Very sad my heart goes out to the family.  Sadly, the inability of the education to keep this and other children safe is one of the outcomes of failed educational policy.

Other news outlets are reporting that this 5 year old student was special needs, it was his first day of kindergarten at the first recess when he drowned.  The trend in education is to integrate all students, but if they don't have proper supports, which are expensive, this approach doesn't work and is dangerous.  You can't integrate 6 autistic students into 6 separate classes with the same 2 EAs that you had before the integration when those 6 students had a separate recess time.  Each one of the integrated students needs an EA, governments in most, if not all, provinces have pushed integration while cutting EAs at the expense of the most vulnerable.
