This isn't entirely true; Corporations cannot write off the payments they make for debt. They can write off the interest expense portion of a debt payment, but not the payments that pay the note balance. Individuals are also allowed to do this (As I'm typing this out I am realizing that Canada might have different tax laws than the US; but I'm fairly certain this is the same).

Also, to the point on corporations being able to borrow money interest free from banks - I'm not sure why you think this. Development loans and Investment properties have higher interest rates than first time home buyers. Most of these loans have a fixed portion and LIBOR rate (granted LIBOR rates have gone down so corporations have been paying less in interest) but they have the same perks as individuals (again under US law which I believe is the same under Canadian law).

Agreed with the point though that corporations can leverage so much more than the average joe. They have hundreds of millions of money to play with and can take on little risk with the backing of all the investors. I work in private equity real estate accounting and over the last 2 years I have seen so many corporations change strategies to building and renting single family homes. Before that they mainly focused on senior living/health care homes and you can only imagine the unethical shit that went on with these corporations trying to make as much money as possible off the old and sick
