Just lurking here but have persisting impression that all
buildings fall to the right.

You might note that the shoreline is level, and the buildings are
vertical. Just because the Vancouver city planers located shorter
buildings to the right, doesn't actually mean they are falling to
the right.

Check for yourself, the verticals are vertical, and the horizon is
level;

It's easy to hide a lean when not zoomed in, where a 1 pixel line easily
covers several pixels of image data.

Here you can see that it's leaning:

Yep, and I reckon the problems stems from using the perceived
waterline as a horizon to level it. The view point is above the level
of the horizon and the waterline is at a considerably varying distance
from the camera. Setting it up on the building verticals in the middle
of the image would have been more accurate.

OK!
This time I ignore the waterline and just checked verticals across the
the buildings.

So here I believe I have the verticals perpendicular;

Just lurking here but have persisting impression that all buildings fall
to the right.

Yeah, I see it too. Nothing to do with the height of the buildings.
Actually, the buildings are leaning. I guess the image is a little
rotated to keep the shoreline level when in fact it is receding away on
the right side.

Yup! It is not a linear shoreline. It falls away tp the right, and
there are several jetties and the shadows they cast, which add to a
broken shoreline.

In Savageduck's image with the vertical lines drawn you can see on the
second building from the left that the building edge is not parallel to
the guideline.

Sometimes there are compromises to be made. The distortion on the right
is minimal, any further correction there would result in gross vertical
distortion to the buildings on the left and center. That would have
been far more of an issue.

As I said sometimes there are composition problems involving line and
distortion imparted by a particular lens. In the case of the example
below there were multiple issues ranging from exposure, to conspicuous
non-vertical, non-horizontal, & non-parallel lines. So there was much
tweaking involved to reach a reasonably acceptable image.

Much better!

Rule of thumb - if there are buildings, especially tall ones, in the
image, level vertically on them. If not, level on horizon. If drunk, level
on nearest horse/dog/sand castle.

I think your first approach was better. For some reason the buildings
in the center look like they're leaning to the right now.

I think a more fruitful approach would be to get the center aligned
exactly vertically and then use perspective crop to straighten up the
buildings on the left and right edges.

Depends on how far away those buildings are. If close, the vertical
lines would be angled.
