For applicants whose employer is registered in one province (e.g., Ontario) while they physically work at a client's site in another (e.g., Alberta):
- This mismatch is generally not treated as a problem on its own. It's common for consulting or staffing arrangements to have an employer's registered address differ from the client site where the employee actually works day to day.
- Be ready to explain the arrangement clearly. Prepare a short written explanation noting that you are employed by the company (based in Ontario) but physically work at a client's location in Alberta — this pre-empts any confusion from a visa officer reviewing your documents.
- Use your pay stubs to corroborate your actual employer. Pay stubs typically show your employer's registration/code, which helps confirm who is actually paying and employing you, independent of the work-site address on your offer letter.
- Keep both offer letter and pay stub consistent with your explanation so an officer can cross-check the employer identity even though the addresses differ by province.
This is general community experience; if your situation involves additional complexity (e.g., a separate staffing agency), consider getting written confirmation from your employer or a consultant before submitting.
