Just for anyone who is uncertain -

From the Ministry of Child and Youth Services website:

"In the Province of Ontario, you may care for up to five children under the age of 10 years, in addition to your own children, at any one time. Any premises that exceeds this number must be licensed as a day nursery and meet all of the requirements as outlined in the Day Nurseries Act (R.S.O. 1990, c.D.2, O.Reg 262)
As an informal caregiver, there is no restriction as to the ages of children that you may care for, under the age of 10 years of age (i.e. you may care for any combination of infants, toddlers, preschoolers and school-aged children) as long as you don't exceed five children, in addition to your own, at any one time.

If you are a provider with a licensed Private Home Day Care agency there are some restrictions that must be adhered to, as outlined in the Day Nurseries Act. If you have children of your own that are under the age of six years, those children must be counted as part of the five children in care. If the agency places a child in your home that is over the age of 10 years, this child must also be counted as part of the five children in care. Of those five, the following restrictions apply:
* two handicapped children
* two children who are under two years of age
* three children who are under three years of age
* one handicapped child and one child who is under two years of age
* one handicapped child and two children who are over two years of age but under three years of age"

I'd encourage your friend to report her first, but let her know that if she doesn't, you feel compelled to do so yourself. I agree with the previous posters - if anything were ever to happen, this would come down on ALL of us. Sad, but true.
