A man convicted of fatally shooting three Royal Canadian Mounted Police officers and wounding two others has been given Canada's harshest prison sentence in more than 50 years.

Judge David Smith sentenced Justin Bourque Friday to life in prison with no chance for parole for 75 years, four months after Bourque used a semi-automatic rifle to fatally shoot three officers and wound two others in Moncton, New Brunswick. The June 4 killings and ensuing manhunt brought the city of Moncton to a near-standstill until an arrest was made about 30 hours later.

Bourque, 24, pleaded guilty in August.

Bourque's sentence is the harshest in Canada since its last executions in 1962.

Bourque faced a mandatory life sentence, so the only issue was when he could apply for parole.
