Quebec City rolled out a $3-billion tram project for the province’s capital city.
Quebec City Mayor Regis Labeaume made the announcement Friday alongside Quebec Premier Philippe Couillard.
The 23-kilometre tram line would travel through the city mainly from west to east and would be complemented by a 17-kilometre ‘tram-bus’ line, complete with electric tram-buses and a reserved bus lane.

Is this tramway entirely on off-street track?

I don't know about entirely but they are selling it as right of way with intersections at grade as opposed to fully separated https://www.youtube.com/watch?v=3PKtfiIzmFg" onclick="window.open(this.href);return false;

According to an animation I have seen, this tramway will be partly underground. Had any of the previous tramways in the same city run underground in these locations, then Quebec city would still have uninterrupted tram service on these lines today!
