Massive demonstrations where the protestors are demanding an end to Canadian COVID-19 vaccine mandates have caused gridlock in the capital Ottawa since late January. The protests by truckers and others are now spilling to key Canada-United States border crossings and disrupting trade.

Reuters reported that the mayor of Windsor, Ontario, where protesters have closed the Ambassador Bridge border crossing to the United States, choking trade, said police were preparing to physically remove protesters if necessary.

How did the protests breakout?

In late January, the “Freedom Convoy” driving across Canada toward Ottawa ostensibly opposed vaccinate-or-quarantine mandates for cross-border truckers. But most truckers do not support the convoy.

Copycat protests have also sprung up in Australia, New Zealand and France, while truckers in the United States have said they are planning similar demonstrations. Organisers online have said a demonstration planned for Monday in Belgium’s capital, Brussels, will see convoys merge from countries across Europe.

Reuters reported that the protests may have contributed to the opposition Conservative Party’s ousting of leader Erin O’Toole, who angered some Conservative legislators for initially distancing himself from the protests.
