So you’re in Canada on a study permit, started in a business program, and now you’re thinking about switching to computer science. Big shift — and you’re wondering: do you have to tell IRCC?

Here’s the short answer: if you’re staying within the same DLI (Designated Learning Institution), and your new program is at the same level (e.g., both diploma or both degree), you usually don’t need to apply for a new study permit right away. But it’s not automatic — and it matters for your post-graduation work permit (PGWP).

The key thing IRCC looks at is the length of your new program. If you switch from a two-year diploma to a four-year degree, your PGWP could go from 2 years to 3 years — but only if the new program is at least 8 months long. If it’s shorter, you might get less time on your PGWP.

That said, if you’re switching from a one-year certificate to a three-year bachelor’s, you might need to reapply for a study permit — especially if the new program is longer or at a higher level.

Also, keep in mind: your original GIC and financial proof were based on your first program. If your new program is longer or more expensive, you may need to show updated funds when applying for your PGWP.

What to verify first:
- Is your new program offered by the same DLI?
- Is the new program at least 8 months long?
- Will your PGWP duration change based on the new program length?
- Do you still meet the original study permit conditions?

Questions to consider:
- If you switch to a longer program, will your PGWP be recalculated based on the new duration?
- Can you keep your original start date for the study permit when applying for the PGWP?
- What happens if you switch programs but don’t update your records — could it affect your future immigration applications?

It’s always smart to keep your DLI informed and track your program changes. When in doubt, check with your school’s international student office — they’re usually the best first stop.
