It's a bit of a mixed bag. Not purporting to have reviewed in detail the laws of hundreds of foreign countries, I would say this bill is unique in the degree to which it emphatically now authorizes a judicial officer to allow a Canadian executive agency to violate foreign law.
In other jurisdictions that I have looked at that have foreign intelligence operations, their laws are creatively ambiguous on that point. The reality, as we all know, is that spies spy and in the course of spying they may violate the laws of the countries in which they spy and international law in terms of state sovereignty.
Again, not having exhaustively reviewed all the comparative law, I am not aware of a statute that as emphatically indicates that a court may authorize spying in violation of international and foreign law.
I think also in the text of the document you were referring to earlier, I called it “courageous” at some level that the Parliament of Canada is prepared to put its stamp on a law that emphatically signals that we are prepared to violate the laws of foreign countries, potentially including allies, in conducting foreign surveillance.
That potentially has political implications, and I imagine there are people at the Department of Foreign Affairs who are quite exercised or potentially quite exercised about the potential fallout that this might occasion.
But to answer your question, in my albeit limited experience, this law is fairly unique.
