Every application you make to IRCC is logged and “promoted” within the GCMS system. And can be cross referenced by an officer at any point.How sure are you about this. I made a mistake about my employment so I withdrew my profile and put in a new one would this be a problem potentially with misrepresentation.
If you made a mistake previously, you can always include an LOE with your latest application if you are worried some details won’t match up.
