In Erica's flashback to 2001, a logo belonging to the store "Winners" can be seen in the background as she walks on the street. That logo is the one used by the store from 2009 onward.
While Erica is talking to Dr. Tom (who is dressed as a mime), a partial sign can be viewed of Winner's, a Toronto chain clothing store. Although this episode is set in 2001, the Winner's location shown (41 Front St. E., Toronto) didn't open until Fall 2007.
