The local police record shows a few things. It will show whether or not it was the right substance, but also whether they have any other records on conviction that were not in the RCMP, and some of those summary convictions could be quite serious. They could be assault, for instance. That's the other reason you do the local police check. The court record would show not just the substance, but whether or not you've completed your sentence and what your sentence was. You don't do those checks just to determine whether it was cannabis or not. There are other reasons for those checks.
