How many vacancies are there? How many of the new residents are joining an existing household, and how many are family groups that will share a house?

The numbers you've cited don't sound completely out of line. The counterpoint is that housing prices have increased so dramatically.

I don't see it mentioned, but I assume wealthy people without price sensitivity around the world are purchasing extra properties in Canada as climate refuges in a relatively stable democracy, and using AirBNB to generate income from them while they are not needed.

Yes, this has been happening exactly. Although some foreign investors are also just speculating without running an Airbnb. Recent taxation introduced on unoccupied housing has combatted this somewhat, but it's still a problem. But it's also worth noting that this only accounts for a small portion of the housing stock, probably dwarfed by Canadian nationals or corporations buying multiple properties and using them to run Airbnbs, or real estate companies buying property and keeping it unoccupied while it's on market.

I do think the "foreign investor" complaint is exaggerated as a root cause of our systemic housing issues (likely because people find it easier to point the finger abroad), though it is still a contributing factor.
