How to open a WCB Alberta account as a contractor

Who has to register, the 15-day rule when you hire, the $200 that unlocks your first clearance letter, what it costs by trade, and the annual return.

October 10, 2026

Do you need one?

WCB Alberta asks a business to register if any of these is true:

  • you employ workers, full-time or part-time,
  • you want personal coverage for yourself as an owner, director or partner,
  • you need a clearance letter.

The third one is the reason most solo trades end up registering. A GC asks for a clearance letter, and WCB says plainly that to get a clearance for yourself or your company as a contractor, you need a WCB Alberta account.

And if you hire, the deadline is short: WCB wants to hear from you within 15 days of your first worker's start date, or a late registration penalty applies.

How to apply

Apply online through WCB's account registration at wcb.ab.ca/application. It asks for:

  • your legal business name, and your trade name if you use one,
  • your CRA business number if you have one (WCB uses it for statistics),
  • what your business does, which decides your industry and your rate,
  • your estimate of what you will pay workers this year,
  • whether you want personal coverage, and how much.

WCB says a representative will contact you within five business days.

What it costs

Your premium is your workers' insurable earnings, plus any personal coverage, times your industry's rate per $100. The minimum annual premium on any account is $200.

A few 2026 industry rates per $100 of earnings, from WCB's rate table:

Industry2026 rate
Electric Wiring$1.83
Floor Coverings$2.19
Painting/Decorating$3.81
Concrete Construction$4.31
Drywall/Plaster/Stucco$4.69
Construction Framing Contractor$5.37
Roofing$5.51

Your own rate can move from the industry rate: WCB reviews your claims and your industry's over the following three to five years and may apply a discount or a surcharge.

For yourself as an owner, see WCB personal coverage: what it pays, and what it costs in your trade.

What you owe WCB once you are in

  • An annual return by the last day of February: what you paid workers last year, and your estimate for this year. Late, and a penalty of 10% of the net premium applies, plus daily interest.
  • Keep the estimate honest. WCB gives you a 50% margin. If your actual earnings come in above 150% of your estimate, a 10% penalty plus interest is charged on the premium above that line. Revise the estimate in myWCB before December 31 if the year is bigger than you thought.
  • Pay on time. Overdue amounts carry monthly interest at prime plus 8%.
  • Report injuries within 72 hours of being told about them.
  • Personal coverage lapses if premiums go unpaid, and paying later does not restart it: you have to call WCB.

Frequently asked

Do I need a WCB account if I work alone?
If you need a clearance letter or want personal coverage, yes. WCB says a contractor who needs a clearance for themselves or their company needs a WCB Alberta account.
How soon do I have to register after hiring?
Within 15 days of your first worker's start date, or a late registration penalty applies.
Why can't I get a clearance letter on my new account?
WCB requires an initial payment of $200 before a newly issued account qualifies for clearances. It is applied to your first invoice.
When is the WCB annual return due?
By the last day of February, reporting last year's earnings and this year's estimate. Late returns carry a 10% penalty plus daily interest.
