I will try to answer, but with apologies and respect for the committee, this is not an area I have tremendous expertise in.
I think our understanding is that the crimes committed in the local jurisdictions are still the matters of the local police, and they would work co-operatively with local police in other jurisdictions where the same or similar offences had taken place by the same potential suspect.
It's not my understanding, but I would recommend that perhaps you invite the RCMP to ask them this question, that because a crime may cross provincial borders that would give the RCMP enforcement jurisdiction.
