Violent and Assaultive Offences (Sentencing)
A key societal right for all people is the right to be "free from unconsented invasions on his or her physical security or dignity". It is a "central purpose" of the criminal law to protect the public from such invasions.
Provocation will have an effect on sentence for assault. Where the injury occurred while in an initially consentual fight the sentence will be less than where the attack was unprovoked and against a defenceless victim.
In offences of violence involving a weapon, "the primary sentencing objectives to be applied are deterrence and protection of the public."
Random acts of violence upon strangers will often attract jail sentence. 
Sports-related violence can frequently allow for discharges.

Key Aggravating Factors
- History of spousal abuse / previously assaulted same victim
- Criminal record for violence or related convictions
- Spouse or common law spouse is victim = breach of trust
- Serious injuries to complainant
- Planned or pre-meditated
- Use of weapon
- Children witnessed the assault or were present when the assault occurred
- Offence occurred in the home
- Degradation of victim
- Separate acts occurring over a period of time
- No remorse
- Home invasion
- Intoxicated at time of offence
- degree of provocation
- circumstances that make it desirable to preserve the family relationship
- evidence that it was out of character or isolated event
Section 718.2(a)(ii) provides that “evidence that the offender, in committing the offence, abused the offender’s spouse or common law partner...shall be deemed to be an aggravating factor." This can include those who are in a sexual relationship but may not be co-habitating.
A spousal connection between the offender and victim is an aggravating factor at common law.
Denunciation and Deterrence are Primary
The primary principles are denunciation and general deterrence for domestic violence offences.
Offences of violence that are between ex-partners would not be considered a case of domestic violence.
Courts are not to tolerate domestic violence within the communities.
Custodial sentences are considered the norm where significant bodily harm has been inflicted in a domestic violence situation. This is in part due to courts recognizing that domestic violence is often part of continuous abuse ongoing in the relationship.

Position of Trust
Offences of violence against children by their parents requires a strong response due to their inability to defend themselves and the fiduciary duty towards them.
The most important factors to consider is the child's exposure to harm and the forseeability of the harm.
Certain courts have divided offences involving the assault of children into three categories:
- cases involving the application of force with the expectation of causing injury or indifference to it;
- cases involving the application of force where a parent was immature and unskilled and acting out of emotional upset, frustration or temper and did not fully appreciate the serious injuries which might result; and
- cases involving diminished responsibility through mental disorder where the abnormal mental condition of the accused requires the treatment of the offender to be given priority over the principles of general and individual deterrence.
Police officers put themselves in harm's way to protect the community and preserve a just, peaceful and safe society. "Violent attacks upon police officers who are doing their duty are attacks on the rule of law and on the safety and well-being of the community as a whole. Sentences imposed for those attacks must reflect the vulnerability of the police officers, society's dependence on the police, and society’s determination to avoid a policing mentality which invites easy resort to violence in the execution of the policing function."
- R v MacArthur,  O.J. No. 721 (ONCA) at para 49
