Wendy looking for a babysitter or nanny in Toronto

We're looking for an occasional babysitter to help out for a few hours after daycare. Most of the time it's to help out while one of us is travelling. Once in a while we're looking for someone to take care of both kids while we're out for date night. We usually pick up the kids around 430, 5ish. Home for dinner at around 530. Our son (4) is pretty self-sufficient and our daughter (1.5yo) will mostly eat herself but may need a bit of help. We would mostly be looking for someone to watch our son from 5-9pm when one of us is travelling, and the other parent is still home.
