Jesse Meloche was sentenced Monday to life in prison with no parole eligibility before 10 years.
Meloche pleaded guilty to second-degree murder in the stabbing death of Lance Smoke, 40. He stabbed Smoke 10 times during an altercation in November 2011.
The two men knew each other and were part of a custody battle over Smoke's daughter.
"It was a fair sentence," said Meloche's lawyer, Dan Scott. "It was the lowest the judge could give Mr. Meloche. Given the facts, and background it was the appropriate sentence."
Scott said Meloche "is tormented" by his actions.
"His actions of November of 2011 will haunt him for the rest of his life," Scott said.
Assistant crown Dan Kerwin called Meloche's guilty plea "significant."
"It’s obviously an acceptance of remorse," Kerwin said.
Scott said Meloche's actions were "an absolute anomaly" and that his chances of rehabilitation are "phenomenal."
"That’s a gentleman who will come out with a masters of some sort," Scott said.
No members of Smoke's or Meloche's family spoke outside the courthouse.
