body: Can a customer of mine waive negligence caused by me when doing any business activity on assets/property? What if the property belongs to someone else, but I state that they take all responsibility as well? Provided that I am specific and the waiver is clearly written, is it enforceable? Can this replace the need for general liability insurance? 
  
  
  For an example, I pressure wash property for a living. While washing, I scratch a vehicle, however, the customer has signed a waiver that protects me from being sued/pay for damages. What if the car is leased, however, I state that they are responsible to pay X for all damages caused by my negligence? 
  
  
  All activities are based in Ontario, Canada.
