there is literally nothing people can do. the party in charge has a majority government and a media biased enough to sell this bill as a positive thing.
the only thing that could make a difference is if apple, whatsapp, and instagram all blocked canadians from using those services. the liberal party and the media would still find a way to blame trump for it, and the pm's popularity would increase.
Remember that media bias comes from being state funded media. Of course they're going to massage the narrative towards the party giving them funding.

That is literally what is going to happen if this legislation is allowed to pass. WhatsApp will block Canada, and Apple will remove any impacted service from Canada, like iMessage.
