This is an architecturally gorgeous space, that has excellent WiFi and plenty of electrical plugs for personal electronics. Since this is a district library, it has consistent hours and is open on Sundays during the school-year. It has a great meeting space, and has a decent audio/visual collection.
Since it is on the Bloor-Danforth TTC subway line, I get off at Dufferin and walk the one block it takes to get to Bloor-Gladstone. When I am not using TPL's Reference Library, or the University of Toronto's Robarts Library, this is where I go to read, write and relax with a book or digital media, or watch the street-life unfold below me.
