What to wear
We highly recommend signing up for Uber if you haven't already. We suspect it'll be the easiest way to get to and from the venue, though streetcar and taxis will also work. Note you cannot take Uber from the airport when you arrive, but you are able to take it to the airport when you're leaving.
The TTC runs the subways, streetcars and buses in Toronto. Transit makes for an easy and economical way to get around downtown and beyond. You can pay with cash, get yourself a prepaid Presto card, buy weekly or even daily passes (2-for-1 on weekends).
The UP Express is a train that runs between the airport to downtown. For those of you staying a short walk from Union Station, this could be an easy and cheap option at $9-$12 depending on how you're paying (it's cheaper if you have a Presto card).
