As Canada looks to update its copyright laws as part of the USMCA, the replacement for NAFTA strong-armed into existence by Donald Trump, we covered previously how ridiculous it is that copyright interests have been allowed to stick their nose in the whole thing and make all kinds of demands. Part of USMCA involves allowing Canada to keep its notice and notice system, as opposed to the notice and takedown system we have here in the States. While Canada's system is preferable to our own, it's not without it's flaws, of course. One of those flaws is how the notice and notice system has devolved into a deluge of settlement letters.

So dire is the plague of threat letters, in fact, that ISPs in Canada are using this opportunity to suggest outlawing those threat letters be included in the updates of Canadian copyright laws.
