Common sense tells us that one of the most fundamental human rights, regardless of where it might be codified in various UN declarations etc., is the right to housing.
I'm thinking about this question because in the past week at least two human beings have frozen to death on the streets of Toronto, one of the richest cities in one of the richest countries in the world. A country that prides itself on its record of do-gooderism all over the planet. Check out the Dept. of Foreign Affairs website and you'll be bursting with pride at how Canada leads the world in saving the lives of the less fortunate.
But in Toronto we let our own freeze to death in the street.
