I'm giving the airport rocket the five star boost. I've thought long and hard about this, and it really deserves it. In the advent of the Union Pearson train, a train that is going to cost significantly more than public transport, I want to tout this bus!
It never takes more than 45 from first subway stop to the airport, and as far as cities go, that's fantastic. And it's $3 not, like, $20. The TTC, that's for me!
