Prevention Program vs Action Plan: Which One Does Your Quebec Business Need?

Your accountant mentions an "action plan." A consultant quotes $3,400 for a "prevention program." The CNESST website talks about both. And you, running a 14-person business in Brossard, still don't know which document the law actually expects from you.

The answer comes down to one number: 20 workers. Below it, Quebec's OHS rules require an action plan. At 20 and above, a prevention program. But that threshold hides a few traps, and in the prevention program vs action plan question, guessing wrong costs you either way. Too little exposes you to a fine. Too much means thousands of dollars in consulting you didn't need.

Count with me.

What's the difference between a prevention program and an action plan?

The OHS action plan is the lighter document for Quebec establishments with fewer than 20 workers: risk identification, corrective measures, a timeline, and an annual update. The prevention program, mandatory from 20 workers up, adds worker training, protective equipment maintenance, and health surveillance, and comes with a health and safety committee.

Both documents share the same skeleton. In each case, the law asks you to identify the risks present in your workplace across six categories (physical, chemical, biological, ergonomic, psychosocial, and safety-related), then document how you'll eliminate them or, failing that, control them.

The difference is depth.

A prevention program covers ground the action plan never asks about: health surveillance measures where exposure justifies them, personal protective equipment identified per workstation, training and information programs for workers, and preventive maintenance of protective equipment. It also carries a heavier participation structure. At 20 workers, you form a health and safety committee with worker representatives, meetings, and minutes. Under 20, you designate a single liaison officer, who can be you or a trained employee.

In practice: a well-built action plan runs 8 to 15 pages for an office or a store. A prevention program for a fabrication shop easily passes 30 pages.

How do you know which one your business must produce?

Since October 1, 2025, an establishment with fewer than 20 workers must produce an OHS action plan and designate a liaison officer. At 20 workers or more, the requirement becomes a prevention program plus a health and safety committee. The count is per establishment, not per company, and it includes part-time staff.

Three details change everything:

• You count workers, not "full-time employees." Part-timers, summer students, and agency temps all enter the calculation. A restaurant with 11 regulars and 10 weekend servers is above the threshold.
• The count is per establishment. A company of 30 people split across two branches of 15 produces two action plans, one per address. Flip it around: a single warehouse of 22 workers requires a prevention program even if head office has 4 employees.
• The threshold also picks your participation structure. Under 20, a liaison officer. At 20 and up, a committee, which means a rhythm of meetings and minutes that a solo owner rarely anticipates.

These obligations come from the modernization of Quebec's OHS regime started by Bill 59 (Projet de loi 59) and written into the Act respecting occupational health and safety. Before October 2025, most offices, stores, and small shops flew under the radar because prevention mechanisms only targeted certain priority sectors. Not anymore. A 6-person accounting firm in Brossard now carries the same documentary obligation as a machining shop, scaled to its level of risk.

While building PlanSST, I talked with dozens of SMB owners on Montreal's South Shore, and the confusion between these two documents came up in almost every conversation. The most common case: an owner with 12 or 15 employees holding a consultant's quote for a "full prevention program" at $3,000 or more, when the law only asks them for an action plan. Nobody had told them the threshold existed.

If you want the full picture of what applies at your size, our Bill 59 compliance checklist for Quebec SMBs walks through every obligation item by item.

What goes into an OHS action plan?

A compliant action plan contains at minimum: risk identification by category for your specific workplace, the measures planned to eliminate or control each risk, a completion timeline with named owners, and a record of its annual update. The document stays internal, but it has to be presentable during an inspection.

Concretely, the CNESST expects four blocks:

1. Risk identification. Not a generic list copied from the internet: your risks, in your space. The badly laid-out service counter, the solvent in the back room, the workload spike during tax season.
2. Corrective measures. For each risk, what happens next? Elimination first, control second, protective equipment as the last resort.
3. Timeline and owners. A measure without a date and a responsible name doesn't exist in an inspector's eyes.
4. Follow-up. The date of the last update and what got done since the previous version.

I've seen the counter-example up close. The owner of a 9-person catering kitchen in Longueuil showed me what a supplier had sold her as an "OHS plan": a 35-page template with her company name mail-merged in, whole sections on scaffolding work she'll never do, and nothing on burns, knife handling, or the walk-in freezer. She'd paid $1,600 for a document that would have hurt her file in an inspection rather than helped it. What struck me most: she suspected it all along. She just never had a week to redo it.

