Premier Doug Ford will be joined by Minister of Health Christine Elliott and Minister of Education Stephen Lecce to make an announcement at 1 p.m. Wednesday afternoon.
Yesterday, sources told CTV News Toronto Ford was not willing to reopen schools until the fall.
Ontario schools have been closed to in-person since April 12 following a devastating third wave of COVID-19, while students in Thunder Bay have been learning from home since March 1 when cases were surging in the city.
"My position has been always, like our public health measures table and our medical officers of health, that feel that schools should be the last to close and the first to open", Williams said at a news conference last week.
Ford already met with his cabinet earlier this morning to discuss whether or not to reopen schools.
There are just over three weeks left in the school year.

In a time of both misinformation and too much information, quality journalism is more crucial than ever. The Wall Street Journal was first to report the intelligence surrounding the earlier hospitalizations.
But other measures like the five-person limit on outdoor gatherings and restrictions on in-person retail and other businesses remain.
The province is aiming to start reopening the economy later this month with looser rules on businesses and outdoor activities.
The province's COVID-19 Science Advisory Table has said they believe schools can reopen safely on a regional basis for in-person learning for the last month of the school year.
When Ford closed schools in April, he said he wanted "nothing more than to be able to open the schools up again as soon as possible".
"The reason why schools were closed in the province, according to the Chief Medical Officer of Health, is because community transmission spiked to roughly 4,000 cases a day", Lecce responded.
"What we're considering is the health and safety of children and young people in Ontario, their teachers, and other school officials so we need to take the time to get this right", said Elliott.
