I hate to invoke HN guidelines, but this accusation violates "Assume good faith".
Here's another source, this time from the National Review:
Remarkably, pre-Hitler Germany had laws very much like the Canadian anti-hate law. Moreover, those laws were enforced with some vigour. During the 15 years before Hitler came to power, there were more than 200 prosecutions based on anti-Semitic speech. And, in the opinion of the leading Jewish organization of that era, no more than 10 per cent of the cases were mishandled by the authorities. As subsequent history so painfully testifies, this type of legislation proved ineffectual on the one occasion when there was a real argument for it.

So now you have both the Atlantic and the National Review claiming this. Are they both mistaken? Lying?
