Canadian Mounted Police’s National Child Exploitation Coordination Centre and international police agencies, located a child
depicted in Internet child pornography known by investigators as
the “S Series”. The abuser could be heard using the child’s name,
“S”, in some of the videos of his abuse.
 After interviewing the child and her mother, police arrested
the appellant, who had been a babysitter for his nieces, S and her
twin siblings, B1 and B2.
 A search warrant executed at the appellant’s home yielded
two computers and an external hard drive containing images and
films depicting the appellant’s sexual abuse of his nieces, a child
pornography collection and postings by the appellant to an anonymous and secret website devoted to distribution and trading
between producers and consumers of extreme forms of child
 It was ascertained that during the summer of 2012, the
appellant’s three nieces were left in the appellant’s care while his
sister-in-law worked outside the home. During this time, the
appellant sexually abused his nieces, recorded the abuse and
posted some of it to a website.
 A representative sampling of the images and films found on
the appellant’s devices was introduced in evidence before the sentencing judge. This included child pornography unrelated to his

anal penetration of young children, penetration of children with
objects and fingers, a movie of the anal rape of a boy under two

and an image depicting bondage of a four-year-old girl.
 A sampling of images of B1 and B2 included images of a
child’s vaginal area, insertion of the appellant’s penis in a child’s
mouth and insertion of a candle into a child’s anus. These images
were apparently used as part of the appellant’s “advertisements”
on the website. Films of one or both of the twins showed the use
of an electric toothbrush on the infant’s vagina, digital masturbation and cunnilingus. In several of the films, the child was crying
during the abuse.
 Images and films of S included attempted penetration of
the anal and vaginal areas with an erect penis, digital penetration, masturbation of the clitoris, anal penetration with a Sharpie

and 243 films. The investigating officer testified that the volume of
pornography in the collection was “not above average”, but there
