I don't think Toronto's ever had more than 2 shows. Plus, they're getting the opening shows of the leg. That's good enough, thank you. There's a ten day gap after the Montreal date, which, btw, is a Saturday night (meaning a giant PARTY!!!) and when the first show sells out in 3 minutes, they'll add another. That's what they did on Elevation and I'm confident they'll do the same this time.
I doubt this is the complete set of dates. There are large gaps in the schedule. More shows will be added. I will be very surprised if U2 does not add at least 1 Alberta date and at least 1 more Montreal date. If they add another Toronto date before those, I won't be a happy customer.
