Convicted Eaton Centre shooter Christopher Husbands is expected to learn his fate on Monday.

Before Husbands, 25, hears his sentence for the July 2013 shooting at the mall, his lawyers will be arguing that the law allowing consecutive periods of parole ineligibility are unconstitutional.

Husbands faces a maximum of 50 years in prison without the chance of being released, something his lawyers don’t want to happen.

In December, he was convicted of two counts of second-degree murder in the deaths of Nixon Nirmalendran and Ahmed Hassan at the mall.

He was also convicted of aggravated assault and criminal negligence in the shooting that sparked panic and horrified the city.

The Crown had argued the shooting was the result of a feud between Husbands and the two men he killed, who were earlier involved in a vicious attack on him.

Jurors had recommended Husbands be ineligible for parole for between 15 and 25 years.

But Judge Eugene Ewaschuck allowed the Crown’s application for Husbands to serve consecutive sentences — instead of 10 to 25 years, he could serve 20 to 50 — though it’s up to his discretion.
