COVID-19 Update

Our protocols and procedures for Covid-19:


As you all are aware there are screening protocols we have to follow, and our main concern is the safety and well-being of your kids and our staff. If your child is showing one or more symptoms (Sore throat, Stuffy nose/runny nose, Headache, Nausea/vomiting/diarrhea, Fatigue/lethargy/muscle aches/malaise) we will be calling you to come to pick your child up and to monitor their symptoms for 24 hours before returning to the centre.


Likewise, if your kids are showing symptoms at home please have your child stay home and again monitor the symptoms before returning.


We understand this is a difficult time for everyone, but we are looking out for everyone’s safety.
