"WCB compliant" shows up on almost every commercial cleaning website in Manitoba — including ours. Almost nobody who hires a cleaning company checks what it means, and fewer still verify it. That's a problem, because a WCB compliant cleaning company isn't a nice-to-have credential like a fancy logo. It's the line between a vendor's workplace injury being their problem and it becoming yours. Manitoba's Workers Compensation Board says so directly: janitorial is one of the industries it specifically tells businesses to check clearances on before work starts and before any payment is made.
Here's what the term actually means, what happens when a cleaning contractor isn't covered, and how to verify any vendor's status yourself — for free, in a few minutes.
What WCB coverage actually is
The Workers Compensation Board of Manitoba runs a no-fault insurance system funded by employers. Businesses register with the WCB, report their payroll, and pay premiums. In return, when a worker is injured on the job, the WCB covers wage loss and healthcare costs — and the worker generally can't sue the employer or the business where the injury happened, because compensation flows through the system instead.
"In good standing" means a business has done its part: it's registered, its payroll reporting is current, and its premiums are paid. That's what a clearance letter confirms. "WCB compliant" on a cleaning company's website should mean exactly this — registered and in good standing — not something vaguer.
Why an uncovered cleaning crew becomes your problem
This is the part most businesses don't know, and it's not fine print — it's the WCB's stated position.
If you hire a contractor who is not in good standing with the WCB, the board can treat that contractor's people as your workers — what the WCB calls "deemed workers." Two things follow from that:
Their payroll becomes your payroll. You become responsible for including the labour portion of the contract in your own reported assessable payroll. You're paying WCB premiums on your cleaning vendor's labour because the vendor didn't.
Their injuries become your reports. Any workplace injury that happens while that contractor is working for you is yours to report — and injury claims are a factor in how assessment rates move. A cleaner who slips in your stairwell at 11 p.m. stops being an abstraction very quickly.
And there's no clawing it back afterward: the WCB is explicit that you cannot deduct earnings from a deemed worker to offset what their status costs you. The time to deal with this is before the contract is signed, not after the incident.
The clearance letter: how to actually verify a vendor
The good news is that checking takes minutes and costs nothing. The WCB runs an Online Clearance Request System with a public search — no account needed, available around the clock. You search the company, and the system tells you whether it's in good standing and lets you request a clearance letter documenting it.
The WCB's guidance is specific about timing: get clearance information before work commences and before any payment is made. For an ongoing service like cleaning, it's reasonable to re-check periodically — status isn't permanent, and a company that was in good standing at signing can fall out of it. If you manage multiple vendors, the WCB also offers a registered-user version of the system that keeps a stored list of your contractors and emails you when a clearance status changes — genuinely useful for property managers running a dozen trades across a portfolio.
One more wrinkle: if you search and can't find the company at all, that doesn't settle anything by itself — it may mean they're not registered, or that they're not required to be. The WCB's Assessment Services line (204-954-4505 in Winnipeg) can tell you which it is. What you shouldn't do is shrug and assume it's fine.
What to ask a cleaning vendor before you sign
A legitimate cleaning company makes this easy. Two questions do most of the work:
"Can you provide your WCB account number or a current clearance letter?" There's no good reason to hesitate on this. A vendor that stalls, changes the subject, or promises to "get you that later" is telling you something. This belongs on the same pre-hire list as insurance and references — we walk through the full list in our guide to choosing a commercial cleaning company.
"Do you use subcontractors, and do you check their clearances?" Some cleaning companies quietly sub out nights, weekends, or whole buildings. If the company you hired subs the work to a firm with no coverage, the chain of responsibility gets messy — and you want to know your vendor is running the same clearance checks on their subs that you're running on them.
WCB compliance and insurance are two different things
They get blurred together constantly, and they shouldn't be. WCB coverage protects against the costs of a worker's injury. It does nothing about the floor their equipment scratched, the server their mop bucket met, or a claim from a visitor who slipped on a wet floor after hours. That's what commercial general liability insurance is for.
A properly set up cleaning vendor carries both, and can show proof of both. At Shift Clean that's WCB coverage plus $2M in liability insurance — but the point isn't our paperwork, it's that you should ask for everyone's, ours included.
Where this matters most
Every commercial building benefits from a covered vendor, but the stakes climb with the environment. In warehouse and industrial facilities, cleaning crews work around racking, loading docks, machinery, and floor hazards that office towers don't have — the same reason industrial sites routinely demand clearance letters from trades is the reason they should demand them from cleaners. Multi-tenant and property-managed buildings are the other hot spot: an uncovered vendor working across common areas creates exposure the property manager may not even know they're carrying.
If your current vendor was hired years ago and nobody has checked their status since, that five-minute search is worth doing this week.
A written scope from a company you can verify
Verifying WCB status tells you a vendor is legitimate. It doesn't tell you whether their quote reflects your actual building — that takes a documented scope. Our facility auditor visits your space, takes the measurements and counts, and documents the scope your written estimate is built from. What goes into that price is exactly what our commercial cleaning cost guide explains.
