>In the City of Vancouver’s 2019 homeless count, based on those who responded, 16% (156 people) of the homeless reported they were from an area elsewhere in Metro Vancouver, while 31% (299 people) were from another area of BC, and 44% (435 people) from another area of Canada.
Where is the data backing up your claim?
If you scroll down slightly (3.11) you'll see 81% of respondents had a home in Vancouver before they became homeless, which is the data to match the claim ("overwhelmingly people who had stable living situations in those comfortable locations, and became homeless there").

If you become homeless after 6 months of moving, you weren't financially stable to begin with.
EDIT: It's a moot point anymore. The fact is, they are in Vancouver and are homeless. We should help them regardless of where they came from.
This might shock you, but the majority of people right now are not financially stable.
Where are you getting this from?
