This chapter examines the ability in Canada, the United States, and minimally Mexico. It reviews disability discrimination legislation, including the Constitution, as well as other important legislation. The Canadian Human Rights Act was implemented and came into force on 1 March 1978. Influential thinkers, such as Jefferson, Madison and Jay, believed in a national government and a Bill of Rights, which they outlined in the Federalist Papers 1787-88. The American Constitution is the paramount tool for redressing wrongs, the judicial system in the United States has seen the use of two acts, the Equal Pay Act and the Civil Rights Act as alternatives to the Constitution, with the latter having been the most successful in guarding against discrimination. The Voting Accessibility for the Elderly and Handicapped Act of 1984 generally requires polling places across the United States to be physically accessible to people with disabilities for federal elections.
