The time seemed right for the City of Ottawa in spring 2007 to take a chance on a new bus finally available for the North American transit market.
City higher-ups, who are no longer with the corporation today, told council back then that the double-decker buses could offer a better transit experience for customers and could even help increase OC Transpo’s ridership.
This was the start of Transpo’s buy-in to double-decker buses.
(...)Transpo liked the buses because they suited Ottawa’s vast coverage area for public transit. Plus, the fuel consumption was better than the articulated buses, which could deliver budget savings and help the city’s efforts to help the environment.
