Newfoundland and Labrador is one of Canada's most distinctive places to run a trade. HST is 15%, the builders lien must be preserved within just 30 days, there are only five compulsory trades, and the big resource projects run on a union-access model that locks out unaffiliated self-employed trades. This guide walks through what a self-employed tradesperson actually needs to track.
Sales tax: HST 15%
Newfoundland and Labrador charges 15% HST (5% federal plus 10% provincial). Register for GST/HST once taxable revenue passes $30,000 over four consecutive quarters, within 29 days of the effective date. The quick-method remittance rate for services supplied in the province is 10.0%.
Minimum wage
The minimum wage is $16.35 an hour (set 1 April 2026). Build it into any quote where you carry a labourer or apprentice.
Builders lien: a short 30-day clock
The province runs the Mechanics' Lien Act, largely unchanged since 1970, and its deadlines are tighter than most reformed provinces.
- Preserve (register): within 30 days of your last day of work, last supply of materials, or completion of the service. That 30-day window runs from your actual last day on site, not from substantial completion of the whole project. This is the single most important deadline to track in this province.
- Perfect: within 90 days of the last day the lien could have been preserved, by starting an action and registering a Certificate of Action.
- Holdback: 10% of the contract price, held until 30 days after completion.
There is a large-project carve-out: on contracts over $20 million running more than a year, the holdback can be released annually rather than at the end. The Act has no modern statutory trust regime, a known gap the province consulted on in 2024 but has not yet legislated.
Limitation period: 30-year long-stop
Newfoundland and Labrador has a longer basic limitation period (six years) than the two-year provinces, with an ultimate limitation of 30 years. So a defect claim can surface far later here than in Ontario or BC. Build that into how long you keep your job records and as-builts.
Prompt payment: none
There is no prompt-payment legislation and no mandatory adjudication. The province ran a consultation in 2024 but no bill has been introduced. The lien is your only statutory payment tool, which makes that 30-day clock all the more important.
Workers compensation: WorkplaceNL
WorkplaceNL (workplacenl.ca, 1-800-563-9000) is the board. Every employer doing work in the province must register, and that includes a principal who subcontracts work even with no direct employees. A solo sole proprietor or partnership with only the owners working need not register until an outside worker is hired or work is subcontracted.
The 2026 average assessment rate is $1.73 per $100 of assessable payroll. The maximum assessable earnings figure is $80,935 per worker. A construction safety levy of $0.10 per $100 funds the NL Construction Safety Association on top. Individual construction rates by NIC code are published in the full WorkplaceNL rate manual: pull your own classification rather than using the average. Report serious injuries immediately to the 24-hour line, and file the employer's report within 72 hours.
Licensing: five compulsory trades
There are exactly five compulsory trades, administered by the Apprenticeship and Trades Certification Division (ATCD): Construction Electrician, Residential Electrician, Boom Truck Operator, Mobile Crane Operator, and Tower Crane Operator. To work in any of these you need a Certificate of Qualification or to be a registered apprentice. Note electricians and crane operators dominate the compulsory list; most other building trades are voluntary here. Exam fees were eliminated in Budget 2025.
Small claims: $25,000
The Small Claims Court limit is $25,000. Prejudgment and post-judgment interest is a flat 2% a year (Judgment Interest Order, 2026), which is low, so do not expect interest to compensate you much for a slow-paying client. Filing fees are $50 up to $499.99 and $100 from $500 to $25,000.
Quirks worth knowing
- The 30-day lien window is the trap. Most contractors arriving from other provinces assume 60 days. It is half that here, with no substantial-performance extension.
- Megaproject access is union-gated. Offshore oil (Hibernia, Terra Nova, White Rose, Bay du Nord) and Labrador hydro run under Special Project Orders that prescribe which unions and contractor associations get the work. A self-employed tradesperson who is not affiliated generally cannot access these sites directly; the route in is via a contractor holding a project agreement.
- Low judgment interest. At a flat 2%, suing for a slow payment earns you little extra. Lien first, sue second.
Common mistakes
- Missing the 30-day lien deadline. It is the shortest in Atlantic Canada and runs from your last day on site.
- Banking on offshore work as a one-person band. Without union affiliation or a contractor relationship, the big projects are closed to you.
- Underkeeping records. With a 30-year ultimate limitation, hold your job files far longer than two years.
