Light rail would still stop at road crossings, and it would stop at many stations along the way.
Light rail would not stop at any road crossings if said light rail was above or below grade. If it's at-grade there's no point whatsoever in bothering with it; it'd be just as bad as a bus.
And how many stations would, say, a town-to-Swartz Bay line have? Swartz Bay terminus, Sidney, the airport (ideally!), Saanichton, Keating, Royal Oak, Uptown, Hillside Ave, in-town terminus*.
* - the in-town termunis would probably be somewhere near the arena, as that's where the Blanshard median ends and for the bits south of Uptown running it along that median seems to make the most sense.
