Not every program leads to a work permit anymore
This is the biggest trap, and it has gotten sharper in the last couple of years.
It used to be simple: graduate from almost any Canadian college or university and get a post-graduation work permit. That is no longer true. The rules have tightened, and now two things matter, not one.
First, the institution. It has to be an eligible designated learning institution, and not every school on the list leads to a work permit for every program.
Second, and this is the new part, the field of study. For college and other non-degree programs, your specific field now has to align with what the rules recognize as eligible. Some programs that were fine a few years ago no longer lead to a work permit at all. Bachelor's, master's, and doctoral degree graduates are generally not subject to the field-of-study restriction, but for college and non-degree credentials, the field is now decisive.
Picture a student who picks a program mainly because it is affordable and easy to enter, without checking whether that specific program is eligible for a post-graduation work permit. The program is real, the school is real, and the student graduates successfully. Then they apply and learn the field does not qualify. No post-graduation work permit through the route they assumed, which means no Canadian work experience through that plan, and the study-to-PR path they were quietly counting on is gone.
That is why "is this school a DLI?" is no longer enough of a question. The real question is whether this specific program, at this specific institution, actually leads to a work permit and a future.
