Ontario is changing its COVID-19 symptom screening guidance for the province's schools and child care centres.
The province is now asking parents to keep their children home from school for 24 hours if they have either a runny nose or headache.
If a child has both of those symptoms they are asked to consult a health-care provider or have a COVID-19 test before returning to school or child care.
Previously, the government had asked that children with either single symptom stay home until they received a negative COVID-19 test or other medical diagnosis.
Ontario is also removing abdominal pain or conjunctivitis from its screening list.
Earlier this month, British Columbia removed 10 symptoms from their school screening sheet including runny nose.
