Demand in Canada in entirely from immigration, there's an obvious solution.

Ah, so is this tied to your previous comment? Ie you're saying ~"not a supply issue, it's a demand issue" and you mean that there is an artificial demand causing the supply to be insufficient. That the supply would be otherwise sufficient, if not for the external sources of demand.

I'm not familiar with the immigration issue in Canada, i'll have to peek at that. Appreciate your clarity
