Class A vs Class B first aid attendant — which one does your workplace need?

If you've moved to Saskatchewan from another province — or if you've simply never had to dig into Part 5 of the OH&S Regulations before — the Class A/Class B terminology may be unfamiliar. Most provinces label their workplace first aid courses by content ("Standard First Aid", "Emergency First Aid", "Advanced First Aid"). Saskatchewan, by contrast, regulates by attendant qualification: a Class A attendant has completed at least 18 hours of training, and a Class B attendant has completed at least 68 hours. The actual courses that produce these attendants are mostly the familiar Canadian Red Cross (or St John Ambulance, or Heart and Stroke) offerings — they're just being named by the role they qualify you for, not by the course curriculum.

Here's the short version, before we get into the detail:

• Class A attendant = 18 hours of training (about 14–16 hours of first aid plus a 4–6 hour CPR component). For most Saskatchewan workplaces, this is your standard attendant qualification.
• Class B attendant = 68 hours of training (a 60–80 hour course covering advanced first aid plus an extended CPR component). Required at higher-risk, larger, or more distant worksites where Class A coverage isn't enough.

Both are recognized under Saskatchewan's OH&S Regulations, 2020. Both are issued by Red Cross, St John Ambulance, Heart and Stroke Foundation, the Lifesaving Society, or another provider recognized by Saskatchewan OHS.

What Class A actually covers

The Class A qualification is delivered through what most providers call a Standard First Aid with CPR/AED course — a two-day, ~16-hour program plus the CPR component. The Canadian Red Cross version is what we run at our Saskatoon training centre, and the curriculum reflects what an entry-level workplace first aider needs to handle:

• Emergency scene assessment and management — taking charge calmly, identifying immediate threats
• Activating EMS — calling 911, what dispatchers need from you, when to delegate
• Cardiopulmonary resuscitation (CPR) at Level C — adult, child, and infant
• Automated external defibrillator (AED) operation, including paediatric considerations
• Choking management for all ages, conscious and unconscious
• Severe bleeding — direct pressure, tourniquet use, wound packing
• Shock — recognition and management
• Sudden medical emergencies — heart attack, stroke, seizure, diabetic emergency, anaphylaxis
• Fractures, dislocations, sprains, and joint injuries — including splinting
• Head, neck, and spinal injuries
• Burns — thermal, chemical, electrical
• Environmental injuries — heat-related illnesses, hypothermia, frostbite (very relevant to Saskatchewan winters)
• Poisoning, bites, and stings

It's a substantial curriculum delivered in a hands-on format. By the end of the second day, you'll have practised CPR on adult, child, and infant manikins; operated an AED trainer through a full simulated cardiac arrest; bandaged classmates; splinted limbs; and worked through scenario-based assessments that pull all of it together.

The Class A certificate is valid for three years. Most workplaces in Saskatchewan that don't fall into the high-risk/large-workforce/distant categories meet their statutory requirement with Class A attendants.

What Class B adds

Class B is the advanced workplace first aid qualification. The most common path to Class B is through a course titled Advanced First Aid (Canadian Red Cross) or a similarly extended program from another recognized provider. These courses typically run 5 days or longer — 60 to 80 hours of instruction plus the CPR component — and they include everything in Class A, plus:

• Significantly more time on patient assessment and ongoing care
• Advanced airway management techniques, including oropharyngeal airway use
• Oxygen administration where appropriate
• Spinal motion restriction techniques
• Splinting and immobilization for a wider variety of injuries
• Extended care — managing a patient for longer periods before transport, which matters in remote work environments
• More detailed treatment of trauma, including significant bleeding control, traumatic chest injuries, and pelvic injuries
• Patient packaging and transportation considerations
• More extensive scenario-based training, often in mock-incident formats

The Class B attendant is being trained to function for longer in less-supported environments — places where the next level of care may be 30, 60, or more minutes away. Industrial first aid attendants in remote oil and gas, mining, and forestry operations have historically been the canonical Class B role; the qualification is also common in long-haul transportation, some agricultural operations, and dispatch-style roles where the attendant is a key first responder.

Class B certificates are also typically valid for three years, with renewal expected before expiry.

Who needs which? The OH&S Regulations decide

The choice between Class A and Class B isn't a matter of preference — it's set by your workplace's risk classification, workforce size, and travel time to medical aid, as laid out in Tables 2 and 3 of the Saskatchewan OH&S Regulations, 2020. Working through it requires:

1. Your workplace risk classification from the competent-person assessment under CSA Z1220-17 (low, moderate, or high risk).
2. The number of workers on each shift — and the Regulations are explicit that this is per shift, not total payroll.
3. The reasonable travel time from the worksite to ambulance service or other appropriate medical aid. The Regulations treat 30 minutes as the threshold between "close" and "distant" for purposes of attendant-level requirements.

