Under the terms of his probation order, Leadley was prohibited from visiting any public park, swimming area, playground or community centre where there are, or may be, children under age 14.

Police say they received complaints about a man fitting Leadley’s description being seen in the vicinity of the YMCA on Durham St. and the daycare centre.

Leadley was in bail court Thursday and waived his right to a bail hearing and was granted an adjournment until next Wednesday, Aug. 30.

Leadley will remain in police custody until his next court appearance.

A picture of Leadley was released in July when police issued the public notice saying they considered him a high risk to re-offend and that he was moving to the Sudbury area to live with members of his family.

Leadley has been convicted of numerous sex offences against children while living in southern Ontario.

In August of 2004, Leadley was convicted of attempting to lure a 13-year-old boy over the Internet. He served an 11-month sentence.

Six years ago, he was given a 12-month sentence for sexually touching two 13-year-old boys inside his apartment.

Leadley was convicted of other sexual touching charges against three children 10 years ago and received a three-year probationary period.

ST. CATHARINES – A high-risk offender who preys on children is back in custody after being charged with possession of child pornography.

Niagara police arrested William Leadley, 39, Monday. He is to appear in a St. Catharines court for a bail hearing today.

Leadley has been convicted of numerous sex and property offences, including a 2004 attempt to lure a 13-year-old Hamilton girl into having sex.

In January 2005, Leadley was jailed for 11 months after pleading guilty to using a computer to lure the girl through the Internet.

“It was a despicable act with lasting consequences” for the girl, Ontario Court Justice Bernd Zabel said at his sentencing.

Court was told the offences happened in August 2004, while Leadley was in a gay relationship with the victim’s uncle. The uncle also has been charged.

Leadley propositioned the girl while she and her family were on a visit to Niagara Falls. She rejected him.

The next day, the two men phoned her and asked her to bring friends over to see them. Leadley offered her $50 for each friend she would bring to sleep with him, the court was told.

The girl again refused and told her mother, who contacted Leadley through an Internet messaging site pretending to be her daughter.

Court was told he made the same offer to the mother, who called police.

Hamilton police launched a sting operation. Pretending to be a 13-year-old girl, Detective Doug Rees of the Hamilton child pornography unit contacted Leadley on the Internet.

Over four weeks, Leadley sent explicit pictures over the Internet. He offered to send a taxi to pick up the girl and take her back to St. Catharines for sexual activities. Police arrested him at his St. Catharines home.

When Leadley was released, Niagara police issued a public warning regarding his return to St. Catharines.

Niagara police Constable Nilan Dave said Monday Leadley was arrested at a Queenston Street address after an investigation by detectives from the child exploitation unit and the offender management unit.

He is charged with one count each of possession of child pornography and breach of recognizance.

He is currently bound by an order prohibiting him, for a period of 10 years, from attending schools, parks, playgrounds, daycares, community centres or anywhere children are present or are reasonably expected to be present.


A convicted child molester, once the subject of a Niagara Regional Police alert, has been convicted of sexual interference involving a 15-year-old girl.

William Leadley was sentenced Tuesday to two years in jail less a day for having sex with the girl who had a cognitive disability and was two months shy of her 16th birthday. He’s previously been convicted for molesting boys and trying to lure a girl for sex over the internet.

Assistant Crown attorney Holly Nickel asked the judge to recommend Leadley be sent to the Ontario Correctional Institute for specialized sex-offender treatment.

She said he should undergo any assessment, treatment or counseling suggested by a probation officer.

Leadley pleaded guilty to sexual interference in Superior Court for actions during a birthday party at his St. Catharines apartment on Dec. 10, 2010.

The court heard Leadley, then 39, started dating a 20-year-old woman in fall 2010 and told her he was only 27.

They held a get-together for the woman’s 21st birthday at Leadley’s apartment.

The woman, a 15-year-old female and a 20-year-old male arrived at the party. All three had cognitive delays and, despite the age differences, were in a special needs class in high school.

The group drank alcohol and the 15-year-old girl became very intoxicated, court heard.

They engaged in sexual behaviour, with all moving from the living room to Leadley’s bedroom. For 20 to 30 minutes they engaged in kissing and touching. Each male had sexual intercourse with each female.

One month later, the woman who had been dating Leadley discovered his true age and criminal history. She contacted police.

Leadley was on probation at the time and was not supposed to be in the presence of anyone under 16 years of age.

The two years less sentence a day was a joint submission.

“Quite frankly, I think the sentence is less than might otherwise be imposed,” said Judge Linda Walters, adding she understood the Crown had problems with witnesses.

Nickel said the case was causing extreme emotional difficulty for one witness. Another witness had a medical condition that flares up because of stress levels. A third witness was not located.

Leadley’s lawyer, John Lefurgey, said there may have been some problems of proof if the case had gone to trial.

He said Leadley also suffers from cognitive difficulties, though he didn’t have a medical assessment.

Nickel told the judge that by sending Leadley to jail for two years less a day, the judicial system can keep track of him after he gets out through a probation term.

That’s not something that could be done if he’d been given a penitentiary term.

He was given two years less a day, minus nine months of pretrial custody, and put on probation for three years.

During that time, he’s obliged to report to a probation officer and must actively participate in treatment suggested by the probation officer.

He can’t go near the witnesses or be with anyone under 16 years old.

Nickel told the judge Leadley had specific and related criminal history with respect to minors in 1996 and 2000.

In December 1996 he was convicted on three counts of sexual interference for sexually touching three young boys, two aged 7 and 8 in his apartment.

He was jailed again in 2000 for sexually touching two 13-year-old boys in his St. Catharines apartment.

In January 2005, Leadley was given an 11-month sentence for using the Internet to try to lure a 13-year-old girl into having sex in Hamilton.

Niagara Regional Police notified the public in a rare alert in July 2006 that Leadley, whom they described as a high-risk sex offender, had moved back to Niagara.

The public warning was issued through the Community Notification Advisory Committee in the interest of community safety.
