If you were fingerprinted by the police and the charges were later withdrawn, dismissed, stayed, peace bond, or discharged, it can still show up on an RCMP file.
If it shows up on the RCMP file then it can interfere with your ability to gain employment or travel to the US as there is a red flag on your criminal background check.
Once a file destruction is approved, it will no longer appear on your criminal background check and your CPIC or RCMP file will be clear.
