Wolfe, 58, pleaded guilty in March to 20 charges, including making child pornography and sexual assault.
He admitted to recording videos of him sexually assaulting young girls over the span of a decade and taking pictures.
A dangerous offender medical assessment was ordered in June.
The Crown feels Wolfe meets the requirements of a dangerous offender and are now seeking the designation, which could result in an indeterminate sentence.
Wolfe was originally arrested in 2014 during a Canada-wide operation that targeted sex offenders.
He originally faced more than 30 charges, but that number was reduced when he pleaded guilty
A hearing date has not been set.
