Chang Xi Wang, 37, stabbed his ex-wife Yan Lin and her former husband to death with a steak knife, in front of patrons and staff at the McDonald’s on No. 3 Road in August 2009.
He pleaded guilty last month to two counts of manslaughter and second-degree murder, which carries an automatic life-sentence.
Wang met Lin online when she was newly divorced but still living with her ex-husband, the court heard.
They married in China in 2007 and Lin sponsored him to come to Canada, but she continued to live with her ex-husband, Zhe Hu, which frustrated Wang.
Wang had a history of violence against his wife. Just two days prior to the murder, he completed a conditional sentence for an earlier assault.
Speaking through an interpreter in B.C. Supreme Court, Wang said it was all a big misunderstanding.
He said he initially believed he was being manipulated by Lin, but realizes now that she truly loved him.
