Nanny Job in Oakville, Ontario

We are a family of four with both parents working full-time and both kids in school full-time. I am looking for a part-time mother's helper to prepare meals and to do some housekeeping. Specifically, I would like help 2-3 times per week for 3 hours per day (between 3-6 pm). The wage will range between $12-$15/hour. My son is allergic to milk, eggs and nuts. So far, there reactions have all been taken care of with Benadryl. But he has an epi-pen with him at all times in case of an emergency.
