The waypoints are at setpdown fix locations, with at/abv designators, which appears to add a quasi vnav to the RNAV approach.

But I still don't believe the AR necessarily means that GPS is required. You certainly don't need GPS to fly a procedure with waypoints in all cases.
As the FAA document
Special Area Navigation Visual Flight Procedures you cited in your previous post says:
RNAV Equipment Requirements and Procedure Flyability. Only RNAV systems compliant with AC 90-100, using distance measuring equipment (DME)/DME/Inertial Reference Unit (IRU) and/or global positioning system (GPS) sensor inputs, are acceptable for use on an RVFP.
After the release of the YHZ accident report, Air Canada has committed to upgrading their narrowbody fleet with GPS by the end of this year but there is a good chance that C-FKCK had not yet been upgraded. If didn't have GPS it might have made a difference in matching the picture on the screen with the view out the window when they were lining up on final.

Interesting, when you listen (to the recording in post #4 of this thread) you hear different requests coming in.
at 1430 you have a delta request 28R visual;
at 1705 someone requests FMS 28R, bridge visual;
at 1942, a delta asks for RNAV bridge visual 28R;
at 2110, you have air canada 759 request FMS bridge visual 28R.
You might want to listen to that recording again.
I don't think any of these folks are
requesting the FMS Bridge Visual 28R from the
tower controller on the link posted by that smart feller in post #4. They are reporting their assigned approach procedure to the tower. You probably do that when you switch to tower, don't you?
They were already
cleared for that approach by the previous controller.
As I posted earlier:

Thinking about your comment, perhaps Air Canada wasn't authorized the FMS Visual. If so, seems like they would have been flying the plain vanilla Quiet Bridge 28R Visual.

Yep, I agree, their clearance for the
FMS Bridge Visual RWY 28R is in the approach control clip linked again above. And there still is no runway 28C...
