There are quite a few child care agencies in the market. (Search Google using 'Nanny Toronto', tons of them.) The way they work is (at least @ Wee Watch): they will provide several child care providers in your desired area, you will have interview with them.( Of course they are going to impress you to get the chance.) You might find out a lot of information on the web about how to determine whether it is a qualified provider or not. They are all screened by Wee Watch for health and security aspects. Personally I think it is better than hiring someone's parents to take care of your kid.
