A housing provider cannot refuse to rent you a self-contained unit just because you have a guide dog. If this happens to you, your legal rights under the Blind Persons’ Rights Act may have been violated.
In response, you may want to file a complaint with the police who have the authority to investigate and lay charges in this type of situation. Some police officers may not be aware of their authority to enforce the Blind Person’s Rights Act, so you may need to inform them.
