Learn about the time-limited restrictions and public health and workplace safety measures during the provincewide shutdown. The provincewide shutdown is in effect as of Saturday, December 26, 2020 at 12:01 a.m.

The following COVID-19 Response Framework will not apply at this time – PAUSED. The provincewide shutdown measures do have limits and requirements that differ from the Framework – Lockdown (grey).

COVID-19 Response Framework

Scheduled to commence upon the removal of the provincewide lockdown that is in effect from Dec. 26, 2020 to Jan. 23, 2021. The Government of Ontario has implemented a COVID-19 Response Framework titled “Keeping Ontario Safe and Open – Lockdown Measures”. The framework describes five levels of regional public health measures, ranging from “Prevent – Standard Measures” to “Lockdown”. These public health measures are implemented across regions of Ontario based on public health unit boundaries. Lambton Public Health serves all of Lambton County.

Adjusting and Tightening Public Health Measures

Act earlier by implementing measures to protect public health and prevent closures

Gradually loosen measure as trends in public health indicators improve

PREVENT

(Standard Measures)

Focus on education and awareness of public health and workplace safety measures in place.

Restrictions reflect broadest allowance of activities in Stage 3 absent a widely available vaccine treatment.

Highest risk settings remain closed.

PROTECT

(Strengthened Measures)

Enhanced targeted enforcement, fines, and enhanced education to limit further transmission.

Apply public health measures in high risk settings.

RESTRICT

(Intermediate Measures)

Implement enhanced measures, restrictions, and enforcement avoiding any closures.

CONTROL

(Stringent Measures)

Implement broader-scale measures and restrictions, across multiple sectors, to control transmission.

Restrictions are the most severe available before widescale business or organizational closure.

LOCKDOWN

(Maximum Measures)

Implement widescale measures and restrictions, including closures, to halt or interrupt transmission.

Consider declaration of emergency.

How does the Government of Ontario decide which regional public health measures to apply?

Decisions on the level of public health measures are made based on public health and hospital data for each region. The Government of Ontario has created a list of key indicators that will be used to inform these decisions. These indicators include:

  • Weekly incidence rate
  • Weekly percent positivity
  • Weekly effective reproduction number
  • Local trends related to outbreaks and community transmission
  • Hospital and ICU capacity
  • Public health system capacity

For some indicators, there are thresholds that relate to a given level of public health measures. For example, a weekly incidence rate that is between 10 and 24.9 per 100,000 would correspond with the yellow “PROTECT – Strengthened Measures” level. It is important to note that thresholds within a region may not all be met at the same time, and regional indicators will often fall into differing levels. Decisions about implementing new regional measures will be based on a risk assessment that takes into account all local indicators for the past two weeks. That some indicators fall into a given level does not necessarily mean the corresponding level of restrictions will be applied.

Indicators and Thresholds: Adjusting and Tightening Public Health Measures

PREVENT

(Standard Measures)

Epidemiology

  • Weekly incidence rate is < 10 per 100,00
  • % positivity is < 0.5
  • Rt < 1
  • Out break trends/observations
  • Level of community transmission/non-epi linked cases stable

Health System Capacity

  • Hospital and ICU capacity adequate

Public Health System Capacity

  • Case and contact follow up within 24 hours adequate

PROTECT

(Strengthened Measures)

Epidemiology

  • Weekly incidence rate is 10 to 24.9 per 100,000
  • % positivity is 0.5-1.2%
  • Rt is approximately 1
  • Repeated outbreaks in multiple sectors/settings OR increasing/# of large outbreaks
  • Level of community transmission/non-epi linked cases stable of increasing

Health System Capacity

  • Hospital and ICU capacity adequate

Public Health System Capacity

  • Case and contact follow up within 24 hours adequate

RESTRICT

(Intermediate Measures)

Epidemiology

  • Weekly incidence rate is 25 to 39.9 per 100,000
  • positivity is 1.3-2.4%
  • Rt is approximately 1 to 1.1
  • Repeated outbreaks in multiple sectors/settings, increasing/# of large outbreaks
  • Level of community transmission/non-epi linked cases stable or increasing

Health System Capacity

  • Hospital and ICU capacity adequate or occupancy increasing

Public Health System Capacity

  • Case and contact follow up within 24 hours adequate or at risk of becoming overwhelmed

CONTROL

(Stringent Measures)

Epidemiology

  • Weekly incidence rate ≥ 40 per 100,000
  • positivity ≥ 2.5%
  • Rt is ≥ 1.2
  • Repeated outbreaks in multiple sectors/settings, increasing/# of large outbreaks
  • Level of community transmission/non-epi linked cases increasing

Health System Capacity

  • Hospital and ICU capacity at risk of being overwhelmed

Public Health System Capacity

  • Public health unit capacity for case and contact management at risk or overwhelmed

LOCKDOWN

(Maximum Measures)

Epidemiology

  • Adverse trends after entering Red/Control, such as:
    • Increasing weekly case incidence and/or test positivity
    • Increasing case incidence and/or test positivity among people aged 70+
    • Increasing outbreaks among vulnerable populations such as long-term care residents and residents of other congregate settings

Health System Capacity

  • Hospital and ICU capacity at risk of being overwhelmed

Public Health System Capacity

  • Public health unit capacity for case and contact management at risk or overwhelmed

What do the key indicators mean?

Weekly incidence rate – For a given week, the number of newly confirmed cases in Lambton County per 100,000 population. When examined over time, this tells us how quickly case counts are increasing in a way that can be compared to other regions. Access the weekly incidence rate for Lambton County.

Weekly percent positivity – Of all Lambton County residents tested within a given week, the percent of individuals who tested positive. Access the weekly percent positivity for Lambton County.

Weekly effective reproduction number (Rt) – In a given week, the average number of secondary infections produced by a single case. Lambton Public Health does not publish the weekly reproduction number, as the population of Lambton County is not large enough to produce a meaningful estimate.

Local trends related to outbreaks and community transmission – This may include the number and severity of new outbreaks, and the number or incidence rate of cases that were acquired in the community (i.e. cases where the exposure is unknown). Access the outbreak reports for Lambton County under “Outbreaks” and “Case Details and Trends”.

Hospital and ICU capacity – Access the average percentage of occupied intensive care unit beds at Bluewater Health in a week, available  under “System Capacity”.

Public health system capacity – Access the percentage of new cases and contacts that are contacted by public health within 24 hours. Available under “System Capacity”.
