Not to mention the funded Hamilton LRT, the proposed Ottawa stage 3 LRT, and the Gatineau and Quebec city trams. All of which are at least in the 4 billion range. Just last week Quebec paused work on their tramway after costs were projected to reach
$8 billion ! ION's cost of $868 million/19 km in 2014 now seems like a bargain. Its probably better to spend that money on purchasing new buses and training additional operators than on any higher order transit. Alas we now risk falling back into the transit expansion stagnation of the 2000s (at least for trams).
