There certainly should be an inquiry, and on much more than Justice Camp's behavior. 

This article says that Justice Camp's lawyer contends in a written submission to the Canadian Judicial Council that “Criminal court judges commonly fail to understand ‘core’ aspects of their job, such as the burden of proof, the presumption of innocence and the need to apply equal scrutiny to Crown and defence evidence ... These ‘core failings’ could be characterized as antipathy and disdain for the … presumption of innocence and by parity of reasoning, those judges could be removed from the bench on the basis of animus. Yet most are not subject to discipline, let alone removal. Their errors are dealt with on appeal.”

If anywhere near true then the Canadian justice system has some serious problems and the impact on public confidence in the system needs to be addressed.
