Mental Health Defences in Criminal Cases: A Calgary Lawyer’s Perspective

Legal Framework for Mental Health Defences in Canada
Section 16 of the Criminal Code: Not Criminally Responsible (NCR)
The primary statutory basis for mental health defences in Canada is Section 16 of the Criminal Code, which establishes the legal standard for a verdict of Not Criminally Responsible (NCR) on account of mental disorder. This provision states that a person is not criminally responsible if, at the time of the offence, they were suffering from a mental disorder that rendered them incapable of appreciating the nature and quality of the act or knowing that it was wrong.
In Calgary, NCR cases are typically supported by psychiatric assessments and expert evidence, and they must meet a high threshold. If successful, an NCR finding does not result in a traditional conviction but leads instead to a disposition hearing before the Alberta Review Board, which oversees ongoing care and public safety considerations.
Fitness to Stand Trial
Another critical element in Calgary criminal proceedings is the concept of fitness to stand trial. This determination assesses whether the accused is mentally capable of understanding the nature of the legal proceedings and instructing legal counsel. Under Canadian law, individuals must be fit to stand trial for the court process to proceed fairly.
If a question arises regarding an accused’s mental fitness, the court may order a psychiatric evaluation. In Calgary, these assessments are commonly conducted through Alberta Health Services in partnership with the Southern Alberta Forensic Psychiatry Centre (SAFPC). If the individual is found unfit, court proceedings may be temporarily halted while the person receives treatment aimed at restoring fitness.
Application in Calgary Courts
In Calgary, mental health defences are argued in both the Provincial Court of Alberta and the Court of King’s Bench, depending on the severity and nature of the charge. Local defence lawyers work closely with psychiatrists and other forensic professionals to gather the necessary evidence and navigate procedural requirements.
Because Alberta follows a case-by-case approach to mental health law, familiarity with Calgary-specific court protocols, local judicial attitudes, and access to community resources can significantly influence case outcomes.
Role of the Alberta Review Board
When an accused is found NCR, the matter is transferred to the Alberta Review Board, an independent tribunal tasked with balancing the individual’s treatment needs against public safety. The Review Board has authority to issue one of three outcomes:
- An absolute discharge (in rare cases),
- A conditional discharge with specified treatment and supervision,
- Or detention in a psychiatric facility with periodic reviews.
Types of Mental Health Defences in Calgary
Not Criminally Responsible (NCR)
A defence of Not Criminally Responsible (NCR) is available under Section 16 of the Criminal Code of Canada. It applies when an accused is found to have been suffering from a mental disorder at the time of the offence that rendered them incapable of appreciating the nature and quality of the act or of knowing it was wrong.
How NCR is Established in Calgary
Establishing NCR requires a comprehensive psychiatric evaluation, typically conducted by forensic mental health experts affiliated with facilities such as the Southern Alberta Forensic Psychiatry Centre (SAFPC). Defence lawyers in Calgary often retain independent psychiatrists to support their client’s case or to challenge Crown expert findings.
The court must be satisfied, on a balance of probabilities, that the criteria for NCR are met. This is often determined during a trial or through a joint submission if both the defence and the Crown agree on the medical evidence.
Impact of an NCR Verdict
An NCR verdict does not mean the accused is free to go. Instead of facing a traditional sentence, the individual is referred to the Alberta Review Board, which conducts hearings to determine the appropriate level of supervision. The goal is rehabilitation with public safety in mind—typically involving secure psychiatric treatment rather than incarceration in a correctional facility.
Unfit to Stand Trial
Another key mental health defence is the argument that the accused is unfit to stand trial. This means the individual is mentally incapable of understanding the nature of the proceedings or of instructing counsel.
Evaluation and Legal Consequences
A fitness assessment can be requested by either party or ordered by the court. These evaluations are usually carried out at the SAFPC. If an accused is found unfit, the court may postpone proceedings and order treatment aimed at restoring their fitness, often through medication and therapy.
Review Board Hearings and Restoration
The Alberta Review Board holds regular reviews to assess whether the accused has regained fitness to proceed. Once declared fit, the criminal trial resumes. If the individual remains unfit, the Board may order continued treatment, subject to ongoing review every 12 months.
Diminished Capacity or Mitigation
Although diminished capacity is not a formal legal defence in Canada, it can be a powerful tool during sentencing hearings. In Calgary, defence lawyers may present evidence of a mental disorder to argue that their client’s moral blameworthiness is reduced, even if the person is legally responsible for the crime.
Use in Sentencing Hearings
Psychiatric reports and expert testimony can be submitted to demonstrate how the accused’s mental illness affected their behaviour or decision-making. This can result in a more lenient sentence, including probation, treatment orders, or community-based alternatives. Judges in Calgary often weigh these reports heavily when considering rehabilitation as a sentencing objective under section 718 of the Criminal Code.
The Role of a Calgary Criminal Defence Lawyer in Mental Health Cases
Arranging Psychiatric Assessments and Expert Witnesses
One of the first steps in building a mental health defence is obtaining a comprehensive psychiatric assessment. Defence lawyers in Calgary work with trusted professionals, including those at the Southern Alberta Forensic Psychiatry Centre (SAFPC), to evaluate whether the accused meets the criteria for being found Not Criminally Responsible (NCR) or unfit to stand trial.
