Two convicted killers will serve consecutive life sentences for the first degree murder of Laura Babcock, Canadian media has reported.

Dellen Millard, 32, and Mark Smich, 30, are already serving life sentences with no parole for another murder.

The family of Babcock, whose body was never found, reportedly said in a statement earlier this month that they "learned to hate" after her murder.

Millard and Smich will not be eligible for parole for 45 years.

Babcock, a 22-year-old university graduate, was killed in July 2012.

Ontario Superior Court Justice Michael Code called the consecutive sentences "proportionate and just" in this case.

A Toronto jury convicted the men in her killing last December.

In a victim impact statement earlier this month, Babcock's family said the men had "made us hate", according to the Canadian Press.

"We always taught our children not to use the word hate. It is too horrible and destructive, but you men have made us hate," they said. "We've learned to hate."

Prosecutors said during the trial that Millard wanted to get out of a love triangle with the young woman.

They argued that Millard and Smich shot and killed Babcock and used an animal incinerator to get rid of her remains.

An animal incinerator was also used by the two men to burn the body of Toronto-area man Tim Bosma.

The duo killed the 32-year-old father after answering an advertisement Bosma posted in an attempt to sell his truck.

Millard faces another first-degree murder charge for allegedly killing his father in November 2012. He is to stand trial again in April.
