A Toronto man's Ticketmaster stub collection shows just how good concert-goers in Canada had it in the early 2000s. The average concert ticket, I'd say, was about $50 to $60, but I'm going with the high end. Tens of thousands of music lovers even signed a petition urging Canada's federal and provincial governments to regulate the resale of concert tickets. Ariana Grande has recently been praised for sparing fans from dynamic pricing, a practice that uses algorithms to determine ticket prices based on demand. What are your thoughts on the change in concert ticket prices over the years?
