Rising Violence in Canadian Schools: A Growing Duty-of-Care Concern
Across Canada, teachers, educational assistants, administrators and support staff are reporting increasing levels of physical aggression, threats, intimidation and verbal abuse in schools.
These incidents affect more than workplace morale. They create serious safety, operational and legal concerns for schools and school boards.
Schools cannot reasonably be expected to prevent every conflict or emergency. They are, however, expected to take reasonable precautions when a risk is known, has been previously reported or can reasonably be anticipated.
As incidents become more frequent, repeated or severe, it becomes increasingly difficult to describe future harm as completely unexpected.
When Does a Safety Issue Become a Duty-of-Care Issue?
A school’s duty of care requires it to take reasonable steps to protect students, staff and visitors from foreseeable harm.
The key word is foreseeable.
A single incident occurring without warning may be difficult to predict. However, the situation changes when a school has already experienced:
Repeated physical assaults or threats
Escalating student behaviour
Previous requests for additional support
Delays in obtaining assistance
Inadequate supervision in high-risk areas
Staff injuries or near misses
Emergency procedures that are difficult to activate
A pattern of incidents involving the same individual, location or circumstances
Once these warning signs are present, the school or board may be expected to assess the risk and implement reasonable measures to reduce it.
Schools Have Responsibilities to Both Students and Employees
Schools have a duty to provide reasonable supervision and protection for students.
School boards are also employers and must take reasonable precautions to protect teachers, educational assistants, administrators, custodians and other employees from workplace violence.
These obligations may include:
Assessing workplace-violence risks
Establishing violence-prevention policies
Developing procedures for obtaining immediate assistance
Providing staff with appropriate safety information
Training employees on emergency procedures
Investigating reported incidents
Reassessing safety measures after an assault, threat or near miss
Documenting the actions taken in response to known risks
A policy alone may not be enough.
Schools must be able to demonstrate that their procedures are practical, understood by staff and capable of functioning during an actual emergency.
Verbal Abuse Must Also Be Taken Seriously
Not every rude or disrespectful comment constitutes workplace violence.
However, verbal conduct may become a serious safety concern when it includes:
Threats of physical harm
Repeated intimidation
Aggressive or menacing behaviour
Targeted harassment
Discriminatory abuse
Statements that cause a staff member to reasonably fear for their safety
Repeated verbal aggression can also be an early warning sign of escalating behaviour.
Schools should therefore have clear procedures for classifying, documenting and responding to both physical and verbal incidents.
Where Legal and Operational Exposure Can Increase
Schools and boards may face greater scrutiny when:
Previous warnings were ignored
Staff reported threats, assaults or escalating behaviour, but no meaningful review or intervention followed.
Employees could not obtain immediate assistance
Emergency procedures depended on reaching a telephone, leaving the room or contacting an office that could not respond quickly.
Known risks were not communicated
Staff members were assigned to supervise a potentially violent situation without receiving the information or procedures needed to protect themselves and others.
Safety procedures existed only on paper
Policies had been adopted, but employees were not trained, procedures were not tested and responsibilities were unclear.
Incidents were not consistently documented
Incomplete reporting prevented administrators from identifying recurring patterns, locations, individuals or response failures.
Nothing changed after an earlier incident
A serious event occurred, but staffing, supervision, training, communication procedures and emergency-response measures remained unchanged.
The Cost of Inaction
When known risks are not adequately addressed, schools and boards may face:
Occupational health and safety investigations
Compliance orders or regulatory penalties
Civil negligence claims
Workplace injury and psychological-injury claims
Union grievances
Human-rights complaints
Increased absenteeism and staff turnover
Higher insurance and replacement-staff costs
Loss of confidence among employees and families
Reputational damage
Increased scrutiny of administrators and trustees
The greatest legal concern is often not that an incident occurred.
It is whether the organization can demonstrate that it recognized the risk, responded appropriately and took reasonable steps to prevent the same failure from happening again.
Supporting Students Without Compromising Safety
Some violent or aggressive behaviour may involve students with disabilities, mental-health challenges or complex support needs.
Schools must continue to respect student rights and accommodation obligations. At the same time, accommodation does not require staff or other students to be exposed to unmanaged and serious safety risks.
The appropriate response is not to choose between student support and employee safety.
A defensible approach includes:
Individualized student support
Objective risk assessment
Appropriate staffing and supervision
Behavioural and crisis-response planning
Clear emergency procedures
Staff training
Timely access to assistance
Ongoing review of incidents and controls
Student support and staff protection must operate together.
A Practical Question for Every School Board
Every school and board should be able to answer the following question:
If a staff member becomes aware of a medical emergency, serious threat or violent incident, can that person discreetly and immediately request assistance—and can responders quickly determine what is happening and where help is needed?
Where the answer is uncertain, the organization may have a significant emergency-response gap.
Strengthening Emergency Response Without Creating Surveillance
Sentinel Shield is being developed as a staff-activated school safety infrastructure designed to help reduce the time between a serious incident and a coordinated response.
Authorized staff members use dedicated LTE-enabled devices to activate a Medical Emergency or Threat/Violence alert.
Once activated, the system can provide designated responders with:
The type of incident
The assigned device
The detected school zone
The time of activation
The response and acknowledgement status
Sentinel Shield is being developed without reliance on personal mobile phones or school Wi-Fi and without continuous staff monitoring.
It is intended to support a school’s broader safety program—not replace it.
Risk assessments, appropriate staffing, student-support planning, training, reporting, investigation and post-incident review remain essential.
The Standard Is Reasonable Preparedness
Schools are not expected to guarantee that violence will never occur.
They are expected to demonstrate that known and reasonably foreseeable risks have been taken seriously.
That means having:
A practical way to summon immediate assistance
Clearly assigned response responsibilities
Staff who understand the procedures
Reliable incident documentation
Meaningful follow-up after threats, assaults and near misses
Safety measures proportionate to the risks present in the school
As violence, threats and verbal aggression continue to affect Canadian schools, boards must move beyond general policies and demonstrate that their emergency procedures work in practice.
The question is no longer simply whether a school has a safety policy.
The question is whether help can be requested, directed and coordinated when it is actually needed.
