swabs we can process in our own hospital lab and some of our testing is reported in less than 24 hours. Most tests (approximately 85%) are completed within 48 hours, however it can take up to 72-96 hours depending on the volume of tests that need to be completed.
