This year, Medicine Hat became the first city in Canada to effectively end homelessness. Almost 900 people in this small town of 61,000 have been placed in rent-free apartments or houses. And the benefits are clear: police calls and hospital emergency room visits are down. "You're going to end homelessness? Yeah ok, good one," he recalls thinking. But the society argued that the $20,000 per year cost of housing someone was as much as four times less than the expense of policing and health care when that person lived on the streets.
