Use YCOR for the relevant Yukon entity category
The Yukon Corporate Online Registry covers business corporations, partnerships, societies, cooperatives and other registered businesses. Its government guide distinguishes basic services from functions requiring an account. Start with the entity name and examine the type and status returned, especially when a trading name could refer to a sole proprietor rather than a corporation.
A filing key is different from public search access
Yukon’s instructions explain how public searches work and how authorised users submit filings. A private filing key relates to acting for an entity and should not be confused with permission to view a basic record. For cross-border research within Canada, compare any Yukon registration with the original formation jurisdiction before treating it as a separate legal person.
