Babysitter Needed for my Children

We are looking for a great nanny for 2 children in Ontario. We would prefer someone who could help out with homework once school starts but during summer just play with the children and prepare them lunch I am normally able to prepare breakfast. Once my daughter is back in school the position would require pick up from school and during the day the sitter would only watch my son. We would prefer a nanny who has their own car, who does not smoke and who is CPR certified.
