I know where this building is and without directly giving it away I will help by posting some points about it. I hope this building is significant enough to be a TAG.
This building is both a cruicial part of infastructure and an architecturally acclaimed historic building in Toronto. This palace of purification is a national historic civil engineering site and has been used in three different movies as an asylum/prison, and has been in many TV Series as well.
I hope that helps someone find it, I just hope they can move it to a better location, maybe a Tim Hortons?
