Keep Commercial real estate totally market driven but ensure people do not hoard residential real estate.
1. Limit profiting from residential real estate. Any residential real estate that is not the primary residence of a person (as indicated by over 10-20 years of address given in income tax returns) should attract high tax upon sale. It should be responsibility of buyer / buyer agent (realtor) to with-hold that tax and remit to the government. So long buying and selling houses are not terrible profitable, people will not financialize them like they do. Those who stay in their house for long time and use its appriciation to cashout during old age will still be able to do so.
2. Limit foreign access to housing market. Should be obvious... need 3-4 years of tax return and PR in canada to buy houses here. Otherwise pay 70-80% tax.
3. Release more land from crown land to built purpose built rental properties, make eviction and rental laws stronger for rental real estate.
4. If nothing just release more and more land to build new sub-urbs and towns around economic centres. Build more transit facilities.
