I'm not smart enough regarding macroeconomics to know the right answer, but I feel like there has to be a solution that makes home ownership affordable for new entrants into the market without causing the value of existing homes to tank so hard and fast that we end up with a 2008-style crash again. I'm pretty confident that getting large-scale corporate investment out of the picture is part of the solution, and I don't care if the method involved there hurts the corpos pretty bad. Maybe an oppressive rent-control scheme that makes keeping the properties untenable for corporate owners, forcing them to want to sell as fast (and therefore as cheaply) as they can. I don't know what zoning laws are like in Canada (compared to here in the US), but I think merging zoning for low- and mid-density residential such that suburban NIMBYs can't block multi-family units from being build is another necessary step. As far as everyday folks who bought into the housing system, I'd like to see them as protected from the fallout as possible, especially since (at least the US) government has been all-too-happy to let home ownership replace pensions as the primary way people are "supposed" to retire.
