Jessie Quannaaluk, 55, was formally charged with second degree murder Wednesday in Montreal following the death of Paul Andrew Brown, 57.
Montreal police arrested the woman Tuesday after Brown was found dead with knife wounds to the upper body in Verdun.
The victim was discovered in the lobby of a building on Manning near LaSalle in western Verdun Monday evening at 6:30 p.m.
Brown had a previous history of domestic abuse charges and was facing charges of sexual offences against minors in Montreal at the time of his death.
Manning is a quiet residential street in the western sector of the Verdun borough.
This is the fifth homicide for 2015 and major crime scene investigators are on site Tuesday morning.
