"Ontario's students need to be able to focus on their learning - not their cellphones", Education Minister Lisa Thompson said in a statement.
The Toronto District School Board used to have a cellphone ban, but reversed it after four years to let teachers dictate what works best for their classrooms.
In a statement to The Canadian Press, the Ontario Principals' Council said school boards already have policies around cellphone use and the council would not support a further ban.
"I think we're going to have to look at exactly what they (the province) announces and see how we will go about enforcing it".
At the Greater Essex County District School Board, Superintendent of Education John Howitt said his board has had procedures in place for the use of personal electronic devices since 2010.
Ontario's students need to be able to focus on their learning - not their cellphones.
"It was the closest thing we got in our consultation to unanimity", one source said.
The province says it will be up to individual schools and school boards.
The ban will not apply when teachers want to use cellphones for their lesson, for medical reasons, and students with special needs.
"I think that it's time for the government to take back the power and give it back to the teachers inside the classroom", says Kehoe.
McRae agrees with Alberta's education minister that schools and teachers should be given the opportunity to figure out a balance on their own.
Education consultation surveys from a year ago suggested that approximately 97 percent of respondents supported some form of restriction on phones in class, according to the government sources.
WECDSB spokesperson Stephen Fields tells CTV Windsor, the planned cell phone ban and continued educational use aren't necessarily in conflict.
The provincial government is set to ban cell phones from classrooms - and many students in Windsor-Essex are not impressed.
Government officials said the code of conduct for teachers would also be changed, preventing them from letting students use their phones unless it is for education purposes. The improvements were largely seen among the students who were normally the lowest achieving.
