Then, all the commercial landlords and condo corporations who seek out banks and large chain retailers for their retail will wonder why fewer people are coming downtown. No one wants to travel 1 to 2 hours downtown in traffic or lousy transit for the likes of a street of retail bank branches, Shoppers Drug Marts, and Winners. They want retail they can't find at home.
There's a place for chains, but they're becoming too prevalent downtown. Also, big international chain restaurants will draw people once due to hype. Many of those people will never return due to the generic nature of standardized franchise restaurant food, no matter what country it's from.
