Those Kingston shots are really the only angle by which the city's skyline appears significant--the row of modern high rise hotels along the waterfront at the eastern edge of the core being the only high rise cluster we really have (other than 1960s-1970s era suburban rental towers which are actually insanely common given how small the city is).
High rises, including some office ones, are going to eventually emerge in the north fringe of the downtown core. The zoning and infrastructure is falling into place, market demand just needs to follow (so, another 50 years

). There's also some permissive high rise zoning at the western gateway to downtown (which there's already a pair of 10 floor twins taking advantage of). Eventually, the city will have a U-shape skyline surrounding downtown to the north, east, and west, while downtown itself and its southern flank remain heritage-protected low & mid rise.
Some would say that it will downtown feel like some sort of uncomfortable canyon. Personally, I don't. While the waterfront hotels largely block views of the water from most of downtown, that actually improves downtown IMO. Makes the streetscapes feel more enclosed.
