The long-awaited city council vote on changing Montreal's Parc Avenue has been postponed until midday Tuesday.

The vote — which was supposed to take place during a regular Montreal city council meeting Monday night — was pushed back because of a seemingly unending stream of questions from members of the public, who showed up in huge numbers at city hall.

City council threw in the towel around 11 p.m. Monday night, after hours of debate and questions over the idea of renaming Parc Avenue after the late former Quebec premier Robert Bourassa.

The delay angered several residents who have fought the proposal for more than a month.

"I'm so mad. I'm so mad, and I don't think I'm the only one," said Alison Louder, 22, who has helped bring together a coalition of residents and business owners opposed to the renaming.

"I think the process is ridiculous. I mean, to make people wait until 11:30 at night, and then not even vote on it? What the hell is that?"

Many merchants along the street, such as Chris Karidogiannis, said they're eagerly waiting the vote results to be able to plot their next step.

"You cannot feel that people don't have a voice. You cannot treat them with neglect and contempt, which is what's been happening here," he said Monday night, adding that the coalition will consider taking legal action if the city approves the proposal.

City councillors have been instructed by mayor Gérald Tremblay to vote freely on the motion, but it's still unclear how much opposition there actually is to the name change within council.

The vote is expected to take place at noon on Tuesday.
