Did I get lucky? Lol

So I had a package from Poland coming to Canada, and they left the slip for me to pickup at the Canada post store. I expected to pay duties as this was a bit expensive, but to my surprise they just gave it to me. On the customs sticker it says the value of the item is $850, and it wasn’t marked as a gift so wouldn’t I normally have to pay duties? Nonetheless, I’m happy with that lol
