I would imagine that a lot of foreign-owned property in Canada is owned by foreigners that already have obtained permanent residency, or who are using relatives who have obtained permanent residency. Consequently, they may be treated no differently than any other Canadian. So, would simply “taxing foreigners” really be an effective solution?
