It depends entirely on which route you use, and the difference is measured in months rather than days.
The LMIA route
Before you can apply, you advertise the position nationally and wait out the required period. Then you file the LMIA and wait for a decision. Only then can your candidate apply for a work permit, which is itself a separate queue.
Three sequential stages, each with its own wait.
The LMIA-exempt route
Francophone Mobility removes the first two entirely. There is no advertising requirement and no labour market assessment. You submit the offer of employment through the IRCC Employer Portal, pay the $230 compliance fee, and the portal issues an offer of employment number. Your candidate uses that number to apply.
The employer's part is typically completed within days. What remains is the work permit application itself.
Why permit times vary so much
Processing depends on where the candidate applies from and current volumes at that visa office. IRCC publishes current times and updates them regularly. Times inside Canada and outside Canada differ substantially, and both move.
Anyone quoting you a guaranteed timeline is guessing.
What actually delays employers
In practice the longest stage is often none of the above. It is finding a candidate. Employers spend weeks or months searching before any paperwork begins, particularly when the requirement is French-speaking and the local pool has already been exhausted.
That stage is the one you control, and the one worth shortening first.
FrancoBridge publishes your job across five French-speaking markets and Canada the day you post it.
Processing times change constantly. Check current times on canada.ca. This is not immigration advice.
