Case and Contact Management and Outbreak Guidance

The following information is current as of June 14, 2022

Please review the following guidance documents from the Ministry of Ontario:

Key highlights include:

  1. Owners/operators are responsible for individual COVID-19 case and contact management following the most current provincial guidance. This includes identifying COVID-19 cases and disease spread amongst Seasonal International Agriculture Workers (IAWs).
  2. Owners/Operators must report to the Health Unit when there is an outbreak as defined by:
    1. One confirmed case (i.e., by PCR or rapid molecular or antigen test) among a resident of an employer-provided housing, OR
    2. Two confirmed cases (i.e., by PCR or rapid molecular or antigen test) in workers or any other person working on or visiting an agri-food setting with an epidemiological link, within a 14-day period, where at least one case could have reasonably acquired their infection in the Agri-food setting.
  3. With the employee’s consent, owners/operators should notify the Health Unit if an employee who lives in employer providing housing test positive on a Rapid Antigen Test (RAT) and did not receive a PCR confirmatory test. 
  4. Up-to-date COVID-19 Isolation plans should continue to be made available to the WECHU upon request. Please note that isolation accommodations no longer require inspection from the Health Unit prior to occupancy. 
  5. Third-party regulated health professionals (a physician or nurse) who are providing care to a person must report to the WECHU (per the Health Protection and Promotion Act (HPPA)) if they are of the opinion that the person has or may have COVID-19 This includes facilitating voluntary health assessments as described below:

Confirmed Cases and Symptomatic Close Contacts (Probable case)

Asymptomatic (case)

Symptomatic wellᴵ (case or close contact)

Symptomatic unwell² (case or close contact)

At a minimum, one daily virtual assessment to identify symptoms

One virtual assessment for the duration of the isolation period.
For worsening symptoms, at a minimum, one daily in-person assessment for the duration of the isolation period with an escalation process for referral to a healthcare provider and or clinic

Twice daily in-person assessments per day, for the duration of the isolation period, with an escalation process for referral

Asymptomatic Close Contacts


Asymptomatic AND Fully Vaccinated and Boosted

At a minimum, one daily virtual assessment for the isolation period.
•If symptoms develop, at a minimum one in-person assessment per day with an escalation process for referral

Do not require health assessments if:

  • They have previously tested positive for COVID-19 in the past 90 days;
  • They are 18 years old or older
  • Are at a minimum, self-monitoring for symptoms.

ᴵ Mild symptoms, normal vital signs, other than temperature
² Abnormal vital signs (heart rate, blood pressure, Sp02 reading, respiratory rate, lung sounds, and temperature)
Note: The WECHU has provided a sample template for documenting and reporting the third party health assessments for farm owners/operators with the employee’s consent (see Sample Tracking tool for Daily Health Assessment of IAW ).

Referrals to the Isolation and Recovery Centre (IRC)

The farm owner/operator is responsible for isolating the IAW(s) to prevent the spread of COVID-19. The farm owner/operator must exhaust all measures to find isolation space for this individual. If all options have been exhausted and a space is not available, the farm owner/operator can contact the WECHU for a referral to the Isolation & Recovery Center (IRC).

The IRC will assist IAWs who fall into one of the following groups:

  • positive case or cases
  • any symptomatic close contacts
  • any case or close contacts that is unvaccinated
  • if the farm operator is unable to secure isolation anywhere else in the community (city/county or surrounding area)

Farm operators/owners may contact the WECHU at 519-258-2146, ext. 2264 to speak with a Case Investigator about the IRC requirements. If the IAW is eligible, the WECHU Case Investigator will complete the referral to the IRC.

Requirements, including types of tests and how long a test is valid for, will vary by country, so it is important to understand the exact requirements for each destination.
