Video: Massive trucker protest takes over Ottawa. Justin Trudeau reportedly moved to secret location ahead of 'Freedom Convoy' rally.

 Truckers and protesters showed up in huge numbers as the Freedom Convoy descended upon Ottawa, Ontario. Despite subzero windchill temperatures on Saturday, Canadians mounted a large protest against vaccine mandates. Massive crowds peacefully protested against government overreach near Parliament Hill.

Truckers were protesting an order that went into effect on Jan. 15, requiring unvaccinated Canadian truckers re-entering the country from the U.S. to get tested for COVID-19 and quarantine themselves. There was reportedly a convoy of up to 50,000 Canadian truck drivers who traveled to Canada's capital to protest the vaccine mandates.

The CBC reported that Trudeau left Rideau Cottage early Saturday for security reasons, and was transported to a secret location with his family.

Trudeau's press secretary Ann-Clara Vaillancourt responded, "The Prime Minister is continuing to isolate in the National Capital Region & work remotely. We’ve consulted Ottawa Public Health on appropriate protocols. As always, we do not comment on security matters."

Last week, Trudeau called the trucker convoy a "small fringe minority of people" who are "holding unacceptable views that they are expressing do not represent the views of Canadians who have been there for each other."

There were thousands of protesters, many waving Canadian flags and some were holding signs expressing contempt toward Trudeau.

There were reportedly volunteers handing out food and coffee to the protesters as well as people giving truckers gift cards.

Local authorities were forced to ask for backup from nearby communities as the crowds swelling in Ottawa. Gridlock from the rally caused Ottawa's downtown core to come to a complete standstill, and police said there was no more room for vehicles.

One trucker explained that it isn't about the vaccine, it's about "choice," "freedom," and "liberty."

"We are all together. We are all Canadians. We are all truckers," he said.

Rebel News founder Ezra Levant gave a speech at the Freedom Convoy rally.

The protest continued into the night with fireworks and a party-like atmosphere.

Some truckers said they plan on continuing their protest against the vaccine mandates, and will sleep in the cabs of their trucks.

In a letter to the truckers, Saskatchewan Premier Scott Moe pledged to end proof of vaccination policies in the province.

"My government supports your call to end the cross border ban on unvaccinated truckers," Moe said in the statement released on Saturday. "And it is why, in the not too-distant future, our government will be ending our proof of negative test/proof of vaccination policy in Saskatchewan."

Russell Brand, Don Cherry, Joe Rogan, Jordan Peterson, and Elon Musk have voiced their support of the "Freedom Convoy."

During a rally in Texas on Saturday night, former President Donald Trump delivered an endorsement of the Canadian truckers.

"We want those great Canadian truckers to know that we are with them all the way," Trump said. "They are doing more to defend American freedom than our leaders by far."
