Why would you? Tax is a very effective mechanism to control economy. And don&#x27;t have to think on extremes even! Very wealthy people are buying condos there just because it&#x27;s the best (passive) investment for their cash. If you increase tax for vacant property it will incentivize selling over time,or at least renting.. more offer with less cost.<p>In a macro economical sense Canada already profited from getting foreign $ invested in buying those properties anyway, time to make Vancouver livable.
