If you were removed then you would need to go through the ARC process, pay the ARC fee and also pay back the costs of the flight to remove you from Canada.
If you don't think you need an ARC you can certainly try applying for an eTA or TRV without the ARC and see what happens. Your choice.
My friend was removed from canada with an exclusion order and they have not provided any documentation in respect to certificate of departure. Can we apply for it or how do we get it.
