You may recall Khaleel Seivwright, who during the pandemic built tiny homes for Toronto's unhoused. He was charged by the city and forced to cease construction. The city claimed it was their land and the structures were fire hazards.
Inspired by Seivwright, Ryan Donais is constructing Tiny Tiny Homes to solve the same issue. He's incorporated smoke detectors and put the structures on three wheels, therefore qualifying as bicycles under Toronto law.
You can get involved or donate to Tiny Tiny Homes on their website.
