The international border crossing has been blocked since Monday. Early Friday, protesters agreed to allow one lane of traffic to open, allowing traffic to enter Canada from the bridge.

The Automotive Parts Manufacturers' Associationand Canadian Vehicle Manufacturers' Association are the main applicants on the injunction, due to the industry's reliance on the bridge for the exchange of vehicles and parts.

Automakershave beenscaling back production on both sides of the border this weekdue to the protests.

Ford declared the state of emergency as similar protests continue in Ottawa and along Highway 402, heading to the Blue Water Bridge international crossing in Sarnia, Ont.

The premier saidhe will convene cabinet and "urgentlyenact orders that will make crystal clear it is illegal and punishable to block and impede the movement of goods, people and services along critical infrastructure."

"This will include protecting international border crossings, 400-series highways, airports, ports, bridges and railways. It will also include protecting the safe and essential movement of ambulatory and medical services, public transit, municipal and provincial roadways, as well as pedestrian walkways," Ford said.

"Fines for non-compliance will be severe, with a maximum penalty of $100,000 and up to a year imprisonment. We will also provide additional authority to consider taking away the personal and commercial licenses of anyone who doesn't comply with these orders."

The White House saidU.S. officials had multiple conversations on Thursday with their Canadian counterparts,offering to help the Trudeau government bring an end to the blockade.

"[They] have been engaged around the clock to bring this to a swift end," the White House said in response to questions from CBC News.

Protest a 'national crisis,'says mayor

Windsor Mayor Drew Dilkens is calling the protest an "national crisis" due to the economic impact onboth Canada and the U.S.

Speaking with CBC News on Friday, the mayor said more police and RCMP are expected to arrive inWindsor.

"The goal is the preservation of life, I don't want anyone to die over this at the end of the day we need to find a way to move them peacefully," Dilkens said.

"So there's lots of resources coming, and the goal and objective here is to have theirprotesters leave voluntarily we do not want anyone to get hurt.... But if they refuse to leave, steps will have to be taken to remove them."

The mayor said that if an injunction is granted and police move in, there may be "prospect for arrest."

Dilkenssaid he worried about tensions risingfurther, citing an altercation that took place between protesters andpolice trying to move a car blockingAssumption College Catholic High School a school in the heart of the protest area. He said a "group with tire irons swarmed the police," who were ultimately able to de-escalate that situation.

"People on the ground here are speaking to media, saying they're willing to fight to the death for the reasons why they're here. And the irony is they're a leaderless group," said Dilkens.

Schools go online over protest concerns

Three Windsor schools movedto online learning onFriday over concerns that the protest may disrupt traffic.

The change comes after consultation with the Windsor Police Service, which said protesters may be "increasing their presence" around the schools, the local English Catholicboard said in a letter to the school communities.

The head of the Windsor-EssexChildren's Aid Society took to Twitter Thursday, asking protesters to leave children out of the demonstration.

"Respectfully, please leave your children at home should you choose to participate in the protest at the border. As tensions mount, the threat of disorder is increasing. You do not want your children exposed to this, or to risk their safety," wroteDerrick Drouillard.

Referring to a photo circulatingon social media Thursday, Windsor's mayor also showed concern about the potential of children being brought to the protest.

"The fact that I see a picture yesterday where [protesters]brought what looks like a bus of kids to hold hands across HuronChurch Road even thoughit was blocked holy moly, I question the sanity in a decision like that," he said.

Dilkens said that he hopes not to have ascene similar to what's been happening in Ottawa, where large numbers of children at tense protests are making it difficult for police to navigate the situation.

"Police are smart.Police are doing all they can. They have lots of intelligence, lots of resources."
