Yes. There was a companion case that was also dealt with in 2004 by the Supreme Court of Canada. They indicated, as you quite correctly pointed out, that there would be a presumption that this will be held in open court.
That being said, as sometimes happens in other aspects of our criminal law in this country, where it has become necessary and reasonable.... You cited the example of, for instance, the protection and the safety of a witness; the courts will take that into consideration.
The presumption of an open hearing has been part of the laws of this country for centuries. This bill is consistent with that presumption, as indeed all our legislation is. That said, we have a responsibility to protect those individuals who do come before the court, and therefore that additional power is given to the court.
