As I mentioned, a risk assessment is done at the bail hearing. There is a provision under subsection 515(3) of the Criminal Code that was added through former Bill C-75 and that now requires judges, before making any bail decision, to look at the criminal record of the accused and at whether the accused was charged with domestic violence. I think the criminal record is really key to getting the history of offending and whether there's a pattern of violence there that is likely to be a risk to the public.
Often the Crown introduces occurrence reports if there have been charges laid but no conviction entered, and the Crown can have an officer testify about these reports to say there's been a pattern of behaviour.
