Two weeks from today, Taylor Swift will land in Toronto for the first of six shows in the city on the Eras Tour's Canadian leg. In December she'll play three more shows in Vancouver. And when the Eras Tour comes to a city, it makes its presence felt in the form of hundreds of millions of dollars, tens of thousands of fans, security challenges, snarled traffic, price gouging and more. So what happens when Swift lands in Canada? What should we expect? And exactly how did a teenage country singer out of Nashville become, quite literally, bigger than the Beatles? How did Taylor Swift take over the entire music industry? And will she ever give it back?
