If taking money from stupid people is harm, then few business could survive that scrutiny.
Completely true, but medicine is considered a special case because the conseqeuences are such that often a victim cannot seek justice (he's dead). There exists a method for vetting medical claims prior to watching millions of trusting customers die. In Canada, it's Health Canada's approval system, and it has analogues elsewhere, such as the FDA in the US and the NHS' approval system in the UK.
Trudeau is peddling conspiracy theories, which is completely legal. Where he crosses the line is in overselling the product's value proposition. People think the book contains a list of cures.
The setup in this case is four-tiered, but not very inventive:
Step 1: informercial that says there are cheap, reliable, safe alternative treatments for many illnesses, but they're suppressed by a collusive scheme involving Big Pharma/Government/Media/Medicine, and if you want to learn more, buy the book. Incidentally, stop taking any drugs, because it is a scientific fact that none of them work, and all of them are harmful.
Step 2: the book says there are cheap, reliable, safe alternative treatments for many illnesses, but they're suppressed by a collusive scheme involving Big Pharma/Government/Media/Medicine, and if you want to learn more, go to his website. Incidentally, stop taking any drugs, because it is a scientific fact that none of them work, and all of them are harmful.
Step 3: the website says there are cheap, reliable, safe alternative treatments for many illnesses, but they're suppressed by a collusive scheme involving Big Pharma/Government/Media/Medicine, and if you want to learn more, pay $9.95/mo for a subscription to his newsletter. Incidentally, stop taking any drugs, because it is a scientific fact that none of them work, and all of them are harmful.
Step 4: the newsletter says there are cheap, reliable, safe alternative treatments for many illnesses, but they're suppressed by a collusive scheme involving Big Pharma/Government/Media/Medicine, but it would be illegal for him to give medical advice because of they way the conspiracy has corrupted the legal system and denied him his first amendment rights.

This is a mundane scam, but run by an expert with years of experience and an established apparatus. Each level squeezes more money out of the mark. The fact that he doesn't specify any treatments is actually some protection from redress. The fact that each handoff is to learn "more", not to learn "what these treatments are, specifically" is also strategically worded to hamper allegations of not providing what was advertised. He's trying to operate within the letter of the law by selling opinion by calling it medical advice.
