Guest: Matt Blackett, "Spacing" magazine founder and creative director  "Spacing," the independent magazine about public space issues in Toronto, turns 20 years old this month — somehow surviving and even thriving in a media landscape that’s been punishing to much more established titles. Founder Matt Blackett joins "This Matters" to talk about how the magazine began and how it has developed unconventional ways to make money and influence people from subway merchandise to the opening of a retail store. Blackett  also talks about why, after everything, he remains optimistic about the city’s future. This episode was produced by Julia De Laurentiis Johnston, Paolo Marques and Ed Keenan.
