If you need to know for sure, google "dayhome regulations" or some such phrase, plus the name of your province. I know that where I am, a home child care centre (licensed or non) can have 6 children under 10 NOT including their own children, at ANY time. Of those kids, only 3 can be under 3. And of those kids, only 2 can be under 2 if you are licensed. And yes, the B/A school kids count.
