When it comes to high floor buses , for the same 40ft length, they held more people compared to the low floor buses. And I'm pretty sure the Ontario government made some legislation for transit systems to order only low floor buses.
TTC has unique spec as do mNy transit systems, and as mentioned before, NYC has way harder roads and demand. So if a bus can survive NYC, then surely they can survive Toronto.
One thing is for sure, TTC has never really like artics.
Personally the nova buses are the worst rides I've experienced since TTC has went low floor. With a shorter wheel base, it helps with tight turns, but a rough ride.
But with a recent stop order on the NFI buses, that was also recently lifted in Dec, it could potentially hurt NFI chances in Toronto. Hopefully NFI can redeem themselves.
I recall hearing a rumor years ago that NFI wanted to sue David Gunn or TTC over remarks about their buses. But with NFI being the last bus purchase under David Gunn, I highly doubt that.
One thing I found interesting was the RTS buses TTC got in the 1998 was built in New Mexico, despite Orion being made in Ontario and Nova actually having a plant in Quebec. Not sure how TTC got around that.
