It marked a rare public outing for the Canadian leader since the start of the COVID-19 pandemic, as protests spread outside the United States after police in Minnesota killed an unarmed black man.

“Far too many Canadians feel fear and anxiety at the sight of law enforcement officers,” Trudeau told his daily briefing earlier in the day.

“Over the past weeks, we’ve seen a large number of Canadians suddenly awaken to the fact that the discrimination that is a lived reality for far too many of our fellow citizens is something that needs to end” , AFP reported.

Trudeau, holding a “Black Lives Matter” T-shirt, chanted from behind a mask along with the crowd that extended several blocks to the US embassy, and later stood in silence for eight minutes and 46 seconds.

This was the length of time that a white police officer in Minneapolis knelt on the neck of George Floyd, an unarmed African-American, who died after pleading “I can’t breathe.”

Video of Floyd’s May 25 death has gone viral and sparked sometimes violent protests across the United States and mass demonstrations in European capitals and elsewhere.

“Look at the diversity of this crowd,” said Families Minister Ahmed Hussen, who joined Trudeau at the Ottawa protest. “These are not just black Canadians. It’s everyone who’s saying black lives matter.”

Similar protests took place in cities across Canada.

In Toronto, Police Chief Mark Saunders and several uniformed officers met protestors marching through downtown, and also took a knee.

“We see you and we are listening,” he tweeted. “We have to all stay in this together to make a change.”

Saunders’ actions drew praise from Ontario Premier Doug Ford, who called images of the city’s first black police chief joining protestors “impactful.”

“That’s what you call true leadership,” he said.

Ottawa protestor Stephane Kribodo said there was too much racism — “in the world, in France, in the United States, in Canada.”

“It’s important to stand up against it if we want to change,” he said.

Another protestor, Sophie Scott, echoed this view, noting several recent cases of alleged police misconduct in Canada.

Two women with mental health problems, in Toronto and the town of Edmundston, New Brunswick, died after calling the police for help. An Inuit man in the far north was struck by a police cruiser.

“We want a just (pandemic) recovery for all and that requires taking action against racism,” Scott said.

On Tuesday, Trudeau appeared at a loss for words, pausing for 20 seconds when pressed for his thoughts on US President Donald Trump’s threat of military mobilization against violent protests.

“We all watch in horror and consternation what’s going on in the United States,” he said finally.

Now “is a time to listen, it is a time to pull people together and a time to learn what injustices continue despite progress over years and decades,” he added.

Meng Wanzhou, Huawei’s global chief financial officer, was arrested in Canada on Dec. 1 and faces extradition to the United States, which alleges that she covered up her company’s links to a firm that tried to sell equipment to Iran despite sanctions.

The executive is the daughter of the founder of Huawei.

If extradited to the United States, Meng would face charges of conspiracy to defraud multiple financial institutions, a Canadian court heard on Friday, with a maximum sentence of 30 years for each charge.

No decision was reached at the extradition hearing after nearly six hours of arguments and counter-arguments, and the hearing was adjourned until Monday.

In a short statement, China’s Foreign Ministry said that Vice Foreign Minister Le Yucheng had issued the warning to release Meng to Canada’s ambassador in Beijing, summoning him to lodge a “strong protest”, Reuters reported.

There was no immediate reaction from the office of Canadian Foreign Minister Chrystia Freeland on Saturday. When asked about the possible Chinese backlash after the arrest of Huawei’s CFO, Prime Minister Justin Trudeau told reporters on Friday that Canada has a very good relationship with Beijing.

Canada’s arrest of Meng at the request of the United States, while she was changing plane in Vancouver, was a serious breach of her lawful rights, Le said.

The move “ignored the law, was unreasonable” and was in its very nature “extremely nasty,” he added.

“China strongly urges the Canadian side to immediately release the detained person, and earnestly protect their lawful, legitimate rights, otherwise Canada must accept full responsibility for the serious consequences caused.”

The statement did not elaborate.

“There will probably be a deep freeze with the Chinese in high-level visits and exchanges,” David Mulroney, former Canadian ambassador to China, said on Friday.

Meng’s arrest was on the same day that US President Donald Trump met in Argentina with China’s Xi Jinping to look for ways to resolve an escalating trade war between the world’s two largest economies.
