It's both.
Agreed. I have only found the taxiing to be annoying when in the area. While at Ireland Park, the take offs and landings were alright,
Doesn't look like that to me.
UPX Opening in 2015, YTZ ridership:
2015 - 2,503,118
2017 - 2,803,156
2018 - 2,807,208 All-time peak ridership
2019 - 2,774,000
2024 - ~2.2 million - which isn't bad considering the drop in flying to the US
No one from the CBD or current YTZ passengers would go to Hamilton. Much too inconvenient. Although Canada should probably beef up Hamilton anyway.
45% of passengers use a car/taxi to get to the airport which means that 55% of 2.2 million is hauling luggage (for 2024).
There is also the direct 2000 operational jobs related to the airport.
"In 2024, Toronto’s ferry service carried more than 1.4 million passengers. In 2023, that number was approximately 1.5 million passengers." It is estimated that including private taxis you have 2 million passengers to the islands. It is estimated that about 750K of that is tourists.
As stated, I don't feel Harbourfront is negatively impacted by the airport. The planes don't impact our experience there. As far as noise, that affects only those closest to the airport. I visited my friend often who lived in the condo right across from Norway park and his balcony faced the airport and it never impacted us and the only discussion about the airport was convenient it was.
While I do love the islands, the value of the islands is being hugely overstated in this thread. Most people don't know Hanlon's or Ward exist and tourists generally go to Centre Island/Centreville - estimated 1.5 million visits annually out of an estimated 2 million visits to the island. I didn't realize that visits are that slanted towards Centreville - 75% (official info says up to 80%)!!!! The argument is actually Centreville vs an expanded airport! Do we all think an expanded airport makes the Centreville experience worse?
I am actually quite surprised as the more research I do, the stronger the case for an expanded airport. For me, the answer gets even clearer: Islands + expanded airport provides the strongest benefits for Toronto.
