The Alstom rolling stock is apparently going to be a new variant of the Citadis, to be known as the Citadis Spirit:

"The new Citadis Spirit that Alstom is launching in the North American market will have many features that accommodate Ottawa’s particular needs. Designed in a high capacity version, it will be able to operate in extreme winter conditions. It will also benefit from a top speed of 100 km/hour (65 mph), reducing travel time between suburban areas and the City Center. As all Alstom trams, it will have a full low-floor accessibility and onboard bicycle storage. Alstom will build the vehicles in America and assemble them in Ottawa."
