The fire department arrived Monday around 9 p.m. ET at Mary Shadd Public School near Finch Avenue East and Nielsen Road after someone discovered that the kindergarten play area was on fire, according to a letter principal Annessa Ali sent home with students Tuesday.
The community spent five years fundraising the money to build the playground in a special section of the schoolyard for kindergarten students, said Ali. The $20,000 play area was installed last summer.
The school's insurance company does not cover a replacement, read the letter.
The school is hosting a fundraiser at 2:30 p.m. Wednesday.
"We ask Torontonians to open their hearts to help," wrote Shari Schwartz-Maltz, a board spokeswoman.
Toronto District School Board employees have removed the charred remains from the play area, and the grounds are safe for students.
The Toronto police are investigating the incident.
