The Parole Board of Canada has denied weekend passes for a pedophile who drowned a five-year-old Calgary girl and stuffed her body into a garbage can.

Harold Smeltzer is on parole at a halfway house in Regina after serving a 27-year sentence for murdering the young girl who was snatched off the street in 1980 while on her way to kindergarten.

He was also convicted of several other sexual assaults and admitted to attacking more young girls.

The board says Smeltzer needs close supervision and should not be allowed overnight leave, but it ruled that day parole can continue for the 57-year-old for the next six months.

Smeltzer was released on day parole in 2008, but the board turned down a request for overnight leave from his Regina halfway house two years later.

As part of his parole conditions, Smeltzer is not allowed to have contact with children and he must stay away from places where they gather — like playgrounds and schools.

He is also required to continue psychological counselling.
