The article is pretty lazy with describing the tax. The municipal government of Vancouver doesn't have any of these taxing powers, and the tax comes from the Provincial government. It only applies to the Metro Vancouver area however, so some are already stating that there has been a spillover effect in other areas of the Province, such as Victoria.
The foreigner tax is provincial (applying only to Metro Van). The vacancy tax is municipal, applying to CoV. The city requested special taxing powers from the province for this tax and received it.
thanks for the reply @Tiktaalik, I couldn't work out if this is a top down or bottom up response. So it's Provincial (State in my country). Interesting.
Which government? Fed, state, municipal?
