Collecting information on citizenship, ownership, etc will NOT change anything. 

RESTRICT land and real estate ownership to Canadian citizens and landed immigrants.  

There is NO point in building more houses for speculators, foreign investors and money launderers while Ontario pretends it is 'taking action'.  STOP all political cash-for-access fund-raisers where the guest list includes non-Canadian millionaires & billionaires who obviously get too much "face time" with spineless Canadian politicians who only think about their party stripes. Why take money from people who cannot vote in Canada?
