From what I read it seems like the Changing DLI falls under Changing DLI if your outside Canada category and it doesn’t explicitly mention anything if the applicant is already in Canada. However, reading throughout it seems (correct me if I’m wrong)Can you provide the official link from the IRCC website that says you can? Because according to IRCC:
https://www.canada.ca/en/immigration-refugees-citizenship/services/study-canada/change-schools.html
If you change schools and don’t tell us
Your old school will report you as not being registered to study. If this happens:
Changing your DLI if you’re outside Canada
- you’re breaking the conditions of your study permit
- you may be asked to leave the country
- this may prevent you from coming to Canada in the future
- For example, you may not be approved for another study or work permit in the future.
If you change your DLI before coming to Canada and you don’t let us know, you won’t be allowed to board your flight.
If your application is still in progress
You can tell us you changed your DLI by submitting a new letter of acceptance using the IRCC web form.
If your application has been approved
If your application for a study permit has been approved and you change your DLI, you must submit a new study permit application with a new letter of acceptance.
You must also pay all the fees for the new application.
Always rely on the official IRCC statement to be safe.
If one have to change school after landing,
One still has be to enrolled in an approved DLI
Actively studying in the DLI
If above is satisfied the applicant might be eligible to change school without new Study Permit by providing Enrolment letter or something of that sort.
1. That isn’t from official source and if your scroll down the article was modified last in 2019 and a lot has changed in those years. As for your question see my reply above.This rule that says: you need to be actively studying was there since 2019. I have below link that you can see this info was on the IRCC website since 2019 and before. so it is not new.
