The app is a checklist for students to confirm each day that he or she does not have any symptoms of COVID-19.

The Toronto District School Board says there were initial concerns about the lack of space at five of its schools, but more students have since switched over to online learning.

The board says the drawn-out reopening plan is designed to help children get used to the new safety protocols in place to slow the spread of COVID-19.

"Teachers, parents and superintendents were all spoken to, but our voice was shockingly left out."

In a memo posted on the TDSB website Thursday, the board said it needs more time due to the large number of families -- more than 66,000 students -- that selected the online option.

The majority of secondary students will now begin the year on Sept. 17, which is two days later than previously planned. 

The Toronto District School Board said there was greater interest for in-person learning by parents and guardians of secondary school students compared to those of elementary school students.

"Are we prepared? I think we are better prepared today than we were in late March, absolutely, and I think as a board we will be as well."

The Toronto District School Board says parents can shift students on Oct. 13, Nov. 23 and Feb. 16, 2021.

The Toronto District School Board is searching for additional spaces to hold classes this fall, but says it won't know how many are needed -- or where they'll be located -- until parents of elementary students confirm whether they'll be sending their kids to school in person.
