Const. Steve Dery of the Kativik Regional Police Service was shot while responding to a domestic dispute in Kuujjuaq, about 1,500 kilometres north of Montreal.
Dery was originally from the Ottawa area.
Ottawa police and the Kativik Regional Police Force say the funeral will be held at the Notre-Dame Cathedral Basilica (at 385 Sussex Dr.) starting at 11 a.m.
Ottawa police say they are still working with the Kativik police and the Dery Family on how to honour the 27-year-old officer at the funeral.
Visitations will be held on Friday at the Heritage Funeral Home in nearby Orleans.
A second officer was wounded during the shooting last Saturday but his life isn't in danger.
