MURDER, MANSLAUGHTER, AND ATTEMPTED MURDER

---

First-degree murder refers to a murder that is both planned and deliberate. A murder is planned if it was conceived and thought of before it was carried out. A murder is deliberate if the acts involved were intended and purposeful. 

Any culpable homicide that is not murder is manslaughter. Since “murder” is defined as the intentional killing of a human being, any murder committed without intent to kill is manslaughter. 

Manslaughter by criminal negligence requires that the person’s act or omission qualified as a “marked departure” from the standard of behaviour expected of a reasonable person in the circumstances. The offence also requires that death or bodily harm was a foreseeable consequence of the defendant’s act or omission.
