And Health Minister Patty Hajdu weighed in with criticism of some employers who, she said, have “conditions that would curl your hair”.

The situation at the Essex County farm, which was not named by the local health unit, was discovered after a mobile testing unit went there.
That was in response to calls by Ontario Premier Doug Ford to increase testing and to send mobile units to farms where migrant workers were unable or unwilling to go to testing centres.
Just two of the 98 cases reported by the Windsor-Essex County Health Unit on Sunday were due to community spread; at the farm confronting the outbreak, roughly 90 per cent of those who tested positive are migrant workers.
Local public-health officials are at the site again today to conduct in-person assessments at the farm.
Under new guidance issued late last week, employees who have no disease symptoms, yet test positive for COVID-19, are allowed to continue working at outdoor jobs, but must meet conditions, including maintaining six-foot separation from other people.
