There was a mass murder out west because some guy got dumped by his girlfriend. Happens here too. Perhaps not as common, but the fragile male ego is a common trait.
A significant percentage of women in Canada also get killed by their spouses (out of all of the women that are killed).
Granted, it's nowhere near as out of control as it is in other countries, but we're not blameless culturally speaking.
Also, here are the figure to back up my point:
