The public is exhausted by the fact that the line has been in development for years, the affected neighbourhoods had to put up with lengthy periods of construction/road closures (like what the west end is experiencing now), the system has missed multiple deadlines, significant construction deficiencies were revealed, and we still do not have a hard-and-fast date for when to expect the trains to actually enter revenue service. There will be plenty more gallows humour until we can actually board trains on a regular schedule.
Why can't Canadian municipalities do transit projects? Edmonton has an appalling recent history when you consider both the Valley and Metro lines--and the Metro line wasn't a PPP, so there's no TransEd to blame in that case. The situation is every bit as bad with Toronto's Line 5, which again is riddled with deficiencies, is way behind schedule and has no opening date anywhere in sight.
