Yep, before landing in Canada. I'm in Canada right now and didn't have any problems at entry, but I did get here December 2018.Hi, I am in a similar situation. Did you change DLI before landing in Canada? Are you in Canada right now? Was there any problem at the port of entry?
I applied to study permit with "A" university which will start in September 2020. I want to change it to "B" university which will start in January 2021. I will change the DLI before landing in Canada. Do you think I might have any problem?
Your situation is more complex since both my DLIs had the same start date. You might want to contact the advisor at your DLI and get his advice on that.
