Sounds like they are attacking the US based stores along those streets.

Michael Hyatt, who was at a Yonge and Dundas gym, said the protesters seemed to target a number of U.S.-based chains.
“It is pretty horrible what they have done to a lot of the stores here. They’ve destroyed the windows at an American Apparel — they destroyed all the windows and pulled out the mannequins and [threw] feces into the store.
“It stinks and it is unbelievable. Foot Locker is destroyed. Pizza Pizza is destroyed. They’ve kind of gone up the street and picked at every U.S. vendor they could find. It’s really kind of sad.”
