The Assisted Human Reproduction Act (AHR Act) is a piece of federal legislation passed by the Parliament of Canada. The Act came into force on 29 March 2004. Many sections of the Act were struck down following a 2010 Supreme Court of Canada ruling on its constitutionality. The AHR Act sets a legislative and regulatory framework for the use of reproductive technologies such as in vitro fertilization and related services including surrogacy and gamete donation. The Act also regulates research in Canada involving in vitro embryos. The AHR Act was the first law in Canada to regulate the use of reproductive technologies and related research. Most other Canadian policies on AHR rely on the Act and its provisions. By 2015, Canada was one of only a few countries worldwide to comprehensively address assisted human reproduction through policy.
