You are welcome to check the IRCC website yourself. I have spent so much time on this site helping people understand the new IRCC requirements, if I thought this relates to you, I would tell you. The new policy appears on IRCC's site in relation to students who are still outside Canada and are yet to activate their SP. Below is what is says:
Changing your DLI if you’re outside Canada
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.
You don’t need a representative to change your DLI in your online account, even if you used one to apply for your study permit initially. You just need the study permit application details.

If you are already a student in Canada and need to change DLI, this is the link that pertains to your situation:

If you are still not convinced, you are going to do a Masters so I am sure you are a pro at research
