The defendant is the person or company being sued in court.
In Ontario's human rights laws, the term disability includes many conditions. For example, a disability can be a physical condition, a mental condition, a learning disability, a developmental disability, or a mental illness. Disability also includes being addicted to or dependent on drugs or alcohol.
You could be born with a disability. Or, you could have a disability because you were sick or injured.
Discrimination happens when an employer, landlord, service provider, or organization you are a member of harasses you, treats you differently or unfairly, or refuses to accommodate you because of personal differences that are listed in the Human Rights Code. Examples of personal differences include a person’s ethnic origin, sex, sexual orientation, age, marital status, or disability.
Examples of discrimination include when an employer refuses to accommodate your disability in a way that would not cause them undue hardship. Or a landlord refuses to rent to you because of your ethnic origin. Or a travel agent refuses to serve you because of your sexual orientation. Or a trade union refuses to let you join because of your disability.
