I love this Camp location! It's downtown, next to the huge Eaton Centre Mall, and has a labyrinth right next door.
There are two airport options: Billy Bishop (used for regional airline service) and the larger Toronto Pearson Airport (YYZ). If flying into Pearson, you might want to try using the UP Express train to get downtown. It's just a 25 minute ride to Union Station and then a quick Uber ride to the hotel. Faster and cheaper than taking a taxi. If you're in the US and you pay for your roundtrip UP ticket before you go, you'll get the favorable exchange rate. Round trip is $24.70 (even cheaper if you're 65+).
