Gregory Lock, a 67-year-old repeat sex offender with a decades-long history of crimes against children, has been handed his second consecutive long-term supervision order (LTSO) after serving 12 years in prison. Justice Rick Libman delivered the sentence at Toronto’s Armoury Court, warning Lock that if he continues to reoffend, he risks being declared a dangerous offender and could face an indeterminate sentence — effectively life behind bars.
Lock’s criminal history spans more than three decades, beginning with his first conviction in 1990 for sexually assaulting two young sisters in Bradford. Since then, he has accumulated convictions for attempted rape, sexual interference, possession of child pornography, and multiple breaches of probation and supervision orders. Even while under previous LTSOs, he repeatedly violated conditions by possessing child pornography, using unauthorized devices, and contacting underage individuals.
Court documents revealed that Lock has consistently refused to take responsibility for his actions, failing to complete sex offender treatment programs and rejecting anti-libidinal medication. Forensic psychiatrist Dr. Mark Pearce warned that there are “few reasons for optimism,” stressing that long-acting medication might be the only way to reduce Lock’s risk of reoffending.
Justice Libman urged Lock to reflect on his choices and engage with treatment options this time, emphasizing that his actions have caused “incalculable harm” to his victims and that the safety of children must come first. With credit for time served, Lock will remain incarcerated for five and a half more years, followed by strict community monitoring for up to a decade.
