Organizers of a demonstration protesting vaccine mandates outside Canada's Parliament have reportedly said they have enough money to keep trucks there for up to four years. Thousands of protesters converged on Parliament Hill in Ottawa over the weekend, joined by truckers who had traveled across Canada as part of a Freedom Convoy." Although initially organized to oppose vaccine mandates for truck drivers crossing the Canada-U.S. border, it has grown in recent days into a movement against COVID-19 restrictions in general, and Justin Trudeau's government. The demonstration in Ottawa on Saturday saw truckers block the streets around Canada's parliament building. It comes as a GoFundMe campaign called "Freedom Convoy 2022" surpassed more than $7.1 million ($9.1 million CAD) in donations. Ottawa Police said on Sunday that officers have been "actively and patiently managing a well-funded, major demonstration in the downtown core" and that there had been "multiple cases of disruptive, inappropriate and threatening behavior from demonstrators." Police "are aware that many demonstrators have announced their intention to stay in place," the statement added. "This will continue to cause major traffic, noise and safety issues in the downtown core. We urge all residents to avoid travel to the core." Trudeau and his family left their home in Ottawa over security concerns. The Canadian leader has called the protesters a "small fringe minority."