The detail in the Regulations covers many cells of this matrix, but the practical pattern is:

• Low-risk, small-to-medium workforce, close to medical aid: Class A is the standard requirement. Most office, retail, light service, and similar workplaces fit here.
• Moderate-risk workplaces: Class A in most configurations, but the number of required attendants increases with workforce size, and Class B may be required for larger workforces.
• High-risk workplaces: Class B is more frequently required, particularly as workforce size grows and travel time to medical aid increases. Tables 2 and 3 spell out the specific thresholds.
• Distant workplaces (over 30 minutes from medical aid), high-risk: Class B is the typical baseline expectation, and at higher workforce thresholds, you may need multiple Class B attendants or supplementary resources.

If you're unsure where your workplace lands, the competent-person assessment is what produces the definitive answer — and if you don't have one on file, that's the first thing to fix.

A common mistake: assuming bigger is always better

If you're certifying first aid attendants for a Saskatchewan workplace, it's tempting to think "let's just go straight to Class B — more training, more capability, more peace of mind." Here's why that often isn't the right call:

• Cost and time. A Class B course is roughly three to four times the time commitment of Class A, with a corresponding cost increase. For workforces where Class A is genuinely sufficient under the Regulations, the marginal investment in Class B is unlikely to pay off in practice.
• Skill use frequency. Class A skills — CPR, bleeding control, choking, common medical emergencies — are the ones that occur most often. Class B's advanced techniques (oxygen, advanced airways, extended patient care) require regular practice or they fade between certifications. If the workplace doesn't actually use those techniques, the investment doesn't translate into retained capability.
• Selection of the right people. The Class B course is significantly more demanding. It works well for workers who are genuinely engaged in being the workplace medic — not as a default upgrade for everyone.

The right strategy for most multi-attendant workplaces: certify a strong baseline of Class A attendants, then identify the right people to take Class B for the situations that require it. A four-person crew with all four trained as Class A is, in most circumstances, better off than the same crew with one Class B and three uncertified workers.

Acceptance across provinces

One question we hear often: "If I get certified in Saskatchewan, does my certificate work in Alberta or BC?" The answer is essentially yes — the Canadian Red Cross Standard First Aid course we run in Saskatoon issues the same certificate that you'd receive from a Red Cross provider in Edmonton or Vancouver. The certifying body is national, and the curriculum is consistent.

What changes is the regulatory framing:

• In Alberta, your Saskatchewan Class A certificate satisfies the Alberta OH&S Code's Standard First Aid requirement.
• In British Columbia, WorkSafeBC's Occupational First Aid system uses its own terminology (OFA Level 1, Level 2, Level 3), and a Saskatchewan Class A certificate may not directly satisfy the OFA Level 1 requirement at BC worksites. If you're moving to a job in BC, check what the specific employer requires.
• For federally regulated workplaces (interprovincial trucking, banking, etc.), a Canadian Red Cross certificate is broadly accepted nationally under the Canada Labour Code.

The reverse is also true: certificates from Alberta, BC, or Ontario are typically accepted as meeting the Saskatchewan Class A or Class B requirement, provided they're from a recognized provider and the training hours meet the Saskatchewan threshold. Your employer's safety officer is the one to confirm with for any specific situation.

Renewal — and what happens when you let it lapse

Class A certificates are renewed through a recertification course taken before the existing certificate expires. The renewal is shorter than the full course (typically 6 to 8 hours) and reviews updated guidelines, refreshes core skills, and tests against the same standards as the original course. The renewed certificate is valid for another three years.

If your certificate has already expired, you generally cannot recertify — you have to take the full Class A course again. Some recently-lapsed situations have flexibility, but as a rule, don't let it expire if you can avoid it. Booking your renewal 60 to 90 days before expiry is the sweet spot.

Class B renewals follow a similar pattern, though the renewal course is proportionally longer given the broader curriculum.

Practical recommendation for most Saskatchewan workplaces

If you're a Saskatchewan employer thinking about how to structure your team's first aid coverage, here's the pattern that works well in most cases:

1. Do the competent-person risk assessment first. Don't book courses before you know what you're required to provide.
2. Build a deep Class A bench. Aim for more Class A attendants than the minimum requires — across all shifts, including weekends and holidays. A workplace where only one person on shift is trained loses its first aid coverage every time that person calls in sick.
3. Identify Class B candidates carefully. If your risk assessment, workforce, or distance puts you in Class B territory, choose people who genuinely want the additional training and have the time to maintain the skills.
4. Schedule renewals in batches. Group certifications run cheaper and waste less time. Don't let attendants drift onto individual renewal calendars unless absolutely necessary.
5. Treat the certificate as the minimum, not the ceiling. Run drills. Practice the skills. The certificate alone, three years old, is no substitute for active competence.

One final thought

The Class A vs Class B distinction can feel like bureaucratic Saskatchewan-specific jargon when you first encounter it. But behind the terminology is a sensible idea: not every workplace needs the same level of first aid coverage, and the regulation reflects the reality that an office on Idylwyld in Saskatoon has different needs than a remote mining camp north of La Ronge. The system gives you two qualification levels and tells you, through the Tables, which one applies to your situation.

Get the assessment right, certify at the right level, and renew on time — and the rest of compliance gets noticeably simpler.
