Babysitter wanted for childcare in Toronto

Hi, I'm a single father and I am looking for a caring female nanny/babysitter to watch my son while i go to work. My son is very energetic and has a diagnosis of Autism and so it would be great to get someone with that experience. My son doesn't need much when i'm away at work and my focus is on feeding him and helping him to go to bed. My job can run from 3 days per week to 6 days per week and it's usually evening hours with occasional overnight hours.
