CBC is grasping at straws trying to put the blame on Facebook for the very bill they pushed through, that had very predictable consequences. Canadians news publishers have no one to blame for this but themselves.
The article basically reads as though they're upset for not being paid by Meta during emergencies and sad they can't profit as much off people glued to watching emergencies (it's absolutely not because they're truly concerned for the actual ppl facing the emergency). It's quite tasteless for them to pull the misinformation card when news publishers aren't always known to spread accurate or helpful information -- they're mostly there for the fear mongering. And Meta's response on that front is the correct one: they're not blocking government sites and government sites should be considered the sources of truth and information during emergencies.
That said, unrelated to news link sharing, there's a larger discussion to be had around emergency broadcasts over the internet: should the government create legislation to have an emergency notification tool in place that can be triggered on Canadian websites and websites catering to Canadians (social media included)? Many institutions, including universities, have their own systems for doing exactly this so why can't the government?
There's only one country with even a remotely similar legislation, that being Australia. Facebook got the amendments it wanted before the Australian Code received royal assent.
If you're going to cry foul about how Facebook is following the legislation Canada is putting in place, you'll need to try harder than that.
