My daughter yesterday, EU national, applied 22/5, gcms notes confirm Edmonton took case and approved but archived 22/6, official approval 21/10.
I would say to all those with complete applications and who are non visa nationals and are wishing to attend a DLI covid authorised institution, that you should send a webform, include proof of enrolment, include GCMS notes, list the difficulties you have if you're studying online such as time difference, lack of study space, disruption to others, list the consequences of being unable to do certain classes that are obligatory in person for example, ask if you could have your study permit approved NOW so you can book flights to travel. My daughter's letter of introduction was sent at 9.20 Edmonton time yesterday, I'd be confident the webform made a difference in timing of getting the permit approved now.
