The emergency order, which was extended to June 2, requires everyone to remain at home except for exercise, health care, work that can't be done remotely and limited shopping such as groceries.
"We've been asked to coordinate locally with our locally school boards", said Marentette.
The province's top doctor has said he would like to see "well below" 1,000 daily cases before Ontario lifts the stay-at-home order.
Mr. Ford said there needs to be "consensus" from medical experts and teachers' unions before classes can resume. "We must stay the course as we continue to quickly vaccinate more Ontarians, including our children and youth".
From May 5 to 12, the number of patients with COVID-related critical illness in intensive care has also decreased from 877 to 776.
Ford also announced Thursday that youth between the ages of 12-17 will be eligible to book their first dose of the Pfizer vaccine as of May 31.
The spread of variants remain a major concern.
Vera Etches said Wednesday the province's stay-at-home order is working, but there's still a high level of COVID-19 in the city. "By continuing to strictly follow all measures, we can further reduce transmission of the virus, safeguard hospital and public health capacity, and save lives".
USA says vaccinated people can stop wearing masks
She added that the CDC will soon be looking at all of its guidance and providing more specific updates soon. But any other time, if you're vaccinated and you're outside, put aside your mask.
"Friends, I know we're all eager to get back to some sense of normal, but at a time when contagious variants pose real risk to our province, we can't rush to reopen".
Chief Medical Officer of Health David Williams stated earlier this week that daily case counts need to stay below 1,000 if restrictions are to be loosened. Of those, 461,076 are resolved (92.3 per cent) and 8,374 people have died (32 more than Tuesday).
"People are frustrated. They are exhausted". Elliott said last week the province now has no timeline for the reopening of facilities such as tennis courts and golf courses.
Since his return from isolation, Ford has repeated his calls for the federal government to do more to tighten border restrictions.
Public Safety Minister Bill Blair responded to the calls, saying Ontario's pandemic problems have largely come from community transmission which has led to outbreaks in workplaces and shared living spaces.
On Monday, Dr. Williams said he wants to see schools re-open before anything else, and "as soon as we can".
The province reported 2,759 new cases of COVID-19 on Thursday, bringing the total number of cases since January, 2020 to 502,171.
