I am kind of confused. People usually are inadmissible for 5 years for Misrepresentation, your partner was inadmissible since 2015, so he is no longer inadmissible in 2020, so you can sponsor him as your spouse within Canada, elbow come the lawyers say you have no chance?
No I cannot sponsor. It is 5 years from the removal date. He has not been removed yet. The 5 year will count from his deportation. He is under deportation order - I guess you are not. The law says "5 year from execution of removal Order", not misrepresentation (in his case). He was already a PR for a long time before they found out about misrepresentation. So it counts from removal order execution.
