Due to slow orders while they figure out the bearing issue. It was much faster before, with an average speed of about 50 km/h. You may have visited just before they returned the Lees-uOttawa stretch back to full speed, which is 80 km/h.
The system is currently shut down while they fix some infrastructure issues (guard rails) and they've decided to redesign the wheel assembly, which will take about 18 months. We're getting there.
Yes, something like the REM would have been better, but what we have, when it works at full speeds, is not bad at all.

REM hits a bit of a sweet spot where they were able to utilize some existing corridors and tie them together with relatively little (big emphasis on relative, it’s a huge project) work. It’s the type of project more places should be exploring - not so much in the tech or anything but identifying those opportunities to tie things together. The Ontario line seems to be following some of these principles.

Ottawa as well. We don't have a whole lot of elevated sections (Bayview, Hurdman, a few flyovers along Stage 2), but we have quite a few trenches, most of the tunneling is cut-and-cover, surface where possible, while still maintaining that grade separation. Stage 3, if ever built (looks doubtful) will have far more elevated sections.
In hindsight though, using the very curvy east end of the Transitway was probably a mistake. I don't think our politicians were truthful when they said it was built with conversion in mind. It's by far the most problematic stretch. Luckily, Stage 2 has far few curves.
I think Toronto has figured it out for the most part with Ontario Line, but Toronto has a history of tunneling and overbuilding where it wasn't necessary, like the Vaughn extension, or Crosstown (much of it could probably have been elevated).
