Flight
Pearson is the largest airport in the area and will have the most flight options. It’s about 35 minutes from downtown. We’d suggest Ubering or taking the UP Express train from Pearson Airport to Union Station. The train takes about 25 minutes and drops you off right downtown. https://www.torontopearson.com/en/transportation-and-parking/up-express
Flight
Billy Bishop is right downtown and definitely the most convenient but has fewer options and only select airlines.
Hotel
Delta is within walking distance to the reception and is centrally located. It’s a 10 minute walk from Union Station.
House Or Rental
We'd also recommend taking a look at Airbnbs and VRBOs. There are tons of options.
