INTERNATIONAL: After nearly a week of being under blockade commercial and personal traffic is now flowing freely between Canada and Detroit Monday morning , February 14.

North America's busiest trade link reopened for traffic late Sunday evening, ending a six-day blockade, Canada Border Services Agency has announced, after Canadian police have cleared the protesters fighting to end Covid-19 restrictions.

Police barricades closely guard the entrance to the bridge access roads, watching for for anyone who may try to stop traffic again.

Canadian police have made several arrests on Sunday and cleared protesters and vehicles that occupied the Ambassador Bridge in Windsor, Ontario, after a court order on Friday.

The blockade had choked the supply chain for Detroit's carmakers, forcing Ford Motor Company, the second-largest U.S. automaker, General Motors Companhy and Toyota Motor Corporation to cut production.

The bridge carries about $360 million a day in two-way cargoes – 25 percent of the value of all U.S.-Canada goods trade.

A Windsor Police official has told reporters that 20 to 30 arrests had been made.

Police have also seized vehicles within the demonstration area, according to an earlier statement.

Police have stepped up their presence on Sunday with more than 50 vehicles, including cruisers, buses and an armored car, as the number of protesters dropped to around 45 from roughly 100 on Saturday.

Windsor Police have added "there will be zero tolerance for illegal activity".
