If you are a permanent resident or a naturalized Canadian citizen (i.e., you came to Canada as a permanent resident and were later granted Canadian citizenship), provide:
The date on which you obtained this status (whichever is more recent)
Your UCI (Unique Client Identifier)/Client ID number)
So now Im not sure it would be mistake or not...
I think it depends on the officer looking at the file. most probably should not be a big deal.
