Randjida Khairi , 53, had her throat slashed and was stabbed five times.
Her husband has admitted to inflicting the wounds, but has pleaded not guilty to the second-degree murder charges.
"This is not a whodunit mystery," prosecutor Robert Kenney told the jury in his opening statement earlier in the trial. "You do not have to determine who did that to Mrs. Khairi."
At issue in the trial is accused's state of mind at the time.
On Wednesday jurors were shown photographs of the victim's wounds: the slash across her throat that the Crown has described as cutting through skin, muscle, vocal cords and airways, all the way to her spine, leaving Randjida Khairi to suffocate in her own blood.
The jury also heard from one of the police officers who discovered the body saying, "She appeared to be halfway decapitated ... there was no chance of her being alive."
The Crown plans to argue that Khairi, 65, killed his wife because she had been too liberal in raising their six children.
The jury has been told they will also hear testimony that Randjida Khairi planned to leave her husband over the conflict and had reached out to strangers and women's groups for help.
