Yes, in all cases that I know of, the criminal record has followed the person. It would be terrible if a person built up a long criminal record and could get rid of it other than by pardons, and this is the usual thing.
Could you imagine working all your life, reaching age 60 and building up all your pension credits and changing your name, and all of a sudden you've lost your pension? Your SIN number is changed. All your CPP credits follow you, your child tax credits. The things that should follow you do follow you. That's what the RCMP is supposed to do. And they should, and they do, transfer the criminal record. It's essential.
