JP Morgan and Asha Bhaneji signed a contract that JP Morgan will perform renovation services for 123 Hurontario Rd., Mississauga, ON.Asha Bhaneji walks into your office upset and wants to sue the contractor in this case because she alleges that the contractor agreed to remove all of the old existing washroom materials but now says that that wasn't "part of the deal" and wants an additional $500 to rent a truck to remove the old washroom materials.Based on your knowledge, what legal advice would you give Ms. Bhaneji?
