Yukon is its own world inside the North. It charges only 5 percent GST with no provincial tax, pays one of the highest minimum wages in Canada at 18.51 dollars an hour, and runs its own workers comp board, the WSCB, entirely separate from the WSCC that covers the Northwest Territories and Nunavut. Its builders lien law is old and short: a 30-day general preservation window with no substantial-performance extension, which catches out almost everyone arriving from the south. There is no prompt-payment law. This guide goes deeper than the combined territories summary on what is specifically Yukon.
Sales tax and the mileage top-up
Yukon has no provincial sales tax or HST. You charge only the 5 percent federal GST, register once taxable revenue passes 30,000 dollars over four consecutive quarters, and recover GST on your business inputs as normal. The CRA per-kilometre rate is 4 cents higher in the territories, so for 2026 it is 77 cents for the first 5,000 km and 71 cents after, against 73 and 67 cents in the provinces. Claim the higher northern rate on your business travel.
Minimum wage
Yukon's minimum wage is 18.51 dollars an hour, among the highest in the country. It is the floor for any employee you put on the books, and northern wages, freight and accommodation all push a Yukon quote well above a southern one.
Builders lien: the short 30-day clock
Yukon runs the Builders Lien Act (RSY 2002, c.18), older legislation that has not been replaced by a modern Act, and its deadlines are materially shorter than the reformed provinces. Treat the dates as hard.
- General preservation (non-wage claimants): 30 days from completion of the work or from supplying or placing machinery. Miss it and a supplier or subcontractor loses lien rights entirely. There is no substantial-performance concept to extend the clock.
- Wage claims: 30 days from the last day's labour, with the total period not to exceed 60 days from the last day's labour.
- Perfection: the lien ceases to exist 90 days after the work is completed, materials are furnished or wages are earned, unless an action is commenced and a certificate is registered.
- Holdback: 10 percent, which the owner may retain for 30 days after completion.
The 30-day general window is the single biggest trap in Yukon. Contractors used to a 60-day rule routinely lose their lien rights by treating Yukon like a southern province. Calendar the 30 days the day you finish on site.
Prompt payment: none
Yukon has no prompt-payment legislation and no adjudication regime. Payment timing is governed by your contract and the lien remedy alone, which makes the short 30-day clock all the more important to protect.
Workers comp: the WSCB, not the WSCC
This is a key distinction from the other two territories. Yukon has its own board, the Workers' Safety and Compensation Board (WSCB), based in Whitehorse and operating under the Workers' Safety and Compensation Act in effect since 1 July 2022. It is entirely independent of the WSCC that covers the Northwest Territories and Nunavut, and they share no administrative platform. Register with the WSCB, not the WSCC, before you put workers on a Yukon site, and get a clearance to show the project owner.
Yukon uses rate groups rather than a single average, and construction is split into Medium and High groups, both of which rose for 2026. The maximum annual earnings figure for 2026 is 107,599 dollars. Construction rate groups sit well above the all-territory benchmark, so confirm your specific group with the WSCB rather than budgeting on an average. Fall protection is required at 3 metres, and a written fall protection plan is required where a fall of 7.5 metres or more could occur, a higher written-plan trigger than the 3-metre trigger used in the Northwest Territories and Nunavut.
Trades, codes and permits
There is no territorial general contractor licence, but general contractors must hold a valid contractor's licence and municipal permits, for example in the City of Whitehorse, require contractor registration with proof of general liability insurance. Trade certification is administered by Yukon Apprenticeship Training under the Department of Education, and regulated trades include gas fitters (who also need a licence), electromechanics and oil burner mechanics. Red Seal endorsements are accepted; verify a credential by email to apprenticeship@yukon.ca. Yukon adopted the National Building Code 2020 with territorial variations, in force 1 April 2023, so build to NBC 2020 here.
Common mistakes
- Assuming a 60-day lien window. Yukon's general window is 30 days with no extension. It is the trap.
- Registering with the WSCC. Yukon is covered by the WSCB; the WSCC covers only the Northwest Territories and Nunavut.
- Pricing like the south. Freight, accommodation, the higher minimum wage and the 4-cent mileage top-up reshape the number.
