Short answer
A WCB clearance letter confirms to a prime contractor that your WCB-Alberta account is in good standing, so they are not left liable for your unpaid premiums. You request it through WCB-Alberta's employer portal, and it is issued when your account is current.
You've won a spot on a prime contractor's project, and now their safety coordinator wants a WCB clearance letter before you mobilize. Or it's the third time this year you've been asked, and you'd like to know what is actually on the letter. Both questions have the same answer, and it's simpler than it looks.
What a clearance letter actually is
A clearance letter is a letter from WCB-Alberta confirming a contractor's account is in good standing. WCB-Alberta's purpose for it is blunt: a clearance clears the company that hired you of liability if you default on premium payments to WCB.
Two terms matter here:
- The contractor or subcontractor is the company performing the work or services — you.
- The principal is the company that hires you and pays for the work — your prime contractor.
Why your prime contractor cares: when they hire a company, they are responsible for that company's workers' compensation insurance unless it has its own valid WCB-Alberta account. They can also be held responsible for unpaid premiums on your account. A clearance letter is the document that takes both risks off their plate.
Timing matters, too. A clearance should be obtained before the contractor starts work, and it also authorizes the principal to release final payment on the contract. That is why you tend to get asked at mobilization — and again before you get paid out.
Keep one thing in mind as you read on: the letter is a report on your account, and accounts get messy through claims and premium problems, not paperwork. That's the ground our WCB claims and cost management service covers; we'll come back to it.
How to get your clearance letter
- Confirm your account is in good standing. The letter is a status report, not a reference. Unpaid premiums or unresolved issues on the account will block it.
- Make sure you are registered with WCB-Alberta. If your business does not have an account, register first — there is nothing to clear until there is.
- Log in to myWCB, WCB-Alberta's employer portal.
- Submit your clearance request with details such as your account number, business name, and the name of the hiring company or project the letter should be addressed to.
- Download it and send it to the prime contractor, and check the clearance period on the letter covers the contract.
When your account is current, the letter is typically available right away through the portal.
What's on the letter, and when it expires
- Your registered business name and WCB account number
- The clearance period — start and end dates
- Confirmation your account is in good standing
- The date of issue
- A verification code the hiring company can use to confirm the letter's authenticity online
A clearance has an expiry, so check that the clearance period runs at least as long as the contract. If it lapses mid-project, expect the prime contractor to ask for a current one. And if you hire subtrades yourself, the same rule applies to you: WCB-Alberta can include multiple contractors on a single clearance letter, and holding clearances for your subtrades is what relieves you of liability for their unpaid premiums.
What blocks a clearance
If a clearance is denied, it means WCB-Alberta cannot confirm your account is in good standing at that time. In practice, that usually means money: unpaid premiums or a balance that has not been resolved. Until it is, no letter is issued — and work can stall at the gate.
There is a jurisdiction question, too. An Alberta clearance letter speaks to your WCB-Alberta account. If the work is being performed outside Alberta, contact the workers' compensation board for that province to find out what it requires.
Keeping the account clear (so this stops being a scramble)
Everything that touches your WCB account eventually shows up in that snapshot, and premiums are experience-rated in Alberta — your accident experience affects what you pay. An unmanaged claim costs you twice: once in the claim itself, and again in the rate that follows.
Employers who produce a clearance on request without drama are usually doing the boring work well:
- Reporting injuries on time — Alberta employers must report a work-related injury to WCB-Alberta within 72 hours of being advised of it.
- Managing claims actively instead of letting files drift.
- Returning injured workers to modified duties where it is safe to do so.
- Keeping premium payments and returns current so nothing lands on the account.
None of that is about the letter. All of it shows up in the letter.
That is the work behind a clean clearance: a healthy account, claims that close properly, and a premium rate that is not climbing because nobody was managing the file. Our WCB claims and cost management service is built for Alberta construction and trades employers — claim reporting, return-to-work, and cost control that keep your account in the shape prime contractors want to see.
