I filed for study visa in Feb and still waiting for approval.. this was for May intake. But while waiting, I have deferred to sept intake. Should I raise a webform and update my new LOA. Or wait for visa approval and then do this.

Deferring your study permit intake while the application is still pending — do you need to notify IRCC?
If you do it afterwards you will have to extend your study permit afterwards. i suggest do it now.
You don’t need to intimate IRCC if the new intake falls within 150 days from previous intake.
