Positive Lite editor Bob Leahy talks to Edwin J Bernard, co-ordinator of the HIV Justice Network, about HIV non-disclosure and the criminal law, particularly as it relates to the Canadian context where non-disclosure of known HIV-positive status prior to sex that may lead to a ‘significant risk’ of HIV transmission is considered aggravated sexual assault. The interview took place in Toronto, in May 2012, prior to the Supreme Court of Canada’s decision on the issue.
