Plain-Language Summary
Second-Degree Murder: Generally speaking, second-degree murder, covered by s.231 of the Criminal CodeA federal act codifying most criminal offences in Canada, is a deliberate killing that occurs without planning and does not fall under any of the categories of first-degree. Intent to cause bodily harm knowing it would likely result in death can result in a charge of second-degree murder. The killing can take place in the heat of an argument where there was no forethought of murder. If you intentionally kill another person you could be convicted and face a sentence of life in prison. Unlike first-degree murder that has no chance of parole for 25 years, parole eligibility can range from 10 to 25 years for second-degree and is at the discretion of the court.
What is Second-Degree Murder?
Under the Criminal Code, homicide is either culpable (criminal) or non-culpable. Non-culpable homicide is not a crime. Culpable homicide includes murder (first or second degree), manslaughter, and infanticide.
Murder is a single charge, classified at sentencing as either first or second degree. Both carry a mandatory life sentence. The key difference is when you can first apply for parole.
Murder is first-degree in several circumstances. It is first-degree when it is planned and deliberate. It is also first-degree regardless of planning when the victim is an on-duty peace officerPeople involved in upholding justice or correctional officer (s.231(4)), or when the death occurs during the commission of one of certain listed offences, including hijacking, sexual assault, kidnapping, or hostage-taking (s.231(5)). Other specific circumstances, such as a killing connected to criminal harassment, terrorist activity, or a criminal organization, can also result in a first-degree finding.
Everything that is murder but is not first-degree is second-degree murder (s.231(7)).
To be convicted of murder, the Crown must prove beyond a reasonable doubt that you caused the death, and that you either meant to cause death, or meant to cause bodily harm that you knew was likely to cause death (s.229). If you acted in lawful self-defenceA defence involving force used to protect against force or threat. or defence of another, you would be acquitted, not simply reclassified.
What is Needed to Convict
The Crown prosecutorA lawyer who conducts a criminal prosecution on behalf of the public. must prove beyond a reasonable doubtThe high standard the Crown must meet to prove guilt. that you are the person who committed the unlawful act and that act contributed to the death. It must be proven that you foresaw death as a probable consequence of your actions. Witnesses may play an important role at trial, describing the incident and testifying about your involvement.
You may be able to defend against the charge under s.34 of the Criminal Code. Under s.34, you are not guilty of an offence if: (a) you believed on reasonable grounds that force was being used or threatened against you or another person; (b) your act was done to defend yourself or that other person from that force or threat; and (c) your act was reasonable in the circumstances. A court will consider factors such as the nature of the threat, whether a weapon was involved, the size and physical capabilities of the people involved, and whether your response was proportionate to what you faced.
You may also be able to argue that your rights under the Canadian Charter of Rights and Freedoms were violated. One example is if police conducted a search without lawful authority. If a court finds that evidence was obtained in a way that violated your Charter rights, it may exclude that evidence under s.24(2) of the Charter if admitting it would bring the administration of justice into disrepute.
Treated as an Indictable Offence
If you have been charged with any homicide, including second-degree murder, the Crown will proceed with the charge as an indictable offenceA more serious type of Canadian criminal offence. and you will be imprisoned if convicted.
Penalty for Second-Degree Murder
If you are convicted of second-degree murder, you will receive a mandatory life sentence. A judge will set when you can first apply for paroleConditional release from custody before the full sentence ends., at a minimum of ten years and a maximum of twenty-five years (ss.745(c) and 745.4 of the Criminal Code).
If you have previously been convicted of murder (that is, of culpable homicide that is murder), you must serve a full twenty-five years before you can apply for parole. This is a fixed mandatory minimum, not the upper end of a range (s.745(b)).
If you were between twelve and seventeen years old at the time of the offence, the Youth Criminal Justice Act applies. For second-degree murder, the maximum sentence under the YCJA is seven years, made up of a period in custody of no more than four years followed by a period of conditional supervision in the community (s.42(2)(q)(ii) of the YCJA).
Upon conviction, a mandatory firearms prohibition will also be imposed under s.109 of the Criminal Code. For a first conviction, this prohibition lasts at least ten years after release for non-prohibited firearms, and for life for prohibited or restricted firearms.
When you become eligible for parole, the Parole Board of Canada will consider your behaviour in prison, your remorse, and your chances of rehabilitation. Parole does not reduce your sentence. It allows you to serve part of it in the community under strict conditions. If released on parole, those conditions apply for the rest of your life, and you can be returned to prison for violating them.
The Sentence for Second-Degree Murder
Second-degree murder is any murder that is not first-degree murder. A conviction carries an automatic life sentence. What varies is how long the person must wait before they can apply for parole.
Possible Penalties
These are maximum sentences. Actual sentences depend on the facts, criminal history, and any mitigating or aggravating circumstances.
Second-degree murder — s. 235(1)

Possible Defences and Legal Issues
This page covers more than one section. Possible defences and legal issues are set out by section below.
Second-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. Second-degree murder is any murder that is not first-degree murder under section 231(7); the Crown does not have to prove planning and deliberation or one of the specific circumstances listed in section 231 that make a murder first-degree.
Possible issues may still depend on the facts, the evidence, and whether the Crown can prove each part of the offence, including the required intent. 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.
