Can I open a sole proprietorship while on a work visa?
You can file to start a sole proprietorship, but whether you may actually operate it on your current work status depends on whether the business activity stays within that status's authorized field.

What you need to know
Requirements & exceptions
- Tax registration and immigration authorization are separate.
- Side activity outside the status can require permission.
- If the business becomes your principal management activity, consider Business Manager.
Documents
- Government-issued ID or provider-required identity documents
Likely cost
No separate government fee merely for having this employment arrangement. If immigration permission/status change is required, the applicable ISA procedure fee applies; tax/social-insurance contributions are separate.
Where to act
Employer/contracting client plus the Regional Immigration Services Bureau if immigration authorization or notification is required.
