TORONTO, Canada (AP) — In a scene at odds with Canadians’ reputation for niceness and rule-following, thousands of protesters railing against vaccine mandates and other COVID-19 restrictions descended on the capital over the weekend, deliberately blocking traffic around Parliament Hill.

Some urinated and parked on the National War Memorial. One danced on the Tomb of the Unknown Soldier. A number carried signs and flags with swastikas.

In the aftermath of Canada’s biggest pandemic protest to date, the demonstrators have found little sympathy in a country where more than 80 per cent are vaccinated. Many people were outraged by some of the crude behavior.

Prime Minister Justin Trudeau called the Ottawa protesters a “fringe minority” and said they reflected the proliferation of “disinformation and misinformation online, conspiracy theorists about microchips [and] about God knows what else that go with the tinfoil hats”.

Organisers, including one who has espoused white supremacist views, had raised millions for the cross-country “freedom truck convoy” against vaccine mandates. It attracted support from former US President Donald Trump and Tesla billionaire Elon Musk.

Trudeau and his family were moved to an undisclosed location during the protest. (Two of his children tested positive for COVID-19, and a test Monday revealed he, too, was infected. He said he is fine and working remotely. )

A smaller but still significant number of protesters remained on the streets on Tuesday.

“You had your 15 minutes. Time to move on and give back our city to our residents,” Ottawa Mayor Jim Watson said.

Those who stayed said they won’t leave until all vaccine mandates and other restrictions are gone. They are calling for the removal of Trudeau’s Government, though it is responsible for few of the measures, most of which were put in place by provincial governments.

Protester Michelle Kloet, 47, of Canmore, Alberta, tried to clean up some of the mess left behind, picking up empty liquor bottles and beer cans. She said she was there because “it’s time for Canada and the rest of the world to find other ways to deal with this virus”.

During the demonstration the statue of Terry Fox, a national hero who lost a leg to bone cancer as a youngster and set off in 1980 on a fund-raising trek across Canada, was draped with an upside-down Canadian flag and a sign that read “Mandate freedom”.

“My kids were shocked. Like all Canadian young people, they have grown up with Terry Fox as a hero,” Deputy Prime Minister Chrystia Freeland said. “This is not the Canada who we want to be. And I really 2proudly believe, and I know, this is not what Canada is.”

Conservative Ontario Premier Doug Ford said he was “extremely disturbed” to see people “desecrate our most sacred monuments and wave swastikas and other symbols of hate and intolerance”.

The outburst was seen as so out of character for Canada that one US scientist felt compelled to apologise for what he portrayed as America’s influence.

“Canada gave us kindness, tolerance, poutine and hockey, and in turn we exported this awful fake health freedom movement linked to far right extremism that caused so much senseless loss of life in America and now might do the same there,” tweeted Dr Peter Hotez, an infectious disease specialist at Baylor College of Medicine in Texas. “Our apologies.”

Many of the demonstrators refused to wear masks in hotels, malls and grocery stores. One homeless shelter reported protesters had demanded it feed them.

Ottawa Police Chief Peter Sloly said several investigations are underway and a tip line for hate crimes, threats and assaults related to the demonstration has been set up. Sloly said one person had been arrested in connection with the protest.

Tim Abray, a PhD candidate, said he was assaulted by “so-called freedom fighters” while taking pictures of the protest in his neighbourhood.

The most visible contingent of protesters were truckers who parked their big rigs on Parliament Hill, though they were in the minority of the thousands who turned out.

Some of the truckers were protesting a rule that took effect January 15 requiring those entering Canada to be fully immunised against the novel coronavirus. The US has imposed the same requirement on incoming truck drivers, so it would make little difference if Canada lifted its rule.

Some Opposition Conservative lawmakers attended the protest, and Conservative Party leader Erin O’Toole, who is facing a revolt among his lawmakers, met with some of the truckers.

Phil Haggart, a counter-protester, said he was there to show that there are voices in favour of public health measures.

“Masks are important, vaccines are important, and mandates are important only because we need them to stay alive and not fill our hospitals up,” he said.

A surge of the highly contagious Omicron variant has led to record cases and lockdowns in Ontario and Quebec, Canada’s most populous provinces. But restaurants reopened Monday with 50 per cent capacity, and vaccine mandates imposed by the provincial governments remain in place.

Nelson Wiseman, a political science professor at the University of Toronto, said the misinformation rabbit hole in Canada is not as deep as it is in the US for many reasons, including less political polarisation north of the border.

“This leads to much less sympathy for or tolerance of the unvaccinated among Canadians. Florida Governor Ron DeSantis could not get very far in Canada. A Donald Trump would be shunned, even in Conservative Party circles,” Wiseman said.

He added: “The protesters in Ottawa have not aided their cause as the demonstration drags on.”
