Nobody would tell you to put every dollar you own into one company's stock. Yet a closed work permit does something structurally similar with everything that matters: your income, your legal right to remain, and the Canadian work experience your provincial nomination is scored on all depend on one employer.
Naming that clearly is not alarmism. It is the first step to managing it.
What is actually concentrated
An employer-specific, or closed, work permit authorises you to work for one named employer. If that job ends, three things fail at once:
- Income stops
- Your work authorisation is tied to a job you no longer hold
- The Ontario work experience factor — worth up to 18 points, the single largest in the grid — stops accruing, and the wage and job-offer factors it sits alongside depend on an offer you no longer have
A Canadian citizen who loses a job loses income. You can lose the basis of your entire immigration plan on the same afternoon.
Why it also suppresses your bargaining
The less obvious cost is ongoing rather than catastrophic. When leaving is legally difficult, the normal responses to being underpaid or badly treated are unavailable.
That has a price, and it compounds: wage is a scored factor in Ontario's grid, worth up to 15 points, with real thresholds at $20, $25, $30, $35 and $40 an hour. Staying in an underpaying job is not only a lower salary — it can be a materially lower score, and therefore a longer wait.
If you are within a dollar or two of a wage band, that is a concrete, specific thing to raise at a review — and a rare case where you can point to exactly what the raise is worth beyond the salary itself.
What actually reduces the risk
Know whether your permit is open or closed. Many people are unsure. Check the document. If a spouse holds an open permit, the household risk profile is very different and worth understanding.
Keep the buffer deeper than standard advice suggests. This is the whole argument of the emergency fund guide — a job loss here is a status event, not only an income event.
Understand your options before you need them. There are provisions for changing employers, and in some circumstances for workers in a vulnerable situation. Knowing whether they apply to you takes one conversation with a licensed RCIC while things are calm, and is nearly impossible to research well in a crisis.
Keep your own records. Pay stubs, T4s, a letter of employment, your Notices of Assessment. If the employment relationship ends badly, you may not be able to get documents afterwards — and several scored factors are proven with exactly these papers.
Watch the second income question. Working outside the terms of a closed permit can breach its conditions. Do not assume side work is allowed; check first, because the downside is not a fine.
The uncomfortable summary
You are carrying concentrated risk that you did not choose and mostly cannot diversify. What is left is preparation: a deeper buffer, your own copies of every document, and knowing your options in advance.
That is a smaller set of levers than most people have. It is not nothing, and the people who use them do noticeably better when something goes wrong.
