Ontario's Human Rights Code says that employers must do what they can to remove barriers that discriminate against people in a way that goes against their human rights. The legal word for this is accommodation.
This could mean doing things differently for you so that you are treated equally. For example, you might need a wheelchair ramp to get inside a building. Or you might not be able to wear the same uniform as other workers because of your religion.
But an employer will not have to do something if they can prove that it will cause them undue hardship.
