You are paranoid. “You will be taxed on things you did not even know you owned”. Ridiculous.
This was said with tongue in cheek of course. However, it is happening everywhere already. Today: “The B.C. government has proposed a law that would extend the rent freeze to the end of 2021, cap future rent increases to inflation and prevent illegal renovictions.” You say this is not taxation? The city of Vancouver increased its property tax by 26 percent in 4 years, at the same time, you cannot raise your rent…and if you leave it empty you have to pay 5% taxes (that did not exist before 2 years ago). So, maybe I should have said: Homeowner, investor developer, rental purpose home builder, etc., etc.: “You won’t know what you will be taxed as yet…”
