It's an airport link. Airport trips are generally planned affairs.
People coming into town are likely willing to wait an average of 7.5 minutes for an express train to get downtown and it's on par with other airport links in other major cities. Tokyo's Sky Access express
Line runs about every 20 minutes
(though there are multiple other cheaper longer options)
People going to the airport usually have slack time built into their schedule or they plan their trip. Flights are on fixed schedules.
The 192 bus in Toronto leaves approximately every 15 minutes.
Even the subways in Toronto run at about 6 minutes frequencies, don't they?
We have to remember that the Toronto Airport Link will be a premium
express service, so bus service will likely continue to the airport. There will be multiple options to get into the city.
I'm glad they're not just doing something like extending the subway to the airport because that would end up being a long ride without much room for improvement. It would suck money away from more valuable projects. This premium express will likely pay for itself and maybe even turn a profit.
Vancouver doesn't have much in the way of alternative ways to get downtown because its airport is close enough to roll the two services into one higher capacity urban train line.
