Nanny Needed For 3 Children In Ontario.

We are looking for a great nanny for 3 children in Ontario. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who has their own car and who does not smoke. During the summer it would be 2-3 days a week. I work at a hospital so the days vary. Once school starts in August it would be all day with the infant and then walk to pick up the older two at school.
