Waterloo Region COVID-19 Summary


Region of Waterloo Public Health continues to work closely with local hospitals, health care partners, the Ministry of Health, Public Health Ontario and many community partners to respond to Novel Coronavirus (COVID-19) in Waterloo Region.

Cases in Waterloo Region

Due to changes in testing availability as a result of increasing case volumes, case counts on our dashboard are an underestimate of the true number of individuals with COVID-19 in Waterloo Region. As such, data should be interpreted with caution.

The COVID-19 data results presented below represent a snapshot of the cumulative totals at the time of reporting. The results will differ each day as new case information is available and the situation continues to change. We expect to update case information Monday to Friday at 1:30 p.m. with data that are current as of 11:59 p.m. the previous day(s). Data on test counts are refreshed on Tuesdays and Fridays. For updates on weekends and statutory holidays, check All Ontario: Case numbers and spread on the Provincial website.

  • There are two date options for the epidemiological curve also known as an "epi-curve" graphs:
    • By episode date: The epi-curve by ‘episode date’ shows a more accurate picture of the progression of the epidemic over time. Caution is needed when interpreting the most recent results, because there is a one to two week lag from when individuals get sick, to when cases are reported to Public Health.
    • By case reported date: The epi-curve by ‘case reported date’ shows the number of cases over time as they were reported to Public Health.

Map - neighbourhood data

  • Cases and rates by municipality and neighbourhood are based on home residence of positive cases (usually the address found on an individual’s health card or their normal place of residence) and does not necessarily reflect where exposure occurred.
  • NR = 'not reportable'; neighbourhoods with counts less than or equal to five cases have been suppressed to protect personal health information.
  • The number of positive cases in each municipality and neighbourhood is skewed based on testing guidance that prioritizes groups and settings at greater risk, including long-term care and retirement homes.
  • There is broad circulation of COVID-19 in our community. It should be assumed that you could get COVID-19 anywhere in Waterloo Region.
