COVID-19 alert levels

The alert levels tell us all what public health measures need to be taken. Until there is a vaccine, community public health measures should be followed to help stop the spread of COVID-19.

Public Health phases and triggers

The phased plan will allow health experts to monitor and evaluate the impact of the lifting of restrictions. At any time, restrictions that have been lifted may quickly be reinstated to protect public health. Restrictions may be put in place based on provincial, regional or local circumstances such as unlinked community outbreaks or cases that cannot be traced. If required, a zone could move more than one alert level at a time (e.g. Yellow Alert Level to Red Alert Level or Yellow Alert Level to Lockdown).

Risk assessments are triggered if the following occurs:

  • a) Going back one alert level would be assessed when: One item in each of two of the three columns are met.
  • b) Going back to red alert level would be assessed when: One or more in each of the three columns are met; OR by the presence of more than one trigger in any given column, plus the addition of one more trigger from any other column.
  • c) Going to lockdown would be assessed when: A recommendation to move to lockdown may be made by the COVID Measures Assessment Team based on cases in a zone including if two items in each of two of the three columns are met; two items in one column in addition to one item in the other two columns are met; three items met in one column and one item met in another column. In addition, any of the following could trigger a lockdown:
  • A large spike in cases unlinked to a known cluster or chain of transmission
  • Evidence of a super-spreader or variant case having exposed individuals across a zone
  • Importation of a case linked to travel and noted transmission of cases outside of their household
  • At least four (4) of the following sectors affected by a COVID-19 case or outbreak:
    • Acute care
    • Daycares
    • Long-term care
    • Parks / Outdoor recreation
    • Restaurants
    • Schools
    • Transportation
    • Workplaces

  • Doubling time of cases in less than six (6) days (not applicable if we still have low number of cases).
  • More than three (3) unlinked chains of community transmission in less than a six (6) day period.
  • Outbreaks in high vulnerability settings where there is risk of transmission to the community.
  • Indication of a super-spreader event, when 10% of attendees develop one or more symptoms (minimum 20 attendees).

Public Health
  • 10% or more of all contacts cannot be reached by Public Health within 24 hours after being identified through case interview.
  • Public Health is not able to reach or actively monitor all identified close contacts within 48 hours since last contact.
  • Insufficient facilities for non-hospitalized COVID-19 infected people who cannot be safely cared for at home (i.e. vulnerable populations, group settings which do not allow for self-isolation).
  • Compliance with public health directives and recommendations are no longer being followed by the public (e.g. physical distancing, masking, parties, poor record keeping at businesses, etc.).
  • Large number of public exposures at high-traffic venues (e.g. concerts, bars, schools)

Health Care
  • Inability to scale up to sustain a sudden increase in the number of ICU patients from current census (including staffing).
  • Health system can no longer screen and test the required number of asymptomatic patients in a timely manner.
  • Less than a four (4) week supply of PPE for double the current case load.
  • More admissions than discharges for COVID-19 over three (3) consecutive days.
  • Threat to baseline capacity in clinical health services.
  • Health-care facilities can no longer be structured to reduce possibility of exposure at triage and all other locations.
  • Increasing number of new health-care worker infections (affect workforce and indicates poor infection prevention and control practices).
  • Large number of health-care workers under self-isolation, affecting ability to deliver health services.

Risk assessments


  • There are three (3) unlinked chains of community transmission within 6 days.
  • Health-care system is overwhelmed.
  • Public health measures are no longer effective.
  • Outbreaks and new clusters can no longer be controlled through testing, tracing and self-isolation measures.


  • Travel-related cases and new chains of community transmission are accelerating.
  • Health-care system still able to manage but under pressure.
  • Compliance with public health measures decreasing.
  • Outbreaks can still be controlled through public health measures.


  • Sporadic travel-related cases and isolated outbreaks are occurring.
  • Individual cases and outbreaks can be controlled through testing, tracing and self-isolation.
