A B.C. Supreme Court judge in New Westminster imposed the sentence on 36-year-old Zhongming "James'' Mou on Friday.
Mou was initially charged with first-degree murder in the death of 27-year-old Yating "Lancy'' Hu, but pleaded guilty to second degree murder earlier this month.
Hu vanished in July of 2011 and Mou gave police conflicting stories about her disappearance.
Her body was found a month later in the Fraser River off Richmond.
The couple's two young children are now being cared by by Hu's grandparents. (News1130)