In complex cases, lawyers may also retain independent forensic psychiatrists to provide a second opinion or serve as expert witnesses in court. These experts can deliver compelling testimony on the accused’s mental state at the time of the offence or during court proceedings.
Navigating Complex NCR Applications and Court Procedures
Mental health defences involve highly technical legal procedures, including specific evidentiary standards and timelines. A Calgary defence lawyer will:
- File the appropriate NCR application or motion for fitness evaluation,
- Review and interpret psychiatric reports,
- Cross-examine Crown experts when necessary,
- And ensure that the client’s mental health history is accurately presented in court.
Lawyers also guide clients through Review Board processes, ensuring they are treated fairly and their progress is accurately represented in annual hearings.
Advocating for Treatment Rather than Punishment
A compassionate defence lawyer understands that mental illness should be treated—not punished. In many cases, legal counsel in Calgary will advocate for diversion programs, mental health court, or treatment-focused sentences in lieu of incarceration.
This often involves developing a treatment and supervision plan in collaboration with medical providers and presenting it to the judge or the Alberta Review Board as a viable alternative that serves both public safety and the client’s rehabilitation.
Liaising with Calgary’s Forensic Psychiatric Services and Alberta Health Services
Calgary lawyers frequently coordinate with professionals from Alberta Health Services (AHS) and Calgary’s forensic psychiatric facilities to ensure clients receive timely care. This includes:
- Ensuring medication is administered during pre-trial detention,
- Helping arrange in-patient or out-patient treatment,
- And advocating for conditions that support recovery, such as no-contact orders with treatment providers or family members.
Close communication with these institutions helps ensure continuity of care and compliance with court-ordered treatment plans.
Helping Clients and Families Understand Legal Rights and Long-Term Implications
Mental health cases can be emotionally overwhelming—not just for the accused but also for their families. A defence lawyer in Calgary provides ongoing support and education, helping clients and their loved ones understand:
- The legal consequences of an NCR or unfit finding,
- The role of the Alberta Review Board,
- Conditions of release or detention,
- And long-term considerations like travel restrictions or implications for future employment.
By providing clear legal guidance and emotional support, lawyers help ensure clients are treated with dignity throughout the legal process.
Support Services and Mental Health Resources in Calgary
Accessing Mental Health Support While Facing Criminal Charges
Calgary Mental Health Court (CMHC) and Diversion Programs
The Calgary Mental Health Court (CMHC) is a specialized initiative under Alberta Justice that provides an alternative to the traditional court process for individuals with diagnosed mental illnesses who are charged with non-violent offences. The CMHC focuses on rehabilitation rather than punishment, connecting individuals to treatment and support services instead of incarceration.
Eligible participants may be diverted from the regular court system and provided with a structured treatment plan overseen by a multidisciplinary team. Defence lawyers play a key role in referring clients to the CMHC and advocating for their acceptance into the program.
Other diversion initiatives are available through Crown prosecutor discretion, particularly for first-time or low-risk offenders, and may involve participation in community counselling, psychiatric care, or addiction recovery programs.
Community-Based Services in Calgary
Calgary is home to several reputable mental health organizations that provide free or low-cost services, including:
- Calgary Counselling Centre
Offers individual therapy, group counselling, and support for mental health, addiction, and family issues. - Distress Centre Calgary
Provides 24/7 crisis support and connects individuals in acute distress to emergency or ongoing mental health resources. - Canadian Mental Health Association – Calgary Region (CMHA Calgary)
Delivers recovery-oriented services such as housing support, peer programs, and case management for individuals living with mental illness.
These services are vital not only for the well-being of the accused but also for building compelling legal arguments around rehabilitation during sentencing or Review Board hearings.
Alternatives to Incarceration: Treatment Plans and Conditional Discharges
When mental illness plays a role in a criminal offence, Calgary courts often consider alternatives to jail that prioritize recovery and community reintegration. These options include:
- Treatment Orders: A judge may order an individual to undergo psychiatric treatment or counselling as a condition of probation or conditional sentence.
- Conditional Discharges: These allow an individual to avoid a criminal record, provided they comply with court-imposed conditions—such as continuing therapy or avoiding substance use.
- Probation with Mental Health Conditions: Probation terms may include mandatory attendance at counselling sessions, medication compliance, or enrolment in rehabilitation programs.
Protecting Your Rights Through a Mental Health Lens
Why Early Intervention by a Calgary Defence Lawyer Is Crucial
When mental health is a factor in a criminal case, early legal intervention is essential. A knowledgeable Calgary criminal defence lawyer can act quickly to:
- Arrange psychiatric assessments,
- Identify diversion or treatment options,
- Preserve crucial evidence of mental health history,
- And advocate for alternatives to incarceration.
The earlier a lawyer becomes involved, the greater the opportunity to shape the legal process around the client’s therapeutic needs rather than punitive measures.
Importance of Destigmatizing Mental Health in Legal Proceedings
Despite growing awareness, stigma around mental illness still affects how individuals are perceived in the justice system. By introducing expert testimony, advocating for treatment-based outcomes, and educating the court about a client’s diagnosis, defence lawyers in Calgary help ensure that mental health conditions are addressed with sensitivity, not suspicion.
This approach not only helps the accused—it also reinforces public confidence in a justice system that values rehabilitation and human dignity.
