Canadian Facing Criminal Charges for Downloading Publicly-Accessible Documents

I’m trying to think of a physical-world analogy to this:

Imagine walking into a government office and seeing a table in the lobby with different stacks of documents. Some stacks are labeled and some are not. You can take a copy of each document you’re looking for, and you find it because of the label, but what happens if you take an unlabeled document? Maybe you’re just curious and nobody said you couldn’t look at the other documents. If the documents were that important, surely they wouldn’t just be sitting on this public table.
