The numbers didn’t add up for Graham Henderson. Toronto had four million people and a music economy of $500 million a year. Austin, Texas had a fifth of the people, 800,000, and three times the music economy, $1.5 billion a year. As president of Music Canada at the time, Henderson set out to figure out the math and make Toronto make more music money. Today, live music venues in Toronto alone generate a total economic impact of $850 million annually, according to the city’s music office.
