Plain-Language Summary
First-Degree Murder: is the most serious of all homicide offences and is covered under s.231 of the Criminal CodeA federal act codifying most criminal offences in Canada. First-degree murder comes down to premeditation. If you plan and kill someone you could be found guilty and face a sentence of life in prison with no chance of parole for 25 years. It is also possible to be convicted of murder while committing or attempting to commit an indictable offenceA criminal activity.
What is First-Degree Murder?
Intentionally causing the death of someone or intentionally inflicting bodily harm that you know is likely to cause death and you are not acting in self-defenceA defence involving force used to protect against force or threat. or the defence of another as defined by s.34 of the Criminal Code can lead to homicideIntentionally causing death charges. There are two types of homicides: culpable, where intent is proven; and non-culpable, which means deaths that occur in an act of self-defence or as a result of an accident. First degree murder is a killing that is planned and deliberate, such as a contract killing. According to the Code a homicide is considered first degree if: The murder is planned and deliberate; The murder occurs in the course of a hijacking, sexual assault or kidnapping, forcible confinement, or hostage taking; The murder is caused in the course of terrorist activity; The victim is a peace officerPeople involved in upholding justice or prison guard; The murder takes place in the course of criminally harassing another person; The murder occurs as part of the activities of a criminal organization; The murder occurs while intimidating a group of people or the general public, in order to impede the administration of justice, in the course of intimidating a justice system participant or in the course of intimidating a journalist to prevent them from disseminating information about a criminal organization. While planning and deliberation is the key, there are circumstances where it is not necessary for a conviction. For example, a man was charged with first-degree murder in 2011 after a police officer was run over and killed by a stolen snowplow. While there was no proof that there was a plan to use the plow to kill someone, the death occurred while the police officer was performing his duties, thus leading to a first-degree charge.
What is Needed to Convict
To gain a conviction for first-degree murder under s.231(2), the Crown must prove beyond a reasonable doubtThe high standard the Crown must meet to prove guilt. that you intended to kill the victim and that the killing was planned and deliberate. However, planning and deliberation do not need to be proven if the killing falls into one of the automatic first-degree categories set out in s.231(4) to s.231(6.2). One example is where the victim was a police officer or prison guard acting in the course of their duties. Another is where the death occurred during a sexual assault, kidnapping, forcible confinement, or hostage taking. The planning does not have to be elaborate and the Crown does not have to prove it took time to formulate. The planning can take place a very short time before the murder to be considered first degree. The judge or jury must also be convinced that your actions were essential to the homicide. Your lawyer may be able to establish reasons why your arrest was not lawful under the Canadian Charter of Rights and Freedoms. Also, if you were acting in self-defenceA defence involving force used to protect against force or threat. and did not mean to cause death you could be acquitted. Under s.34 of the Code, you are not guilty of an offence if you reasonably believe that force is being used against you (or is being threatened) or another person. However, whether the force you used was reasonable in the circumstances is assessed against a number of factors, including the nature of the threat, whether other options were available to you, and whether your response was proportionate to what you faced.
Treated as an Indictable Offence
If you have been charged with any homicide, including first-degree murder, the Crown will proceed as an indictable offenceA more serious type of Canadian criminal offence. and you will be imprisoned if convicted.
Penalty for First-Degree Murder
If you are convicted of first-degree murder you face a sentence of life imprisonment with no chance of paroleConditional release from custody before the full sentence ends. for 25 years. If you were between 12 and 17 years of age at the time the offence was committed, the maximum sentence under the Youth Criminal Justice Act (s.42(2)(q)) is 10 years for first-degree murder. This 10-year maximum covers both the period spent in custody and any time served under conditional supervision in the community. While the majority of offenders are eventually paroled it is not an automatic right. Your behaviour in prison will be considered as well as your remorse and chances of rehabilitation. It should also be noted that parole does not reduce the sentence imposed by the court, it only affects the way the sentence is served. It allows offenders to serve their sentence in the community under strict conditions of release. If you are released, you will be limited by the conditions of your parole for the rest of your life and you could be returned to prison for violating those conditions. Under s.109(1) of the Code you also face a mandatory weapons prohibition upon conviction.

Possible Defences and Legal Issues
This page covers more than one section. Possible defences and legal issues are set out by section below.
First-Degree Murder — ss.229, 231, 235
Section 235 does not list a special defence for murder. The Crown still has to prove murder under section 229 — that the accused caused the death and meant to cause death, or meant to cause bodily harm known to be likely to cause death while reckless whether death ensued. To prove first-degree murder specifically, the Crown must also prove the murder was planned and deliberate under section 231(2), or that it falls within one of the specific circumstances listed in section 231(4) to (6.2) that make a murder first-degree regardless of planning.
Possible issues may still depend on the facts, the evidence, and whether the Crown can prove each part of the offence, including planning and deliberation or an applicable listed circumstance. This is general legal information, not legal advice.
Some general Criminal Code rules can also matter, including self-defence and mental disorder, which are separate defences assessed on their own facts. Provocation under section 232 is a separate, narrow concept that can reduce a murder conviction to manslaughter in limited circumstances — it does not make a killing lawful, and whether it applies depends entirely on the facts.
Provocation — s. 232, murder reduced to manslaughter
The Criminal Code says culpable homicide “that otherwise would be murder may be reduced to manslaughter if the person who committed it did so in the heat of passion caused by sudden provocation”. Section 232 also limits what counts as provocation: the victim’s conduct must amount to “an indictable offence under this Act that is punishable by five or more years of imprisonment” and be sufficient “to deprive an ordinary person of the power of self-control”, acted on “on the sudden and before there was time for their passion to cool”. This is not a complete defence — where it applies, it reduces murder to manslaughter. Whether any of this applies depends on the exact charge, the facts, and the evidence.
