What are BC's compulsory (Skilled Trades Certification) trades?

Skilled Trades Certification is in effect for seven electrical and mechanical trades: Construction Electrician, Industrial Electrician, Powerline Technician, Pipefitter/Steamfitter, Refrigeration and Air Conditioning Mechanic, Sheet Metal Worker, and Gasfitter (Class A and B). Workers in these trades must be a registered apprentice, a certified journeyperson, or registered with SkilledTradesBC as a Trade Qualifier or Uncertified Experienced Worker, and employers are responsible for ensuring it.

Do I need COR to bid public work in BC?

COR is a voluntary program, but in B.C. it's widely recognized by owners and general contractors as a prequalification signal, and many procurement teams prefer or require it for commercial construction. In B.C., COR is issued by WorkSafeBC and delivered through certifying partners — the BC Construction Safety Alliance (BCCSA) is the certifying partner for the construction industry.

How does COR certification work in British Columbia?

You implement an occupational health-and-safety management system and pass a certification audit through a certifying partner such as the BCCSA. COR is valid for three years with annual maintenance audits, and re-certification follows. There are Small (19 or fewer employees) and Large (20+) streams, and COR-certified employers are considered for a WorkSafeBC incentive the year after certification.

Skilled Trades Certification and prequalification for BC public construction

British Columbia has a requirement most provinces don't — compulsory Skilled Trades Certification — plus COR, WorkSafeBC, insurance, and bonding. What you need to be eligible for BC public tenders.

British Columbia adds a wrinkle to public bidding that most provinces don't have: certain trades are compulsory, meaning the people doing the work must be certified, not just competent. Layer the usual safety, insurance, and bonding prequalification on top, and "being eligible" in B.C. is a slightly longer checklist than next door. Here's what it takes.

Skilled Trades Certification (compulsory trades)

B.C.'s Skilled Trades Certification (STC) is in effect, and it applies to seven electrical and mechanical trades:

Construction Electrician
Industrial Electrician
Powerline Technician
Pipefitter/Steamfitter
Refrigeration and Air Conditioning Mechanic
Sheet Metal Worker
Gasfitter (Class A and B)

Anyone working in these trades must be a registered apprentice, a certified journeyperson, or registered with SkilledTradesBC as a Trade Qualifier or Uncertified Experienced Worker — and the employer is responsible for making sure every worker qualifies. If your scope touches these trades on public work, this is non-negotiable. (Note a policy change taking effect August 1, 2026: experienced workers seeking certification are no longer automatically placed at the final level of their trade — confirm the current process with SkilledTradesBC.)

COR through the BCCSA / WorkSafeBC

A Certificate of Recognition (COR) is the safety credential public buyers look for. In B.C.:

COR is issued by WorkSafeBC and delivered through certifying partners; the BC Construction Safety Alliance (BCCSA) is the certifying partner for the construction industry.
It's voluntary, but widely treated as a prequalification signal — many B.C. procurement teams prefer or require it for commercial construction.
It's valid for three years, with annual maintenance audits and re-certification after. There are Small COR (19 or fewer employees) and Large COR (20+) streams.
COR-certified employers are considered for a WorkSafeBC incentive the year after certification.

As with every safety certification, start early — building and auditing the program takes time.

WorkSafeBC registration

Register with WorkSafeBC and keep your account in good standing. Buyers and prime contractors verify coverage before work starts and before final payment, because hiring an uncovered contractor can transfer liability to them.

Insurance and bonding

Commercial general liability (CGL) — limits depend on the project; public work commonly asks for $2 million to $5 million. Add automobile and, where design is involved, professional liability.
Surety bonds — a bid bond with the tender, and performance and labour-and-material payment bonds if you win. Build bonding capacity with a surety before a project requires it.

Registration and the B.C. portals

B.C. work is spread across more places than most provinces. Register where it matters:

BC Bid — the provincial portal; some functions need a Business BCeID. See BC Bid explained.
CivicInfo BC and the big cities' own systems for municipal work — compared in BC Bid vs CivicInfo vs CanadaBuys.

The short version

Before you chase B.C. public tenders, make sure you have:

Workers in compulsory trades certified or registered with SkilledTradesBC
COR through the BCCSA (or your certifying partner)
WorkSafeBC coverage in good standing
CGL insurance (plus auto, and professional where needed)
A surety relationship for bid and performance bonds
BC Bid registration (Business BCeID) and the municipal feeds you need

Once eligibility is handled, the question at each tender is whether the work fits — see our go/no-go framework and the complete B.C. bidding guide.

One feed for the work that fits

Prequalification gets you eligible; finding the right tenders across BC Bid, CivicInfo, the major cities, and CanadaBuys is the other half. Cornerstone Contracts pulls them into one daily feed, scored to your trade, service area, and project size, with a compliance-aware draft proposal for any tender you pursue.
