"In 2014, the B.C. Legislature issued an apology for the multitude of discriminatory laws and policies imposed on people of Chinese descent from 1871 to 1947."

I see a problem to this protectionist tax. International trade agreements have precedent over sovereign laws. Discriminating taxes on foreign investments could be declared illegal by treaties such as NAFTA.
Most international trade treaties are to empower global corporatism and allow their tentacles to penetrate any protectionist tariffs. 
Mr. Bond, Please look more into whether Canada could be successful in cooling their foreign fueled housing bubble with a NDP tax.
