What rights does a parent have over an 18-year- old child living at home in OntarioCanada?

In Ontario, when a child reaches the age of 18, they are considered an adult and have the right to make their own decisions. Parents no longer have the legal authority to compel their 18-year-old child to follow house rules or restrict their activities without their consent. However, parents may still have a moral or ethical influence over their child's behavior and choices.
