The first step is to familiarize yourself with Bill 10, go to www.cicpo.ca, all of the information is there. It will have a serious effect on the way you run your business. If after that you feel it is something you still want to do, then make a contract that includes all of the policies you want your parents to follow ie: sick days for you and the children, vacation for you and the children, payment and late fees, illness policies. There are many more and if you search contracts in the search bar for this forum you will find lots of info. I hope this helps.
