If a country that is more capitalist and copyright mad then we are has no issue providing postal data, that our crown corporation has their panties in a twist is a cruel joke. Just adds another reason why I'd never use Canada Post for anything anyways.
Of course, it might not be the case that Canada Post data is under Crown Copyright, since it's a Crown corporation and not a government department. IANAL.
I have made no agreements with Canada Post to distribute my address, the right has only been assumed on my part. It could turn out to be a dangerous liability for all Canadians if it holds up.
The usual suspects in these cases are recipes, Geodata and my personal favourite - Premier League Football fixtures. The latter is in the final stages of a European court challenge that is rightly claiming licensing such a simple set of data for thousands of pounds is absurd: http://www.bbc.co.uk/news/business-17218968
But the CIPPIC is acting as counsel for these guys. They know what they are doing and are the closest I can see.

It depends.
In some places you can copyright a database of facts. In some places you cannot copyright a database of facts. In some places you need to do some 'creative act' to get copyright, some places use a 'sweat of the brow' rule (i.e. that you have expanded some effort, even if it's not creative). It gets coplicated.
I'm not sure. But I'd imagine that books like the Guinness book of world records is probably under copyright and its' just a collection of facts.
