I thought the 15,000ish number for Toronto is for homeless people, not the sleeping rough. There's 10,000 beds in the Toronto shelter system.
Correct, 10,700 shelter beds, fully occupied most nights, estimates for those who are homeless and un-sheltered range from 3-5,000 on most nights
The total who are sleeping rough in Toronto must be similar.
Probably, but difficult to assess the overall problem comparably, keeping in mind many homeless shelter in transit during the day, regardless of where they stay at night.
I tried digging up Shelter numbers in Paris, and what I get is this.......
- National numbers-
France 185,000 in shelters, no regional breakdown.
Of those 100,000 are asylum seekers in 'refugee' housing.

There are ~271,000 Rent-Geared-to-Income housing units in Paris, which is ~23% of all housing. This would be for the City of Paris (not Ile de France) As the City has about 2,000,000 units of housing
There are 60,000 total units under TCHC or similar, but some of these are market units, its estimated that 41,000 households are currently in RGI housing of some type, in Toronto. Toronto has about 1.16 million units of housing total in the City.
So even the gross number is maybe 6%
Apple to Apples can be quite a challenge.

Likewise, compare Toronto's 'dirtiest' station to a median Paris station unfavourably, but you could do the reverse as well. Trying to quantify the median is a bit harder.
