It was based off best practices from other jurisdictions. I do know that Scotland has higher prison terms. As you mentioned, there are often other criminal offences that go along with coercive control that could potentially have people in jail for longer.
I think this is a really serious offence. I also think five years in prison is a very serious penalty that is significant. Of course, it will be up to this committee and to the House of Commons to decide on the final determination.
