How to Start a Sole Proprietorship in Yukon

What a sole proprietorship is in Yukon

It's you, doing business under your name or a declared trade name — no corporation, no partners, no legal separation between you and the business. Yukon's version is the cheapest registration of the three territories ($25 vs the NWT's $50), and it skips one step the other two territories have: there is no territorial business licence to hunt down, because licences live with the municipalities.

The trade-off in one line: simple and cheap to run, zero liability protection. If the money or the risk gets serious, talk to an accountant about incorporating — and read our federal vs provincial incorporation guide first.

Step 1: File the declaration of business name

If you carry on business under any name other than your own exact legal name, Yukon's Partnership and Business Names Act requires you to file a declaration of business name with Professional and Corporate Affairs. This covers sole proprietorships and partnerships; corporations incorporate under their own statute.

Fill out the declaration form, sign and date it, and submit it with the $25 fee. You can pay by cheque (made out to Government of Yukon), Visa, MasterCard, or American Express, or by cash or debit in person. Filing options:

• Drop it off at the office — 307 Black Street, 1st floor, Whitehorse — or the secure drop box in the lobby;
• Mail it to Professional and Corporate Affairs (C-6), Box 2703, Whitehorse, Yukon Y1A 2C6;
• Fax or email it — provide a phone number so staff can reach you for credit card payment.

The office is open Monday to Friday, 8:30 AM to 4:30 PM; the contact line is 867-667-5314 (toll-free in Yukon 1-800-661-0408, extension 5314).

After your documents are accepted and filed, Corporate Affairs sends a confirmation — the process can take up to 5 business days. The registration is valid for 3 years and must be renewed before it expires; the renewal runs another 3 years. The renewal fee is not published on the public declaration page, so confirm it when you file.

Two name rules worth knowing before you pick: a name reservation is optional — it costs $40 when done online through the Yukon Corporate Online Registry (YCOR) — and business names may not suggest a connection with the Crown, the Royal Family, or a government or First Nation without permission, nor use restricted terms like "College", "Institute", or "University".

The own-name rule

Skip the declaration entirely if you invoice clients as exactly your legal name. The moment you add words, a location, or anything that suggests more than one person ("Amagoalik & Sons", "Yukon Ridge Consulting"), you are into declaration territory. Note that the declaration does not reserve the name for a later incorporation and does not protect it outside Yukon — see the FAQ on trademarks.

Step 2: Get the municipal business licence

Yukon has no general territorial business licence, so this step is municipal:

• Whitehorse: you must apply for and obtain a City business licence before engaging in business inside city limits — it is unlawful to operate without one. Licences run on a calendar-year basis and expire December 31. For licence questions, the yukon.ca declaration page itself points you to the City of Whitehorse at 867-668-8346.
• Other communities: Dawson, Faro, Watson Lake, Carmacks, Haines Junction, Mayo, and Teslin each issue their own municipal licences. If your community is not on that list, contact the community government — unincorporated communities generally have no licence office.
• Working across communities: if you operate in two or more municipalities, buy an inter-municipal licence from your home municipality rather than a separate licence in each place. You must already hold a valid home-municipality licence, and food businesses are largely excluded because each community sets its own food regulations.

Sector-specific permits (liquor, vehicle-for-hire, health-inspected premises) come from other regulators entirely — run your trade through the BizPal permit search (bizpal.ca) to catch them.

Step 3: Register with the WCB only when you hire

Yukon's Workers' Safety and Compensation Board is the workers'-compensation authority:

• If you hire anyone, you are an employer and must register with the board within 10 calendar days of employing them. Late registration draws an administrative fee of 10% of the premiums that would have been payable, plus interest. Employers file an Employer Payroll Return every year by February 28.
• Sole proprietor with no workers: you are not automatically covered and you do not register. You may apply for optional personal coverage if you want the board's protection for yourself.

This is simpler than the NWT/Nunavut rule (the 10-day WSCC registration trigger there applies to the business itself) — in Yukon the only trigger is hiring.

Step 4: CRA business number and 5% GST

This leg is national, and Yukon's is the simplest version:

• Get a free CRA business number through the CRA's Business Registration Online — the root identifier for GST, payroll, and import/export accounts.
• Yukon is GST-only: 5%, no territorial sales tax, no HST. Your invoices show 5% GST with your business number, and that's the whole sales-tax picture.
• The $30,000 small-supplier threshold applies the same as everywhere else: over $30,000 in taxable sales across four consecutive calendar quarters (or $30,000 in one quarter) and registration becomes mandatory.

If you cross the threshold, read our GST/HST registration guide for the route-by-route walkthrough — and note that registration timelines differ by method (the online route is the fast one), which we now cover in that guide's timeline section.

Startup checklist

• Declaration of business name filed with Corporate Affairs (Whitehorse) — or confirmed exempt as own-name-only
• Name reservation considered ($40 via YCOR) if the name matters before you file
• Municipal business licence from the community where you operate (Whitehorse: inside city limits; other communities: their own office) — or inter-municipal licence if you work across communities
• WCB registration (within 10 calendar days of your first hire; optional personal coverage if you're solo)
• CRA business number obtained (free)
• Tracking revenue against the $30,000 rolling threshold; charging 5% GST when registered
• Invoices show GST separately with your business number; a fixed slice of every invoice set aside for income tax + CPP
