Elementary teachers hit the picket lines today in several boards, largely in eastern and northern Ontario and including Ottawa, as part of their rotating strikes.

The Ontario English Catholic Teachers’ Association released a statement saying negotiations concluded without an agreement and that its members will be moving ahead with a province-wide strike on Tuesday.

The Elementary Teachers' Federation of Ontario kicked off the week by targeting some of the province's largest school boards.

Education workers and the province reached a tentative agreement Sunday night, hours before they were set to go on strike.

Dozens of school boards intended to close Monday as the Canadian Union of Public Employees (CUPE) and the Ontario government were stuck in contract negotiations.

The Simcoe Muskoka Catholic District School Board said it's in the "best interest of student safety" to cancel classes on Monday if CUPE workers strike.

When asked about the premier's current whereabouts, a spokesperson said, "The premier is in Ontario." They did not provide further details.

Several Ontario school boards, including the three largest, have said they will have to close schools if the labour disruption goes ahead.

The Hamilton-Wentworth District School Board says its schools will remain open despite a looming strike on Monday by thousands of education workers.
