Louisa St. no longer exists, it used to run parallel to Albert St, just north of it. The Eaton factory was demolished, now the site of the Eaton Centre.
View looking east on Louisa St. to James St., the T. Eaton factory looming in the distance, 1920 (97/163)
I could be mistaken but I seem to recall a Louisa St. titled or named mall entrance off the west side, towards the Bell corporate building and Trinity Church. That may be the last use of the street name.
Very interesting. I did not know that.🤔
Mom used to say the TTC driver called out the street names – Shuter Louisa, Albert next. Always got a giggle!
