The dominant purpose and effect of the legislative scheme is to prohibit practices that would undercut moral values, produce public health evils, and threaten the security of donors, donees, and persons conceived by assisted reproduction.

The impugned provisions affect rules with respect to the management of hospitals, since Parliament has provided that the Act applies to all premises in which controlled activities are undertaken.

[citation needed] The matter of the impugned provisions is regulation of virtually every aspect of research and clinical practice in relation to assisted human reproduction.

8, 9 and 12 in purpose and effect prohibit negative practices associated with assisted reproduction and fall within the traditional ambit of the federal criminal law power.

Sections 45 to 53, to the extent that they deal with inspection and enforcement in relation to constitutionally valid provisions of the Act, are also properly enacted under the criminal law power.
