First Aid Kit Regulations in Ontario

In Ontario, ensuring the safety and well-being of employees is a top priority for workplaces across the province. One crucial aspect of this is the presence of adequately equipped first aid kits and trained staff members who can administer first aid and CPR when necessary.

However, understanding the regulations surrounding first aid kits in Ontario can sometimes be daunting, as the information available is often overly complicated or incomplete.

In this article, we aim to provide a clear and comprehensive overview of first aid kit regulations in Ontario, making it accessible to everyone.

First Aid Kits in Workplaces

Effective January 1, 2020, the WSIB will accept the CSA Z1220-17 First Aid Kits for the workplace. To meet the Regulation 1101 first aid obligations under WSIA, workplaces can supply the Regulation 1101 First aid kit requirements or CSA Z1220-17 First aid kits for the workplace.

In Ontario, most workplaces, including schools and other institutions, must have a first aid kit and a certified staff member to administer first aid and CPR.

The size of the first aid resources and the number of trained staff needed increases with the number of employees.

However, it’s important to note that industries have different requirements covered in a separate article.

First Aid Kit Requirements

The specific requirements for first aid kits in Ontario workplaces vary based on the number of employees and the nature of the work. Each kit needs to comply with CSA Z1220-17 First Aid Kits.

Here are additional requirements based on number of employees in the workplace:

  • Small Workplaces (1-5 Employees): Basic first aid kit requirements, including items such as bandages, gauze, and antiseptic wipes.
  • Medium Workplaces (6-15 Employees): Enhanced first aid kit requirements, with additional items like splints and CPR masks.
  • Large Workplaces (16+ Employees): Comprehensive first aid kits, possibly including oxygen tanks and defibrillators, depending on the workplace’s nature.

Considerations For Construction, Farm, and Lone Worker Sites

In these high-risk environments, the presence of a well-equipped first aid kit and trained personnel is not just a regulatory requirement but a critical safety measure.

The likelihood of severe injuries necessitates a higher preparedness level than standard workplaces.

Dynamic Requirements Based on Site Size and Risk Level:

  • Small Sites (Fewer than 10 Employees): Basic kits with essential items like adhesive bandages, gauze pads, and splints.
  • Large Sites (10 or More Employees): More comprehensive kits, including materials for major trauma care like tourniquets and larger gauze pads for significant bleeding.

Specialized Contents for Common Construction, Farm, and Lone Worker Site Injuries:

  • Protection Against Falls and Impacts: Items like padded splints and instant cold packs for sprains or fractures.
  • Eye Injuries: Saline solutions and eye patches, considering the risk of debris and dust.
  • Cuts and Lacerations: Advanced wound care supplies, including sterile dressings and wound closure strips.

Locations Of Kits

First aid stations should be easily accessible to all employees and visitors. They should be strategically located throughout the workplace, especially in areas with a higher risk of accidents or injuries.

Signage indicating the location of the first aid station should be clearly visible and well-lit. This helps individuals locate it quickly in times of need.

Staff First Aid Training

Having a well-stocked first aid kit is only half the equation. Training staff members who administer first aid and CPR effectively is equally important.

The level of training required may vary based on the size and nature of the workplace. Key points regarding staff training include:

Certification: Staff members responsible for first aid should be certified in first aid and CPR. There are various levels of certification, ranging from basic to advanced, depending on the workplace’s needs.

Training Frequency: First aid training should be periodically renewed to ensure staff members are updated with the latest techniques and guidelines.

Inspecting, Renewing, and Replenishing the First Aid Kit

Regular inspection and maintenance of the first aid kit should be done quarterly to ensure it remains fully stocked and ready for use.

Here are some steps to follow:

Regular Inspection: Designate a responsible individual or team to perform routine first aid kit inspections. Check for expired items and ensure that all supplies are in good condition.

Restocking: When supplies are used or outdated, promptly replace them to maintain the kit’s readiness.

Training Updates: As mentioned earlier, ensure that staff members’ first aid and CPR training is regularly renewed to stay current with best practices.


Understanding first aid kit regulations in Ontario is crucial for workplaces across the province.

Employers can ensure their employees’ and visitors’ safety and well-being by following the requirements outlined in various sources, such as the WSIB and federal regulations.

Remember, it’s not just about having a first aid kit; it’s about having trained staff who can effectively use it in emergencies. Regular inspections and maintenance of the kit ensure its readiness at all times.
