MetrO is good but would scare the no-tax crowd that elects mayors in this town, and is more ambitious than what we're building anyway.
As much as I like MetrO because it might "jolt Ottawa out of its small-town mindset" as Admiral Nelson put it, the Ken Grays of this city would flip out because it sounds ambitious or whatever. Case in point was when the city was considering light-metro (like Vancouver) technology; NYMBYs freaked out.
Name aside, our MetrO beats out Vancouver's Skytrain in capacity anyway.
Ottawa; 120 meter platforms outside the subway (expandable to 150) and 24,000+ phpd
Vancouver; 70 meter platforms and 20,000 phpd
