A judge reserved his decision at the sentencing hearing for Kevin Maryk today.
Maryk pleaded guilty earlier to one of the province's most notorious missing-persons cases.
Dominic Maryk, 13, and Abby Maryk, 11, vanished while on a court-authorized visitation with their father in August 2008.
They weren't located until May 2012 in Guadalajara, Mexico.
The children were kept in what the Crown has called "deplorable" conditions, which included having no access to schools, medical care or even friends.
After hearing more arguments today, provincial court Judge Ted Lismer put Maryk's sentencing over to Sept. 11.
Maryk was asking for 25 months of time served in custody and an immediate return to the community. The Crown was seeking a five-year prison sentence, which is half the 10-year maximum for abduction.
