The intent of the policy recommendation is not to solve everything, but to solve this problem that has emerged, which is an investor class that is not currently disincentivized through taxation. I would recommend excluding principal residences for that reason, because they are our homes, as opposed to homes that have been acquired for the purposes of generating revenue.
The specifics of how that taxation takes place is not something that I've gone into detail.... What I wanted to highlight is that, currently, there is a tax incentive to be an owner of investor units and housing that could be mitigated through creating more tax fairness. That tax fairness would involve taxing the capital gains on investor units.
