Key Takeaways

• It is the law: Every business covered by the Workplace Safety and Insurance Act (WSIA) must have at least one certified first aider on site during all working shifts.

• Team size dictates the course: Workplaces with 1 to 5 employees per shift require Basic First Aid, while 6 or more require Intermediate First Aid.

• Recent WSIB updates: As of June 2026, WSIB updated its program names (formerly Emergency and Standard First Aid) to align with national standards.

• Coverage must be constant: You must account for shift workers, sick days, and vacation time to ensure a trained individual is always present.

• Hands-on learning is best: Real-life, engaging training builds the muscle memory needed to act fast during an emergency.

​

Understanding Who Needs First Aid Training in Ontario

When assessing who needs first aid training in Ontario, the first place to look is WSIB Regulation 1101. This regulation mandates that any business covered by the WSIA must provide first aid equipment, a dedicated first aid station, and trained personnel on site.

But how many people actually need to take a course? The minimum legal requirement is that at least one trained employee must be present on shift at all times. However, relying on just one person is incredibly risky. If that individual is on vacation, out sick, or even just out on a lunch break, your workplace is technically out of compliance. We always recommend training multiple staff members so you have reliable, overlapping backup coverage.

Basic vs. Intermediate First Aid

In June 2026, WSIB modernized its first aid program, updating course names to better match national Canadian standards. Choosing the right course comes down to your maximum shift size:

• Basic First Aid (Formerly Emergency First Aid): If you have 5 or fewer employees working on any given shift, at least one person must hold a valid Basic First Aid certificate. This is an 8-hour program that covers essential life-saving techniques, including CPR and how to effectively use an Automated External Defibrillator (AED).

• Intermediate First Aid (Formerly Standard First Aid): If you have 6 or more employees on a shift, at least one person must be certified in Intermediate First Aid. This comprehensive 16-hour course covers everything in the Basic program, plus more advanced topics like head and spine injuries, environmental emergencies, and sudden medical crises.

​

Why Hands-On Skills Matter

Checking off a compliance box is great for paperwork, but the true value of first aid and CPR training lies in real-life application. When an emergency strikes, stress levels skyrocket. Having an employee who has only read a manual or clicked through a slideshow is simply not enough.

​

Our training focuses on highly engaging, hands-on learning experiences. By physically practicing the "Check, Call, Care" steps on a mannequin or handling an actual training AED, your team builds vital muscle memory. This practical approach ensures that when a coworker or customer needs help, your trained staff can step up with absolute confidence and practical competence.

​

Complementing First Aid with Fall Prevention

While knowing who needs first aid training in Ontario is your first step toward compliance, preventing the accident from happening in the first place is always the ultimate goal. For many businesses, workplace fall prevention safety training is just as crucial as CPR.

​

Falls remain one of the leading causes of workplace injuries in the province. That is why pairing your first aid certification with robust fall protection education creates a comprehensive safety net for your staff. When your team understands how to properly identify hazards before they step onto a ladder or scaffold, you drastically reduce the chances of a medical emergency occurring in the first place.
