"Unenforced"? No, no -- the $10,000 fine will be collected. It's just the forced sale that might not occur if the superior courts are busy (and they are!), and if it does occur, the foreign nearly-buyer will be out $10,000. There's no need to encourage baseless Reddit speculation, just read the law itself -- I've linked it, you've linked it -- and reason about how the government will act based on the last 30 years of government (in)action.
Again, I don't agree with your cynicism. But even if you are cynical, consider this: if the government appears soft on real estate prices, they will lose the next election (which may be as early as this spring) to Pierre Poilievre.
...that's a really good point, actually. I am in fact so cynical that in light of this point, I think I'm going to go around loudly praising this bold new law from the wise Liberals.
