Canada law is weird. They have "Crown copyright"

I don't know about Canada, but the UK has 'crown copyright', and it's essentially the same as regular copyright, but the copyright is owned by the government. Places without a crown still have governments that have copyright.

There some weird things, The King James Bible, the Book of Common Prayer, and the Peter Pan stories are under perpetual unending copyright. (Well Peter Pan will go public domain when the Great Ormond Street Children's Hospital ceases to exist)

US law mandate that data created by the tax payer money, ie the government, be Public Domain.
