Prime Minister Justin Trudeau on Monday invoked the national Emergencies Act to bring to an end the antigovernment blockades he described as illegal and not about peaceful protest.

The government will use the act to force towing companies to remove big rigs and other vehicles that are blocking highways and other critical infrastructure, establish zones where public assembly is not allowed, and require banks to suspend or freeze accounts suspected of supporting the blockades, including those belonging to companies whose trucks are part of the convoy.

Deputy Prime Minister Chrystia Freeland said the government is “serving notice” to trucking companies with vehicles involved in any of the blockades that they will have their corporate accounts frozen and lose their insurance.

“Consider yourselves warned,” she said. “Send your semi-trailers home. The Canadian economy needs them to be doing legitimate work, not to be illegally making us all poorer.”

Freeland said every day the Ambassador Bridge was closed $390 million worth of trade was halted. Every day the border remains closed in Coutts, Alta., she said it affects $48 million of trade, and in Emerson, Man., $73 million a day.

The government is invoking the act under the public order section, meaning they believe the blockades are a threat to national security. As such the act will apply across the country, including in provinces where premiers said Monday they did not think it was needed.

Trudeau however said the orders would only target specific places that are being blockaded. He spoke to premiers by phone Monday morning, following an urgent cabinet meeting Sunday night. He also briefed the Liberal caucus first thing Monday.

“I want to be very clear: the scope of these measures will be time-limited, geographically targeted, as well as reasonable and proportionate to the threats they are meant to address,” Trudeau said at a news conference late in the afternoon.

He said it does not involve bringing in the military, or suspending fundamental rights under the Charter of Rights and Freedoms.

The premiers in Quebec, Alberta, Saskatchewan and Manitoba all said they didn’t want the act used in their provinces, but didn’t oppose it being used elsewhere, particularly Ontario.

“In my view, the sweeping effects and signals associated with the never-before-used Emergencies Act are not constructive here in Manitoba, where caution must be taken against overreach and unintended negative consequences,” Manitoba Premier Heather Stefanson said.

British Columbia’s solicitor general, Mike Farnworth, said his province supports Trudeau’s use of the act “to deal with this situation back east.” A blockade has also limited or closed access to the US border crossing at Surrey, B.C., for several days now.

Alberta Premier Jason Kenney said invoking it for his province could actually inflame tensions. He called on Trudeau instead to work with US President Joe Biden to lift vaccine mandates at the border.

Federal Conservative Leader Candice Bergen said Monday the party still had to study the orders the Liberals are making but she said she had some serious concerns.

Earlier Monday, the Liberals and New Democrats joined to defeat a Conservative motion, supported by the Bloc Quebecois, asking the federal government for a plan to lift remaining COVID-19 restrictions.

Police in Windsor, Ont., managed to clear a weeklong blockade at the Ambassador Bridge Sunday, resulting in 25 to 30 arrests and the seizing of many vehicles. In Coutts, Alta., a blockade that began Jan. 29 continues but RCMP Monday arrested 11 people at the site and seized 13 long guns, handguns, body armour, a machete, a large quantity of ammunition and high-capacity magazines.

Trudeau said police have been doing what they can but there are serious challenges that require the use of the Emergencies Act. It comes after multiple court injunctions against noise and blockades in Ottawa and Windsor, including a new one Monday from an Ontario judge to enforce Ottawa bylaws against noise, idling, open fires and setting off fireworks.

Still the blockade in Ottawa, which is now well into its third week, continued unabated Monday and many trucks returned to blasting their horns, a week after a provincial judge issued an injunction against the noise that seemed to temporarily quiet them.

Protesters were dancing, eating and even lifting weights at an outdoor gym set up using red plastic jerry cans to hold the weight bar, beside a sign designating the space “Muscle Beach.”

Banners waving on ropes tied to the gates around Parliament Hill claimed Ottawa residents needed to remember this is “also our home” and welcomed people to the “segregated citizens zone” of the “Freedom Convoy Communauty” (sic).

Many were not moved at all by the Emergencies Act invocation.

Some trucks moved from residential side streets to Wellington Street right in front of Parliament Monday, with a police escort. But Peter Unger, on his 17th day demonstrating in Ottawa, said he hadn’t been told to move from his spot several blocks from Parliament Hill and had no plans to.

“There is no emergency here. All (Trudeau) needs is to come out and talk to us. We’re willing to listen,” Unger said.

Justice Minister David Lametti said invoking the Emergencies Act will allow cabinet to regulate and prohibit public gatherings in specific places, such as at borders, on roads leading to and from those borders or to other critical infrastructure such as airports, and in Ottawa.

It will also allow cabinet to designate towing companies as essential services to compel them to remove big rigs and other vehicles from the blockades. That is something many companies have refused to do for fear of reprisal from the truckers and others involved in the convoys. Trudeau said clearing trucks at the Ambassador Bridge in Windsor, Ont., on the weekend happened only because of the co-operation of American towing companies.

The city of Ottawa said Monday it would deploy some of the big towing rigs used by the city’s public transit system.

The orders will heavily target the financing for the convoy, which has in large part come from foreign sources using crowdfunding platforms and cryptocurrencies. One of the temporary measures includes adding those entities to Canada’s anti-money laundering and terrorist financing laws, but Freeland said legislation to make that change permanent will eventually be introduced.

It means platforms like GoFundMe will need to register with Canada’s finance intelligence service known as Fintrac and report all large or suspicious transactions.

“It’s all about following the money,” Freeland said. “It’s about putting an end to the funding of these illegal blockades.”

GoFundMe cancelled a convoy fundraiser that had raised about $10 million, saying it violated its terms of service and is refunding the money. The convoy leaders then turned to US Christian funding platform GiveSendGo, which collected about $9 million. That platform was down on Monday after it was apparently hacked and donor info was leaked.

Some convoy operators were also discussing raising money using cryptocurrencies such as Bitcoin.

Trudeau and Freeland made clear that they believe the protests threaten Canada’s economic security and its reputation internationally.

“International confidence towards Canada as a good place to invest and do business has been shaken,” Freeland said.

Biden said last week he expected Canada to solve the crisis that was affecting trade at the border.

The act can only be invoked for 30 days but Lametti said he’s hoping it won’t take that long to bring things under control.

This is the first time the Emergencies Act has been invoked since it came into force in 1988.
