I too am in Ontario. Max of 5 children like playfelt stated.

Children:
F/T child - age 23 months
P/T child - age 15 months
Before and After School - 2 children, ages 5 & 7 (bus comes at 8:25 and 4:10) so it doesn't interfer with nap times. I have these children 3 days a week, every second week until the end of June.

Will have a F/T child starting Sept/Oct, will be age 1 yr!

I will never have 5 children in my care to be full. Luckily, we don't need the extra income. They are a good group of kids. I've had the 23 month old for almost a year - she's like a niece to me.
