Jobs in Barrie, ON

I'm a single parent that works rotating shifts for Honda, and recently received full custody of my son, an 8 year old boy named James. He is low maintenance and pretty good at entertaining himself, but due to the hours I work he will need care at unusual hours as well as someone to take him to and from school (walking distance). I rotate schedules every 2 weeks, and the care needs will change quite drastically between the shifts. When I am on days it would be early mornings and roughly 5 hours of total care. When I am on nights it would be roughly 11.5 hours and until quite late (2-3am). I would also need 1 Saturday per month. This would average to just over 8 hours a day over the course of the month.
