15% of Canadian homeowners own multiple properties

Some perhaps rather surprising statistics have just come out of the Canadian Housing Statistics Program. Apparently, 15% of Canadian homeowners own multiple properties, representing about 30% of Canada's housing stock.

For example, 15.5% of individual homeowners owned 31.1% of all residential properties in Ontario in 2019 (not sure why 2019 would be the latest statistics available). In BC, these figures are 15% and 29.1%; in New Brunswick, they are 19.6% and 38.7%; in Nova Scotia, 21.6% and 40.9%. In each case, these people owned an average of 2 houses.

Now, we consider ourselves reasonably well off, but WE don't own two houses. So, who are these people? It is not clear how many of them are international speculative investors, how many are locals with a holiday cottage, etc. But it is quite a striking statistic, I thought.
