Sitter Job in Parry Sound, Ontario

My wife and I are both working and our child is one year old. She will attend regular daycare on most days, but some days our work schedules overlap for a few hours in the evenings after 5:30 and occasionally my wife starts work at 3 or 4 in the afternoon. Therefore, we need a sitter that can take our daughter from 3 or 4 until I finish work, which is usually around 5:30 - 6:30 p.m. We live on Isabella street, so we would prefer to find a sitter than can either come to our home, or that is within walking distance. We would prefer a sitter that does this full time and with some sort of training in child care and first aid.
