Hi, I am on work permit and already in Canada. The police record is needed post you are selected in the draw (you have 90 days to prepare for ur papers) for any place you’ve stayed at, for more than 6 months at a stretch. Specifically for Canada police verification, you just need to visit their designated locations (I’ve mentioned one in the above thread) and provide them your ITA reference number. They will take ur picture and biometric on-site in their office and directly send your information to the police to process and that gets attached to ur PR profile.