What does a prevention program add on top?

The prevention program includes everything in the action plan and layers on four extra components: health surveillance of workers where the risk justifies it, maintenance standards for protective equipment and systems, training and information programs, and personal protective equipment identified position by position.

This is where the step up gets real. A prevention program asks you, for example, to document which OHS training each job category receives, when, and from whom. To keep a maintenance log for protective equipment: extinguishers, ventilation systems, machine guards. Medical surveillance needs planning too, if workers are exposed to contaminants like silica or solvents beyond regulatory limits. And to keep the health and safety committee alive: agendas, meetings, follow-up on recommendations.

There's a calendar trap too. If your business is growing and you'll cross 20 workers this year, structure your action plan now as the embryo of a future prevention program. Owners who hire their 20th person mid-high-season have no appetite for building a committee and three new registers at the same time.

One clarification that saves people a headache: the psychological harassment prevention policy is a separate obligation that comes from a different law, and it applies no matter your headcount. Our overview of Quebec OHS requirements for small businesses covers how the pieces fit together.

What happens if you have neither?

During an inspection, having no action plan and no prevention program exposes an employer to a correction notice with a firm deadline, then to fines starting at $2,000 per day of offence for a corporation under s. 236 of the OHS Act, and reaching $15,000 to $60,000 when a violation endangers a worker under s. 237. The document is almost always the first thing an inspector asks to see.

CNESST inspectors don't only show up after an accident. An employee complaint, an anonymous report, or a sector-wide campaign is enough. As of August 2026, almost a year after the small-establishment obligations took effect and with the October 1, 2026 full-implementation deadline approaching, the educational grace period is winding down. We broke down the full penalty mechanics, including how repeat offences multiply, in how Bill 59 penalties actually work.

Your document is your first line of defence. A dated action plan, adapted to your premises and partially executed, demonstrates diligence even when everything isn't finished. The opposite (no document, or a generic template nobody ever opened) puts the conversation on a very different footing. The official details on prevention mechanisms by establishment size are on the CNESST website, and our guide on what to expect during a CNESST inspection shows how the visit actually unfolds.

One nuance worth knowing: sending the action plan to the CNESST is not required — unlike the 20-plus prevention program, which does get transmitted to the CNESST periodically. You keep the action plan in-house, current, ready to show. That's good news (no filing bureaucracy) and a trap at the same time, because without an external deadline, the document slides to the bottom of the pile for months.

Frequently Asked Questions

What is the difference between a prevention program and an OHS action plan in Quebec? The action plan is the lighter document required of Quebec establishments with fewer than 20 workers: risk identification, corrective measures, and a timeline. The prevention program applies at 20 workers and up, adding training plans, protective equipment maintenance, and health surveillance, plus a health and safety committee instead of a liaison officer.

My business has fewer than 20 employees. Which document do I need? An OHS action plan, mandatory since October 1, 2025 for every Quebec establishment with fewer than 20 workers. It must identify workplace risks across six categories, set out measures to eliminate or control them, and be updated at least once a year. You also need to designate a liaison officer.

How do you count the 20 workers that decide between the two documents? Count per establishment, not per company, and include part-time, temporary, and seasonal workers. A company with two shops of 12 people each produces two action plans, not one prevention program. A single warehouse of 22 workers needs a prevention program even if head office has only 4 employees.

Do I have to send my action plan to the CNESST? No. Sending it in is not required: the action plan stays an internal document. It does have to exist in writing, be current, and be available on request during an inspection. To an inspector, a plan that is missing or two years out of date reads the same as no plan at all.

What fine does a Quebec small business risk without an action plan? CNESST fines for a corporation start at $2,000 per day of offence under s. 236 of the OHS Act and reach $15,000 to $60,000 when a violation endangers a worker (s. 237), with amounts doubling for a repeat offence. An inspector can also issue a correction notice with a firm deadline first.

Where to start this week

Count your workers per establishment, part-timers included. Under 20: your target is an OHS action plan and a liaison officer. Twenty and up: a prevention program and a committee. Either way, the first step is identical, and it's the one owners postpone: identifying your real risks, category by category, in your own space.

You don't need a $3,400 consultant for an 8-person office. Answer PlanSST's questionnaire about your workplace (around 30 questions, most owners finish in about 30 minutes), and we turn it into a documented action plan built on your actual risks, ready to show an inspector.
