TORONTO - Canadian lawmakers voted Monday night to extend the emergency powers that police can invoke to quell any potential restart of blockades by those opposed to COVID-19 restrictions.

Lawmakers in the House of Commons voted 185 to 151 to affirm the powers.

Prime Minister Justin Trudeau said earlier that the powers were still needed despite police ending the occupation of the nation’s capital by truckers over the weekend and police ending border blockades before that.

Emergency Preparedness Minister Bill Blair said the protesters were going for the “lifeblood of this nation, which is trade with the United States.”

Trudeau noted there were some truckers just outside Ottawa who might be planning further blockades or occupations. His public safety minister said there was an attempt to block a border crossing in British Columbia over the weekend.

The emergencies act allows authorities to declare certain areas as no-go zones. It also allows police to freeze truckers’ personal and corporate bank accounts and compel tow truck companies to haul away vehicles.

The trucker protest grew until it closed a handful of Canada-U.S. border posts and shut down key parts of the capital for more than three weeks. But all border blockades have now ended and the streets around the Canadian Parliament are quiet.

Ottawa protesters who vowed never to give up are largely gone, chased away by police in riot gear in what was the biggest police operation in the nation’s history.

“The situation is still fragile, the state of emergency is still there,” Trudeau said before the vote.

Opposition New Democratic Party leader Jagmeet Singh’s party supported it, ensuring Trudeau had enough votes. Singh said they know there are protesters waiting in the surrounding areas of Ottawa and in the capital itself.

“They need to be cleared out,” said Singh, who also noted there have been convoys that have been intercepted.

“This is an attack on our democracy. This is a group of folks who are very clearly connected to the extreme right wing, The organizers clearly have a goal in mind to undermine democracy. That’s something we can’t allow to continue.”

The Royal Canadian Mounted Police said those who had their bank accounts frozen were “influencers in the illegal protest in Ottawa, and owners and/or drivers of vehicles who did not want to leave the area.”

Finance Minister Chrystia Freeland said earlier anyone affected has an easy way to have their accounts unfrozen: “Stop being a part of the blockade,” she said.

Public Safety Minister Marco Mendicino said allowing police to designate Ottawa’s downtown a no-go zone has been particularly effective. About 100 police checkpoints remain.

The trucker protests grew until it closed a handful of Canada-U.S. border posts and shut down key parts of the capital city for more than three weeks.
