For anyone interested in a more balanced view, Michael Geist is law professor, research chair, and overall internet policy nerd. I highly recommend his review of the bill: https://www.michaelgeist.ca/2023/04/billc11end/
It's also interesting to put what the Trudeau Liberals are doing in perspective. This is just one of three internet censorship bills that they will pass before 2026.
C-11 (this bill), will allow the Liberals to dictate what platforms show. Simply put, the books aren't being censored, they're just telling the book stores what should be on the shelves. It also adds what is effectively a new tax for content creators which the Federal government will distribute for Canadian content. Keep an eye for scandals about how these funds were distributed in a couple of years.
C-18 is the next one. In short, the Trudeau Liberals will implement another a tax on links, so aggregators such as Google may be forced to pay when they link to say the CBC. Google has already said they may simply stop linking to news services in Canada if they pass this, giving the government funded Canadian news agencies even more power.

The Online Safety Bill - not yet formally proposed - will likely be the coup de gras. Not much is known yet, but given how easily you can censor anything under the guise of "safety" and the Liberal's proclivity towards extra-judicial action, it probably won't be good.
Overall, Canada's internet will look very North Korean by the time the next elections roll about. If you're visiting, you should probably have a VPN ready to go before you cross the border.
