OTTAWA — The air was sucked out of the bizarrely freezing-cold Canada Room at the Rogers Convention Centre in downtown Ottawa at 10:07 p.m. local time, when CTV News made its call for a Liberal government. A relatively rowdy crowd near the stage, surrounded by photographers and cameras, had been leading chants of “bring it home!” as positive Conservative results trickled in from Atlantic Canada. Things quickly ran out of steam once results started coming in from Quebec and Ontario.
