Toronto, the largest city in Canada, is moving into lockdown -- its highest alert, what it calls grey status -- as it tries to mitigate an increasing coronavirus emergency.

The Peel Region, just west of Toronto and including Mississauga, will also be placed in the grey status.

As part of the designation, public or social indoor gatherings are not allowed. Weddings, funerals or religious services may have up to 10 people indoors. All outdoor gatherings cannot include more than 10 people.

Also, restaurants and bars may have no indoor or outdoor service though takeout is permitted. Essential retail, like pharmacies and grocery stores, can open, but at 50% capacity. All other retail is closed except for curbside pickup.

Casinos, movie theaters and museums will all be closed. Media production facilities, including Toronto's thriving film industry, can only operate with proper social distancing on set.

Cases in Toronto have gradually increased since maintaining a seven-day average of under 100 per day through most of August. The city reported a one-day high of 1,581 cases on Nov. 14 and the seven-day average reported Friday was 1,373 per day.

States reported more than 1,800 deaths for the third day in a row on Friday, according to The COVID Tracking Project.

There were 1,862 deaths reported.

Daily COVID-19 tests, cases and current hospitalizations broke new records on Friday, the tracker said, surpassing all-time highs reached Thursday.

States reported over 1.9 million daily tests and 192,805 new cases, and 82,178 people are currently hospitalized with COVID-19, according to the tracker. 

Three states are reporting over 500 hospitalizations per million people: North Dakota, South Dakota and Nebraska.

Donald Trump. Jr. is the latest person connected to the White House to test positive for the coronavirus, a spokesman confirmed to ABC News.

“Don tested positive at the start of the week and has been quarantining out at his cabin since the result. He’s been completely asymptomatic so far and is following all medically recommended COVID-19 guidelines,” the spokesman said in a statement.

The president's eldest son is the second of his children to test positive for the virus, following Barron Trump's diagnosis last month.

The U.S. Food and Drug Administration announced Thursday that its vaccine advisory committee will meet Dec. 10 to discuss the request for emergency use authorization of Pfizer's COVID-19 vaccine candidate.

The public meeting will be a chance for both FDA career scientists and members of the independent advisory board to ask Pfizer questions about its product. 

After that, the board will make a recommendation, which the FDA will take into account when it decides whether to authorize the vaccine.

Officials said they cannot predict how long the FDA's review will take, but that it will be "as expeditiously as possible, while still doing so in a thorough and science-based manner."

Around 4,000 people in South Australia have been ordered to quarantine as the Australian state grapples with a fresh COVID-19 outbreak.

South Australia authorities announced five new locally-transmitted cases on Tuesday, at least four of which were officially linked to a medi-hotel in the Parafield suburb of Adelaide, where travelers arriving from abroad are required to quarantine for 14 days. Authorities said the fifth case is expected to be connected to the Parafield cluster soon, which would bring the total number to 21.

"All of these people have either no symptoms or they are very mildly symptomatic, and they have been picked up early in the course of the disease," South Australia’s chief health officer, Prof. Nicola Spurrier, said at a press conference Tuesday.

Those who have been advised to isolate are all close contacts of the cluster from the quarantine hotel and are being contacted daily by health authorities to check for symptoms. Meanwhile, at least five schools have been closed as contact tracers work to contain the outbreak, according to Spurrier.

"We've decided to take a very, very cautious approach," she told reporters, later adding that "this is a very, very worrying situation."

Thousands of people have been tested for COVID-19 in South Australia in recent days. Spurrier urged people to only get tested if they are symptomatic or if they have recently visited the areas of concern.

"We do need to prioritize our testing across South Australia," she said.

There are currently 34 active infections in the state, including imported cases. The latest cluster is the first instance of community transmission in South Australia since April.

"I need to reiterate to the people of South Australia that we are not out of the woods yet," the state's premier, Steven Marshall, said at Tuesday's press conference. "We are just at the beginning stages of dealing with this particular very nasty cluster in Parafield. We are going to get through this. But we’re going to get through it with the cooperation of every single South Australian citizen."
