According to the interweb this year the programme book pick up and lottery drop off will be at the new box office at Toronto Life Square. The office has not been set up yet, but it may be on Level 3. That level has the main food court and lots of tables so you can start your selection process right away.
There’s a gelateria downstairs as well, but I don’t want to include the food in the same post as the picture of that bathroom. Don’t forget to pack your sanitizer.
