HIV Non-Disclosure and Criminal Liability in Canada

The law surrounding HIV non-disclosure is one of the most complex areas of Canadian criminal law because it involves evolving medical science and serious legal consequences.

Canadian courts have held that, in certain circumstances, failing to disclose HIV-positive status before sexual activity may lead to criminal liability. The central question is whether there was a realistic possibility of transmission.

The Supreme Court of Canada has linked criminal liability to the concepts of dishonesty and deprivation. A failure to disclose may invalidate consent where the legal requirements are met.

Medical evidence often plays a critical role. Viral load levels, treatment history, condom use, and the nature of the sexual activity may all affect the legal analysis.

Current medical science recognizes that individuals receiving effective treatment and maintaining a suppressed viral load may present little or no realistic possibility of transmission in certain circumstances.

Cases involving HIV allegations are highly fact-specific and frequently require expert evidence. Anyone facing such allegations should obtain experienced legal representation as early as possible.
