Perhaps the strongest policy argument against raising the age of consent from 14 to 16 is that it would place unprecedented limits on the sexual freedom of young persons. Hence, proponents of such a change may be challenged to provide empirical evidence demonstrating that adolescents under 16 are being sexually exploited or, alternatively, that the incidence of pregnancy or sexually transmitted diseases among that age group calls for an expansion of the existing prohibitions. It must be noted that simply raising the age of consent to 16 would criminalize sexual activity between adolescents that is now legal. Because the modern sexual assault provisions of the Criminal Code no longer depend upon proof of intercourse, such an amendment could allow a 16-year-old to be prosecuted for virtually any sexual contact with a 15-year-old boyfriend or girlfriend.
