An eight-year prison term - less time served - has been handed out to a Saskatchewan man for sexually assaulting and impregnating his granddaughter.

In 2015, the man, whose identity cannot be revealed due to a publication ban on the girl's identity and his relationship to her, was arrested and kept in custody as the case made its way through court.

Court heard that the assaults began when the girl was 10 and continued for three years until she gave birth to his child at Wynyard hospital in 2014.

The girl stated in court that her grandfather told her to lie and say another man forced her to have sex. 

A month later, she filed a report to the Wadena RCMP, with a DNA test eventually confirming that he was the father of the child.

The man pleaded guilty to two counts of sexual assault, with the eight-year sentence being given.

Due to time already served, he will remain in prison for just over six more years and will have numerous conditions upon his release, including not being allowed to be around kids or in places where kids are likely to be.
