For testimonials from some of the people living in these Toronto tiny shelters:

Some interesting notes about the shelters from the video:

- they are on wheels, and because they're off the ground they stay warm and dry even when it's raining

- they can be locked from the outside or inside, which gives people a sense of safety (e.g. people's tents can get slashed up, but these are strong), and they can also safely leave possessions there

- they let people sleep much better (longer, more comfortable)

The amount having these things improves a person's psychological state is immense.
