TORONTO (AP) — Prime Minister Justin Trudeau said Monday emergency powers are still needed despite police ending border blockades and the occupation of the nation’s capital by truckers and others angry over Canada’s COVID-19 restrictions.

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

Lawmakers in Parliament will vote Monday night whether to allow police to continue to use emergency powers. Opposition New Democratic Party leader Jagmeet Singh said his party will support it, ensuring Trudeau should have enough votes.

Trudeau noted there are some truckers that are just outside Ottawa that may be planning further blockades and his public safety minister noted there was an effort to block a border crossing in British Columbia on 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 compels tow truck companies to tow away vehicles.

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 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.

“We saw calm, peace and quiet,” Mendicino said.

Singh, the opposition New Democratic leader, said they know there are protesters waiting in the surrounding areas of Ottawa and in the capital itself. “They need to be cleared out,” Singh said.

Singh 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,” Singh said. “The organizers clearly have a goal in mind to undermine democracy. That’s something we can’t allow to continue.”

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.

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. The relentless blare of truckers’ horns has gone silent. A large police presence remains in Ottawa and some areas are fenced off.

The protests, which were first aimed at a COVID-19 vaccine mandate for cross-border truckers but also encompassed fury over the range of COVID-19 restrictions and hatred of Trudeau, reflected the spread of disinformation in Canada and simmering populist and right-wing anger.

The self-styled Freedom Convoy shook Canada’s reputation for civility, inspired convoys in France, New Zealand and the Netherlands and interrupted trade, causing economic damage on both sides of the border. Hundreds of trucks eventually occupied the streets around Parliament, a display that was part protest and part carnival.

For almost a week the busiest U.S.-Canada border crossing, the Ambassador Bridge between Windsor, Ontario and Detroit, was blocked. The crossing sees more than 25% of the trade between the two countries.

Authorities moved to reopen the border posts, but police in Ottawa did little but issue warnings until Friday, even as hundreds and sometimes thousands of protesters clogged the streets of the city and besieged Parliament Hill.

On Friday, authorities launched the largest police operation in Canadian history, arresting a string of Ottawa protesters and increasing that pressure on Saturday until the streets in front of Parliament were clear. Eventually, police arrested at least 191 people and towed away 79 vehicles. Many protesters retreated as the pressure increased.

Trudeau said people in Ottawa were harassed for weeks and said billions of dollars in trade were stalled by the border blockades, putting people’s jobs at risk.

The protests have been cheered on in the U.S. by Fox News personalities and conservatives like former U.S. President Donald Trump. Millions of dollars in donations have flowed across the border to the protesters.

“A flood of misinformation and disinformation washed over Canada, including from foreign sources,” Trudeau said.

“After these illegal blockades and occupations received disturbing amounts of foreign funding to destabilize Canada’s democracy it became clear that local and provincial authorities needed more tools to restore order.”
