Housekeeper Job in Montreal, Quebec

I am looking for help 3 days a week, for about 8 to 9 hours a day. The job is primarily housekeeping: cleaning, laundry, ironing, organizing cupboards, tidying up toys. I have 4 children ages 11, 9, 6, and 4. The 3 eldest will be in school each day, but my son the 4 year old, will be present in the afternoons. Sometimes he will be with me, but other times he will need looking after. This job definitely requires a person comfortable and confident with children, and is really more housekeeping, some Nannying also. The house has 4 bedrooms, and 2 1/2 baths. We have a dog that sheds, and occasionally requires walking, but not normally.
