Bare Oaks refuses to delete the nude photos of me.

Bare Oaks in Ontario Canada has pictures of me naked as a child. When I asked Bare Oaks management to delete the photos, they refused by saying the pictures aren't illegal. I understand it isn't illegal, but shouldn't they delete them if I ask?

My father is a pedophile. That's why he went to nudist camps and why he's kept decades of newsletters full of naked children. He gave consent for me to be photographed, but I withdraw that consent.

Am I being unreasonable?
